IN THE SUPREME COURT OF TENNESSEE 

AT KNOXVILLE

May 27, 2009 Session Heard in Cookeville1

STATE OF TENNESSEE v. JERRY LEE HANNING

Appeal by Permission from the Court of Criminal Appeals

Criminal Court for Loudon County

No. 10914 E. Eugene Eblen, Judge

No. E2006-02196-SC-R11-CD - Filed October 20, 2009

This appeal involves the detention and questioning of the driver of a truck tractor and trailer based

upon an anonymous tip of reckless driving from a citizen. A police officer received a dispatch that

a caller had reported a black “18-wheeler” bearing a “Smith Brothers” logo was being driven

recklessly in a northbound direction on the interstate and had just exited at the Highway 72 ramp.

The police officer was in a parking lot very close to the exit ramp at the time he received the call.

He responded immediately and observed a black “semi-truck” parked in the emergency lane of the

northbound exit ramp. The officer turned his blue lights on, drove down the ramp, and pulled in

front of the truck. After observing a Smith Transport logo on the door of the truck tractor,

questioning the driver, and administering field sobriety tests, the officer arrested the driver for

driving under the influence. The driver entered a conditional guilty plea to driving under the

influence and reserved the certified question of whether the warrantless detention and questioning

of the driver violated the Fourth Amendment to the United States Constitution and Article I, Section

7 of the Constitution of the State of Tennessee. We hold that in this case the anonymous tip

reporting reckless driving indicated a sufficiently high risk of imminent injury or death to members

of the public to warrant immediate intervention by law enforcement officials and justified the brief

investigatory stop because the offense was reported at or near the time of its occurrence, and the

report indicated that the caller was witnessing an ongoing offense; the report provided a detailed

description of the truck, its direction of travel and location; and the investigating officer verified

these details within moments of the dispatch reporting the tip.

OPINION

Facts and Procedural Background

On November 15, 2003, at approximately 9:30 p.m., Sergeant Kent Russell of the Loudon

Police Department received a radio dispatch that an anonymous caller had reported a recklessly

driven truck headed north on Interstate 75. The calleridentified the vehicle as a black “18-wheeler”2

with “1-800-GoSmith” or “Go Smith Brothers” on the back and stated that the truck had exited at

the Highway 72 exit ramp. 

When Sergeant Russell received the dispatch, he was in the parking lot of a McDonald’s

restaurant located about one hundred and fifty yards from the top of the Highway 72 exit ramp. He

immediately drove to the exit ramp where he observed a black truck tractor and trailer with its

parking lights on parked in the emergency lane, facing the top of the ramp. Sergeant Russell

activated his emergency blue lights, drove his patrol car down the ramp against the flow of traffic,

and parked with the front of his vehicle very close to the front of the truck. Sergeant Russell walked

up to the truck’s door, which was emblazoned with an eagle image and the words “Smith” and

“transport,” and requested the truck’s driver, Jerry Lee Hanning, to step out of the truck. After Mr.

Hanning complied with Sergeant Russell’s request, Sergeant Russell asked him if he had been

drinking, administered various field sobriety tests, arrested him for driving under the influence, and

transported him to a hospital for a blood alcohol test.

In October of 2004, the Loudon County grand jury returned an indictment charging Mr.

Hanningwith driving under the influence (“DUI”) in violation of Tennessee Code Annotated section

55-10-401 and with possession of an open container of an alcoholic beverage in violation of 3

Tennessee Code Annotated section 55-10-416. Mr. Hanning filed a motion to suppress all evidence

4

obtained as a result of the detention of himself and his vehicle upon the ground that Sergeant Russell

 We take judicial notice that “18-wheeler” and “semi-truck” are colloquial expressions for a truck tractor and

2

trailer.

“It is unlawful for any person to drive or to be in physical control of any automobile or other motor driven

3

vehicle on any of the public roads and highways of the state . . . , while: (1) Under the influence of any intoxicant . . .

; or (2) The alcohol concentration in the person’s blood or breath is eight-hundredths of one percent (.08 %) or more.”

Tenn. Code Ann. § 55-10-401(a)(1)-(2) (2008). 

“No driver shall consume any alcoholic beverage or beer or possess an open container of alcoholic beverage

4

or beer while operating a motor vehicle in this state.” Tenn. Code Ann. § 55-10-416(a)(1) (2008).

