UNITED STATES OF AMERICA, 

 Plaintiff - Appellant

v.

RENIERI JOEL ROSALES-GIRON, 

 Defendant - Appellee

Appeal from the United States District Court

for the Southern District of Mississippi

USDC No. 3:13-CR-96-1

Before SMITH, BARKSDALE, and HAYNES, Circuit Judges.

PER CURIAM:*

This interlocutory appeal concerns the district court’s granting Renieri 

Rosales-Giron’s motion to suppress, regarding a Mississippi Highway Patrolman’s 

conducting a traffic stop of Rosales’ vehicle. Primarily at issue is whether the 

Trooper had probable cause to believe Rosales committed a traffic violation 

(careless driving), justifying the stop. REVERSED and REMANDED. 

* Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not 

be published and is not precedent except under the limited circumstances set forth in 5th Cir. 

R. 47.5.4.

No. 14-60149

I.

The following factual recitation is based on evidence presented by the 

Government (testimony by the Trooper and his video recording of Rosales’ vehicle) 

at the hearing on the suppression motion. Rosales did not present evidence.

The Trooper was assigned to the Highway Patrol’s Traveling Criminal 

Apprehension Program, which focuses on interstate criminal activity. On 23 

October 2013, he was in the median of Interstate 20 at mile-marker 61 in Rankin 

County, Mississippi. In the median, his vehicle was surrounded by an open area 

with an unobstructed view of oncoming and passing traffic. While observing 

eastbound traffic, the Trooper heard the sound of an eastbound vehicle driving on 

the rumble strips (the indentations on the side of the road that alert drivers to 

alter their trajectory), outside (to the right of) the fog line (a white line on the right 

side of the right lane on a highway). Because this rumbling “caught [his] eye”, the 

Trooper concluded the vehicle had run off the road. 

Based on his training, the Trooper was suspicious of the vehicle, a van. He 

knew perpetrators of crimes involving highway transportation of illegal drugs and 

aliens often operate with two vehicles: the first serves as a decoy to attract the 

attention of law-enforcement officers, while the second perpetrates the principal 

offense, such as transporting drugs or aliens. Consequently, the Trooper waited 

about one minute to pursue the van, after concluding another vehicle was not 

following it. 

After reaching the van in approximately one minute, the Trooper drove 

side-by-side with it and observed it move over onto the fog line. (The Trooper was 

unable to see into the van because its windows were tinted black.) He then 

changed lanes, drove behind the van, and activated his vehicle’s bar light (blue). 

A video camera displaying a Trooper’s view from the front of his vehicle activates

automatically when the vehicle’s bar light is activated. (The Trooper could not 

recall whether he manually initiated the recording or whether it commenced 

2

 Case: 14-60149 Document: 00512837615 Page: 2 Date Filed: 11/14/2014
No. 14-60149

because he activated the bar light.) Subsequently, the Trooper observed the van

drive on (“hit” or “bump”) the fog line (depicted in the video recording), which 

prompted him to conduct the stop. 

The Trooper stopped the van for careless driving, a violation of Mississippi 

law. Miss. Code Ann. § 63-3-1213 (“Any person who drives any vehicle in a careless 

or imprudent manner, without due regard for the width, grade, curves, corner, 

traffic and use of the streets and highways and all other attendant circumstances 

is guilty of careless driving.”). Rosales was the driver of the van. The Trooper 

issued him a warning citation for, inter alia, careless driving. During the stop, 

the Trooper discovered numerous individuals in Rosales’ vehicle, later claimed to 

be illegal aliens. 

On 23 November 2013, Rosales was charged in a single-count indictment 

with transporting aliens for the purpose of commercial advantage or private gain,

in violation of 8 U.S.C. § 1324(a)(1)(A)(ii). He moved to suppress the evidence 

discovered during the stop. In that regard, as expressed during the suppression 

hearing, Rosales challenged only whether the initial stop was lawful, not any of 

the conduct following the stop. 

In his suppression-hearing testimony, the Trooper explained why he 

stopped Rosales. The Trooper justified the stop based only on violations of 

Mississippi’s careless-driving statute, which he explained occurred three times: 

Rosales drove on the rumble strips, outside of the fog line, when he passed the 

Trooper at mile-marker 61; and Rosales hit or bumped the fog line twice after the 

Trooper began following him–while the Trooper and Rosales were side-by-side and 

later, when the Trooper was behind Rosales while the video camera was recording. 

Concerning the Trooper’s observing Rosales’ hitting the fog line, the Government 

asked the Trooper: “So did he run off the side of road more than once before you 

stopped him?” He replied: “Yes. He was weaving once I pulled out on him as well. 

He hit [the fog line] a couple of times.” 

3

No. 14-60149

The video recording made by the Trooper was shown during the hearing, 

with his being questioned about it while it was being shown. As noted, Rosales 

did not present evidence. 

In ruling from the bench, the district court stated: “I would have a hard 

time sustaining the ticket for careless driving when the driver didn’t run off the 

road” and “ran over the fog line because the Trooper was riding along – beside 

him. That would make me nervous to have . . . a trooper riding beside me for an 

extended period of time”. Regarding the vehicles being side-by-side, the court 

found, inter alia, that Rosales “simply moved over and happened to run onto the 

fog line”. The court stated to the Government: “You’d be raising Cain with the 

judge if you got a ticket for deviating six inches . . . onto the white [fog] line . . . , 

wouldn’t you?” In granting the motion, the court ruled: “There just simply was 

not enough carelessness in this to be a danger to anybody”. 

The Government’s motion for reconsideration was denied. United States v. 

Rosales, No. 13-CR-96 (WHB-FKB), slip op. at 1-4 (S.D. Miss. 26 Feb. 2014) 

(unpublished). In doing so, the court elaborated on its rationale for suppressing 

the evidence: the Trooper lacked credibility because, first, he could not have heard

Rosales’ vehicle driving on the rumble strips when it passed him at mile-marker 

61; second, Rosales’ driving on the fog line once without other evidence of unsafe 

or impaired driving was insufficient to justify a stop (was not careless driving); 

and third, the Trooper’s actions in following the van did not support the reason 

provided for the stop by the Trooper – the court stated that, instead of stopping 

the van promptly, the Trooper stopped the van because of the Trooper’s extensive 

experience and only after he followed Rosales for a considerable distance, noted 

the van’s out-of-state license plate, and observed Rosales’ ethnicity. (But 

regarding ethnicity, and as noted, the Trooper was unable to see into the van 

because its windows were tinted black.)

II.

Pursuant to 18 U.S.C. § 3731 (“An appeal by the United States shall lie to 

a court of appeals from a decision . . . of a district court suppressing or excluding 

evidence . . . in a criminal proceeding . . . .”), we have jurisdiction for this 

interlocutory appeal. It goes without saying that, generally, “[t]he government 

may not use evidence obtained in violation of the Fourth Amendment’s prohibition 

against unreasonable searches and seizures to prove a defendant’s guilt at trial”. 

United States v. Breeland, 53 F.3d 100, 102 (5th Cir. 1995). 

In appeals concerning suppression of evidence, the district court’s legal 

conclusions are reviewed de novo; its findings of fact, for clear error. E.g., United 

States v. Jenson, 462 F.3d 399, 403 (5th Cir. 2006) (citation omitted). “A finding 

of fact is clearly erroneous when[,] although there is evidence to support it, the 

reviewing court on the entire evidence is left with a firm and definite conviction 

that a mistake has been committed.” United States v. Gomez-Moreno, 479 F.3d 

350, 354 (5th Cir. 2007) (citation and quotation marks omitted). 

As reflected in the clear-error standard, district courts are afforded 

substantial deference in their factual determinations, especially when, as here,

they involve credibility assessments derived from live testimony. E.g., United 

States v. Robinson, 741 F.3d 588, 594 (5th Cir. 2014) (citation omitted). The court 

not only observed, but questioned, the Trooper during the hearing and, as stated 

in the denial of the Government’s motion to reconsider, was “not convinced that 

the testimony of the [T]rooper was credible”, referencing: the first claimed offense,

when Rosales drove by the Trooper at mile-marker 61 (the court “doubt[ed]” the 

Trooper could hear the van driving on the rumble strips); the Trooper’s making 

the stop based on careless driving; and the stop, in the court’s view, being based, 

instead, on other factors, such as the van’s out-of-state tag.

For the first time on appeal, Rosales asserts the rumble strips were inside 

the fog line; therefore, according to Rosales, the Trooper’s testimony that he heard 

5

 Case: 14-60149 Document: 00512837615 Page: 5 Date Filed: 11/14/2014
No. 14-60149

Rosales drive on the strips does not mean Rosales necessarily crossed the fog line. 

We will not consider this fact-based issue, which was not raised in district court 

in support of Rosales’ motion to suppress. E.g., United States v. Pope, 467 F.3d 

912, 918-19 & n.20 (5th Cir. 2006). (Even if we were to review the issue instead 

for plain error, it would fail because, for such questions of fact, they cannot provide 

a basis for plain (clear or obvious) error. E.g., United States v. McCaskey, 9 F.3d 

368, 376 (5th Cir. 1993) (resolution of a factual issue not presented to the district 

court cannot be plainly erroneous in sentencing context).) 

For resolving this appeal, we need consider only the third claimed offense, 

which was recorded in, and verified by, the video while the Trooper was following 

the van, subsequent to having been beside it: the Trooper testified the van hit, or 

bumped, the fog line. In short, was this sufficient to justify the traffic stop? If it 

was, it is not necessary, as explained infra, to engage in a balancing analysis to 

determine whether the stop was otherwise justifiable based on reasonable 

suspicion. Accordingly, it would not be necessary to decide whether the district 

court clearly erred in finding, inter alia: the Trooper did not hear the van drive 

on the rumble strips at mile-marker 61; and, during the side-by-side instance, it 

was reasonable for the van to “[run] over on the fog line because the [T]rooper 

was riding . . . beside [it] . . . . for an extended period of time”. (Accordingly, 

contrary to the position taken by the dissent at 2, we do not “reverse the district 

court based upon testimony of the [T]rooper as the district court is entitled to 

make the credibility determinations based upon its live assessment of the 

witness”. As stated, regarding the third violation provided by the Trooper, the 

video shows the fog line was hit. United States v. White, 401 U.S. 745, 753 (1971) 

(“An electronic recording will many times produce a more reliable rendition . . . 

than will the unaided memory of a police agent.”); see also United States v. Vickers, 

442 F. App’x 79, 86, 87 & n.7 (5th Cir. 2011) (no error in disregarding witness’ 

testimony when testimony conflicted with video evidence). Likewise, despite the 

6

 Case: 14-60149 Document: 00512837615 Page: 6 Date Filed: 11/14/2014
No. 14-60149

dissent’s concerns at 6, remand is not required for the district court to clarify its 

findings of fact and conclusions of law.) 

“The reasonableness of traffic stops and investigative detentions of 

motorists who are suspected of criminal activity is analyzed under the framework 

established in Terry v. Ohio, 392 U.S. 1 (1968).” United States v. Stevens, 487 F.3d 

232, 244 (5th Cir. 2007) (citing cases). “Under Terry, we determine the 

reasonableness of an investigative stop by examining: (1) whether the officer’s 

action of stopping the vehicle was justified at its inception, and (2) whether the 

officer’s actions were reasonably related in scope to the circumstances that 

justified the stop.” Id. (citing Terry, 392 U.S. at 19-20). As noted, during the 

suppression hearing, Rosales expressly declined to contest the second prong of 

Terry, contesting only whether the stop was justified at its inception. Accordingly, 

we consider only the first prong of Terry. 

For a traffic stop to be justified at its inception, an officer need only have 

reasonable suspicion that “some sort of illegal activity, such as a traffic violation, 

occurred, or is about to occur, before stopping the vehicle”. United States v. LopezMoreno, 420 F.3d 420, 430 (5th Cir. 2005) (citing Breeland, 53 F.3d at 102). 

“Reasonable suspicion” analysis requires assessing the totality of the 

circumstances to ascertain the reasonableness of the suspicion. United States v. 

Powell, 732 F.3d 361, 369 (5th Cir. 2013) (citation omitted). This is consistent 

with the “touchstone of Fourth Amendment analysis [being] reasonableness”, 

which “requires a balancing of the public interest with an individual’s right to be 

free from arbitrary intrusions by law enforcement”. United States v. Brigham, 

382 F.3d 500, 507 (5th Cir. 2004) (en banc) (citations omitted). 

In that regard, the Supreme Court held unanimously in Whren v. United 

States, 517 U.S. 806 (1996): “As a general matter, the decision to stop an 

automobile is reasonable where the police have probable cause to believe that a 

traffic violation has occurred.” Id. at 810. “Probable cause exists when the totality 

7

 Case: 14-60149 Document: 00512837615 Page: 7 Date Filed: 11/14/2014
No. 14-60149

of facts and circumstances within a police officer’s knowledge at the moment of 

arrest are sufficient for a reasonable person to conclude that the suspect had 

committed, or was in the process of committing, an offense.” United States v. 

Zavala, 541 F.3d 562, 575 (5th Cir. 2008) (quoting United States v. Castro, 166 

F.3d 728, 733 (5th Cir. 1999) (en banc)). Therefore, probable cause to make a 

traffic stop exists, inter alia, when a defendant commits a traffic violation and a 

law-enforcement officer observes the violation. E.g., United States v. 

Khanalizadeh, 493 F.3d 479, 482 (5th Cir. 2007). “Where probable cause has 

existed, the only cases in which we have found it necessary actually to perform 

the ‘balancing’ analysis involved searches or seizures conducted in an 

extraordinary manner, unusually harmful to an individual’s privacy or even 

physical interests . . . .” Whren, 517 U.S. at 818. An “extraordinary-manner” 

exception is neither asserted, nor applicable, in this instance. 

As is well known, “[t]he rule established by the Supreme Court in Whren

allows officers to justify a stop by the occurrence of a traffic violation even though 

this is not the real reason for the stop”, United States v. Cole, 444 F.3d 688, 689 

(5th Cir. 2006); but, on the other hand, the legal justification for the traffic stop 

must be “objectively grounded”, id. (citation omitted). As noted, the district court 

concluded, inter alia, that the third claimed careless-driving offense, documented 

in the video recording, when Rosales hit the fog line, did not justify the stop. 

The Mississippi Court of Appeals, however, has found probable cause for a 

careless-driving violation based on hitting, or bumping, the fog line. In 2004, it 

ruled a court must reasonably interpret a wide range of factors when determining 

carelessness under the careless-driving statute. Henderson v. State, 878 So. 2d 

246, 247 (Miss. Ct. App. 2004). Subsequently, the court held an officer’s stating a

driver bumped the fog line was sufficient to constitute probable cause to stop the 

driver for careless driving. Dominick v. State, 108 So. 3d 452, 455-56 (Miss. Ct. 

App. 2012) (probable cause existed where an officer testified the defendant’s car 

8

 Case: 14-60149 Document: 00512837615 Page: 8 Date Filed: 11/14/2014
No. 14-60149

bumped the fog line prior to changing lanes and a review of videotape evidence 

did not contradict the officer’s testimony); Martin v. State, 43 So. 3d 533, 535 

(Miss. Ct. App. 2010) (“[T]he circuit court judge stated that[,] by his 

understanding of the rules of the road, hitting the fog line while driving clearly 

constituted probable cause for an officer to perform a traffic stop”, and “the circuit 

court did not err in finding that probable cause existed for the traffic stop”.). 

The underlying facts of these cases include additional incidences of 

carelessness, such as swerving or quickly driving back-and-forth, but they do not 

distinguish the importance of each violation in finding probable cause. See, e.g., 

Martin, 43 So. 3d at 535. Mississippi’s careless-driving statute is broadly worded 

to encompass drivers who fail to exercise “due regard for the width . . . of the 

streets and highways”, the offense for which the Trooper stopped Rosales. Miss. 

Code Ann. § 63-3-1213. We conclude from this broad language and the cited cases 

that a traffic stop for careless driving is justified in Mississippi when a lawenforcement officer observes an automobile hit the fog line. (The dissent fails to 

cite a Mississippi decision that holds a stop for careless driving is unjustified when 

a driver hits the fog line only once. Contrary to the dissent’s statement at 3, note 

2, our noting this failure is not a “suggestion that [the dissent] need[s] the support

of a Mississippi case [with that] holding”; on the other hand, the dissent’s failure 

to do so adds weight to our holding that there was probable cause for the stop in 

this instance after the van hit the fog line only once.) But, even if more is required

(as the dissent urges at 3-6), such additional factors exist preceding the third 

claimed offense, such as the van’s weaving when the Trooper pulled out from the 

median, and the van’s later hitting the fog line when the Trooper’s vehicle was 

beside the van. (For that side-by-side instance, although the court ruled it was 

reasonable for the van to do so in those circumstances, it nevertheless found the 

van ran on the fog line. Regarding a driver’s reaction in the presence of a lawenforcement vehicle, the dissent at 5–6, and note 5 at 6, fails to cite United States 

9

 Case: 14-60149 Document: 00512837615 Page: 9 Date Filed: 11/14/2014
No. 14-60149

v. Escalante, 239 F.3d 678, 681 (5th Cir. 2001). There, it was claimed the Deputy 

caused defendant to weave. But, in addition to stating defendant’s “arguments 

ha[d] persuasive force”, our court “recognize[d]” the Deputy had an equally valid 

position: a driver would not swerve even if an officer’s vehicle was “approaching 

from behind”. Id. Our court then stated, “[i]ndeed, perhaps the prudent driver 

should be more careful to maintain his lane in such a situation”, and held it could 

not conclude probable cause was lacking for the stop. Id.) 

Therefore, the district court erred in granting the motion to suppress by 

holding no reasonable law-enforcement officer would conduct a stop under these 

circumstances. This is the exact issue Whren resolved by holding an officer may 

conduct a stop where probable cause exists, 517 U.S. at 810; and probable cause 

to conduct a stop exists when law enforcement officers observe traffic violations, 

e.g., Khanalizadeh, 493 F.3d at 482. Although the Trooper only issued Rosales a 

warning citation for careless driving, it nevertheless was issued because the 

Trooper observed Rosales drive carelessly. Based on the third claimed offense, 

and pursuant to Mississippi’s careless-driving statute, the requisite probable 

cause existed for the stop. 

Along that line, and as discussed supra, in granting the suppression motion, 

the district court also addressed the Trooper’s subjective intentions as a trained 

highway law-enforcement officer and the suspicions that arose from such training. 

Although, in denying the Government’s motion to reconsider, the court expressly 

eschewed reliance on the Trooper’s subjective intentions, it proceeded to discuss 

the Trooper’s experienced-based suspicions and Rosales’ ethnicity as reasons for 

suppressing the evidence. As also discussed supra, this constituted error. Whren, 

517 U.S. at 813 (“Subjective intentions play no role in ordinary, probable-cause 

Fourth Amendment analysis.”); see also, e.g., Cole, 444 F.3d at 689 (test for trafficstop legality is objective).

For the foregoing reasons, the suppression order is REVERSED, and this 

matter is REMANDED to district court for further proceedings.

HAYNES, Circuit Judge, dissenting:

The majority opinion correctly notes that we review the district court’s 

factual findings for clear error and its legal conclusions de novo. See United 

States v. Jenson, 462 F.3d 399, 403 (5th Cir. 2006). However, the majority 

opinion fails to give appropriate deference to the district court’s credibility 

determinations and resulting factual findings and also incorrectly assesses 

Mississippi law. Viewed properly, the district court order did not commit 

reversible error in its order suppressing evidence. Accordingly, I respectfully 

dissent.

 We must review the district court’s findings of fact for clear error, only 

disregarding them when, “on the entire evidence[,] [this court] is left with a 

firm and definite conviction that a mistake has been committed.” United States 

v. Gomez-Moreno, 479 F.3d 350, 354 (5th Cir. 2007) (citation and internal

quotation marks omitted) (emphasis added); see United States v. Raney, 633 

F.3d 385, 389 (5th Cir. 2011) (“A factual finding is not clearly erroneous as long 

as it is plausible in light of the record as a whole.” (citation and internal 

quotation marks omitted)). When factual findings derive from live testimony 

and credibility determinations, district courts are afforded even more 

deference. See, e.g., United States v. Robinson, 741 F.3d 588, 594 (5th Cir. 

2014); United States v. Gibbs, 421 F.3d 352, 357 (5th Cir. 2005) (“‘One of the 

most important principles in our judicial system is the deference given to the 

finder of fact who hears the live testimony of witnesses because of his 

opportunity to judge the credibility of those witnesses.’” (quoting Louis v. 

Blackburn, 630 F.2d 1105, 1109 (5th Cir. 1980))). Finally, we “may affirm on 

any basis established by the record, considering the evidence presented at the 

suppression hearing in the light most favorable to the prevailing party.” 

United States v. Aguirre, 664 F.3d 606, 610 (5th Cir. 2011) (citations and 

12

 Case: 14-60149 Document: 00512837615 Page: 12 Date Filed: 11/14/2014

internal quotation marks omitted); United States v. Scroggins, 599 F.3d 433, 

440 (5th Cir. 2010) (citations and internal quotation marks omitted). 

Two pieces of evidence are relevant to the determination of the propriety 

of this stop and resultant findings: the trooper’s testimony and the videotape 

he recorded. The district court found the trooper not to be credible: it was “not 

convinced that the testimony of the trooper was credible.” Thus, we cannot 

reverse the district court based upon testimony of the trooper as the district 

court is entitled to make the credibility determinations based upon its live 

assessment of the witness. See Robinson, 741 F.3d at 594; Gibbs, 421 F.3d at

357. 

Turning to the video, it shows Rosales-Giron’s van driving close to the 

right-hand edge of the lane, but does not definitively show the van touching 

the fog line; it certainly does not show the van swerving within its lane or 

crossing the fog line. We should defer to the district court’s findings that “the 

only justification that this officer makes for stopping this particular car” was, 

as “the video shows[,] that while the trooper was up beside the van, the van 

didn’t swerve; simply moved over and happened to run onto the fog line.”1 

Accordingly, under a particularly deferential clear error standard, I am 

certainly not left with a firm and definite conviction that the district court 

erred in finding, at most, a “run onto the fog line.” 

Considering only this alleged violation as we are bound to do, it becomes 

clear that, at most, “while the trooper was up beside the van, the van didn’t 

swerve; simply moved over and happened to run onto the fog line.” (emphasis 

1 The district court appears to be referring to the first part of the video, from about 0 

to 10 seconds. At that point, the video shows the trooper’s car traveling very close to the 

centerline as the van gradually comes into view, with the van driving closer to the fog line 

and keeping a distance between itself and the trooper’s car as the trooper’s car drops behind 

the van.

added). The trooper admitted during the hearing that, during all of the 

violations he alleged, the van was only “on [the fog line]. I don’t know that [the 

van] crossed it, but [it] hit it.” Thus, we turn to the question of law: whether 

one instance of hitting or moving onto the fog line constitutes careless driving 

under Mississippi law. It does not. A careful reading of Mississippi case law 

interpreting the careless driving statute shows that simply bumping or hitting 

the fog line by itself does not suffice to justify a careless-driving finding; 

instead, all the cases involve additional conduct. See generally MISS. CODE 

ANN. § 63-3-1213.2 

Indeed, every single Mississippi case supporting a finding of careless 

driving involves more serious and imprudent conduct than bumping the fog 

line one time.3 Even in cases upholding traffic stops based on the most 

2 I disagree with the majority opinion’s suggestion that I need the support of a 

Mississippi case holding that bumping the fog line once does not justify a stop in order to 

affirm the district court’s conclusion that the stop was unreasonable under the Fourth 

Amendment. The touchstone of our Fourth Amendment analysis is reasonableness, 

considering how state law classifies the allegedly illegal conduct. See Ohio v. Robinette, 519 

U.S. 33, 39 (1996) (“We have long held that the touchstone of the Fourth Amendment is 

reasonableness. Reasonableness, in turn, is measured in objective terms by examining the 

totality of the circumstances.” (citations and internal quotation marks omitted)). When we 

give proper deference to the trial court’s factual findings, Rosales-Giron’s conduct included 

only one bump of the fog line. Since no Mississippi court has found a careless driving stop 

justified for just one bump of the fog line without additional conduct, I agree with the district 

court’s conclusion that it was objectively unreasonable for the trooper to stop Rosales-Giron’s 

van under the totality of the circumstances. 

3 See, e.g., Ludwig v. State, 122 So. 3d 1229, 1231–33 (Miss. Ct. App. 2013) (finding 

probable cause where a defendant drove so close to the edge of the road that “the mirror could

minimal conduct, drivers at least weaved or definitively crossed the fog line, 

rather than simply bumping it. See, e.g., Williams v. State, 126 So. 3d 85, 89 

(Miss. Ct. App. 2013) (finding reasonable suspicion justified a traffic stop 

where a vehicle “weave[d] out of [its] lane of traffic and across the fog line”); 

Tran v. State, 963 So. 2d 1, 13–14 (Miss. Ct. App. 2006) (holding officer had a 

reasonable basis to stop a motorist for “crossing the fog line” and that “failure 

to have regard for the width and use of the street by swerving off the side of the 

road or crossing the marker lines constitutes probable cause for a traffic stop”) 

(emphasis added), aff’d sub nom. Quang Thanh Tran v. State, 962 So. 2d 1237 

(Miss. 2007); Adams v. City of Booneville, 910 So. 2d 720, 721, 725 (Miss. Ct. 

App. 2005) (finding probable cause for a careless-driving stop in the totality of 

the circumstances, considering the defendant’s car was “traveling in the middle 

of two lanes of traffic” and “swerv[ing]” “around 2:30 a.m.” on “New Year’s 

Day”); Saucier v. City of Poplarville, 858 So. 2d 933, 934 (Miss. Ct. App. 2003) 

(finding probable cause where a vehicle decreased its speed, “bump[ed] the 

centerline,” then crossed “into the center lane and jerked . . . back into the right 

lane”). No Mississippi case validating a careless-driving traffic stop involves 

only the minimal conduct present here.4 

The majority opinion also cites a case for the proposition that under 

Mississippi law, “a court must reasonably interpret a wide range of factors when 

4 In Dominick v. State, the trial court credited an officer’s testimony that a car changed 

lanes, “bumped or simply rode the fog line,” and then changed lanes again, “bump[ing] the 

center line to the right” after changing lanes. 108 So. 3d 452, 456 (Miss. Ct. App. 2012) 

(internal quotation marks omitted). The Mississippi Court of Appeals acknowledged that the 

trial judge had credited the officer’s testimony, that video evidence proved unclear, and that 

nothing contradicted the officer’s testimony before affirming the trial court’s finding that the 

officer had probable cause to stop the vehicle. Id. In Martin v. State, a trooper observed a 

car swerve and drift over the fog line: the “vehicle went from point A to point B and right 

back. [It] didn’t [simply] drift over to the fog line.” 43 So. 3d 533, 535 (Miss. Ct. App. 2010) 

(internal quotation marks omitted). The Mississippi Court of Appeals thus upheld the trial 

court’s finding of probable cause. Id.

determining carelessness under the careless-driving statute.” See Henderson v. 

State, 878 So. 2d 246, 247 (Miss. Ct. App. 2004) (finding probable cause where a 

vehicle almost hit a curb, stopped at a stop sign, and then almost hit another curb 

in the early morning hours). No “wide-ranging” factors are present here: at most, 

there is one bump of the fog line. Cf. Saucier, 858 So. 2d at 934–35 (comparing 

case law and noting “there was not a one-time and brief drifting across the painted 

stripe separating lanes . . . but [] multiple intrusion[s] across the dividing stripe 

on the highway,” and that “[t]he frequency of the failure to maintain the proper 

lane suggests a greater degree of risk and carelessness,” as does crossing “into the 

lane for traffic going the opposite direction”). 

Although we employ de novo review of the legal question, determining 

what constitutes “due regard for the width . . . and use of the streets” and what it 

means to “drive[] any vehicle in a careless or imprudent manner” requires 

consideration of a wide range of factors, including some that are inherently based 

on factual findings. MISS. CODE ANN. § 63-3-1213; see also Henderson, 878 So. 2d 

at 247. In analogous contexts, we have allowed district courts to assess a 

defendant’s conduct in light of the pursuing officer’s actions. Here, the trooper’s 

vehicle was stationed alongside the van, potentially very close to the centerline. 

Our own case law shows that this court may account for the effect of an officer’s 

presence immediately behind or beside a defendant’s vehicle when analyzing 

that defendant’s driving behavior. Cf. United States v. Rivera-Gonzalez, 413 

F. App’x 736, 739–40 (5th Cir. 2011) (unpublished) (noting that “when the 

officer’s actions are such that any driver, whether innocent or guilty, would be 

preoccupied with his presence, then any inference that might be drawn from 

the driver’s behavior is destroyed,” and that even “abnormal turn-signaling 

might qualify as innocent” because “[e]ven an innocent driver wondering why

a Border Patrol car is following for several miles might forget to turn off a turn 

signal.” (citations and internal quotation marks omitted)).5

To the extent that the majority opinion concludes that the district court’s 

findings are unclear, the proper remedy is a remand for clarification, not 

reversal. See Sprint/United Mgmt. Co. v. Mendelsohn, 552 U.S. 379, 386, 388

(2008) (vacating with instructions to remand to the district court for 

clarification, holding that “[w]hen a district court’s language is ambiguous, as 

it was here, it is improper for the court of appeals to presume that the lower 

court reached an incorrect legal conclusion. A remand directing the district

court to clarify its order is generally permissible and would have been the 

better approach in this case”); cf. Gomez-Moreno, 479 F.3d at 354. As it stands, 

I conclude that the record and the district court’s findings are sufficiently clear 

to distinguish this case from every other Mississippi case that has condoned a 

traffic stop for careless driving based on a driver’s interaction with the fog line

(and more). Reasonably interpreting carelessness and what it means to give 

due regard for the width and use of the road in light of a wide range of factors, 

I disagree with holding that an officer can stop a van in Mississippi simply for 

bumping the fog line one time. Such a holding to reverse a district court

expands the definition of careless driving under § 63-3-1213 beyond the 

boundary Mississippi courts have drawn.

5 Although Rivera-Gonzalez is not “controlling precedent,” it “may be [cited as] 

persuasive authority.” Ballard v. Burton, 444 F.3d 391, 401 n.7 (5th Cir. 2006) (citing 5TH 

CIR. R. 47.5.4). For cases where this court has taken account of an officer’s presence in 

examining a defendant’s driving behavior, see also United States v. Zapata-Ibarra, 212 F.3d 

877, 882–83 (5th Cir. 2000) (finding that deceleration of a vehicle and its swerving within its 

lane only slightly supported reasonable suspicion when the vehicle did so in reaction to a 

rapidly-approaching police car that had activated its high-beam lights); United States v. 

Jones, 149 F.3d 364, 370–71 (5th Cir. 1998) (finding that a driver’s act in drifting off the 

roadway did not give rise to reasonable suspicion in the totality of the circumstances, because 

the driver was glancing back at the officer, who was tail-gaiting the driver).

No. 14-60149

Because the district court did not err in concluding that the trooper 

lacked lawful justification to stop Rosales-Giron’s van,6 I would affirm the 

district court’s suppression of evidence. Accordingly, I respectfully dissent

from the judgment of the court reversing the district court.

6 Of course, I agree with the majority opinion that the trooper’s subjective intentions 

in making the traffic stop play no part in the probable cause analysis and that the district 

court should not have discussed them. See Whren v. United States, 517 U.S. 806, 813 (1996) 

(“Subjective intentions play no role in ordinary, probable-cause Fourth Amendment 

analysis.”); United States v. Cole, 444 F.3d 688, 689 (5th Cir. 2006). Again, if we are 

concerned about whether this mention of subjective intent affected the district court’s 

conclusions, we should remand, not reverse. See Sprint/United Mgmt. Co., 552 U.S. at 386, 

388.