2
lacked reasonable suspicion or probable cause and therefore violated the search and seizure

provisions of the state and federal constitutions. The trial court denied the motion to suppress.

After the denial of his motion to suppress, Mr. Hanning entered into a conditional plea

agreement with the State. In exchange for a conditional plea of guilty to the DUI charge, the open

container charge was dismissed, and he was sentenced to eleven months, twenty-nine days

incarceration, suspended upon his service of three days in jail and payment of fines and costs. This

plea reserved and certified for appeal the question presented in the motion to suppress of “whether

the warrantless questioning and detention of Mr. Hanning violated the Fourth Amendment to the

United States Constitution and Article I, Section 7 of the Constitution of the State of Tennessee.”

This question was certified for appeal pursuant to Rule 37(b)(2) of the Tennessee Rules of Criminal

Procedure by order of the trial court. 5

The Court of Criminal Appeals affirmed the trial court’s denial of the motion to suppress and

found that Sergeant Russell had reasonable suspicion that the truck was the same one that the caller

had identified as being driven recklessly, based upon the facts that when Sergeant Russell received

the dispatch he was in close proximity to the specified exit ramp, he immediately proceeded to the

ramp, and found a black truck tractor and trailer sitting as if it had exited I-75, as stated by the caller.

The Court of Criminal Appeals further found that, based upon Sergeant Russell’s reasonable

suspicion that Mr. Hanning had been driving recklessly, he properly questioned Mr. Hanning and

administered field sobriety tests. Based on the results of these actions, the Court of Criminal

Appeals also found that the officer had probable cause to arrest Mr. Hanning for driving under the

influence. We granted Mr. Hanning’s application for permission to appeal.

Analysis

As noted, the certified question reserved for appeal was “whether the warrantless questioning

and detention of Mr. Hanning violated the Fourth Amendment to the United States Constitution and

Article 1, Section 7 of the Constitution of the State of Tennessee.” We determine that under the facts

of this case, the warrantless detention was valid because it was supported by reasonable suspicion

that Mr. Hanning had committed a crime.

Although this case comes to us on appeal as a certified question of law under Tenn. R. Crim.

P. 37(b)(2), we review it under the same standard as an appeal from a judgment denying a motion

to suppress. See State v. Nicholson, 188 S.W.3d 649, 656 (Tenn. 2006). The “trial court’s findings

of fact in a suppression hearing will be upheld unless the evidence preponderates otherwise.” State

v. Odom, 928 S.W.2d 18, 23 (Tenn. 1996). Furthermore, although “[t]he party prevailing in the trial

court is entitled to the strongest legitimate view of the evidence adduced at the suppression hearing

Tenn. R. Crim. P. 37 (b)(2)(A)(i) provides that a defendant in a criminal proceeding may appeal from any

5

judgment of conviction “on a plea of guilty . . . if . . . the judgment of conviction or other document to which such

judgment refers that is filed before the notice of appeal, contains a statement of the certified question of law that the

defendant reserved for appellate review.” 

3
as well as all reasonable and legitimate inferences that may be drawn from that evidence,” id., the

burden remains on the State to prove that a warrantless search was constitutionally permissible.

Nicholson, 188 S.W.3d at 656-57; State v. Henning, 975 S.W.2d 290, 298 (Tenn. 1998). We review

questions of law de novo. State v. Day, 263 S.W.3d 891, 900 (Tenn. 2008).

The Fourth Amendment to the Constitution of the United States, applicable to the states

through the Fourteenth Amendment as recognized in Mapp v. Ohio, 367 U.S. 643, 650 (1961),

provides:

The right of the people to be secure in their persons, houses, papers, and effects,

against unreasonable searches and seizures, shall not be violated, and no warrants

shall issue, but upon probable cause, supported by oath or affirmation, and

particularly describing the place to be searched, and the persons or things to be

seized.

Similarly, Article I, Section 7 of the Tennessee Constitution provides:

That the people shall be secure in their persons, houses, papers and possessions, from

unreasonable searches and seizures; and that general warrants, whereby an officer

may be commanded to search suspected places, without evidence of the fact

committed, or to seize any person or persons not named, whose offences are not

particularly described and supported by evidence, are dangerous to liberty and ought

not to be granted.

Three categories of police-citizen interaction have been judicially designated: (1) full-scale

arrest, which must be supported by probable cause, see Brown v. Illinois, 422 U.S. 590, 598 (1975);

State v. Ferrante, 269 S.W.3d 908, 913 (Tenn. 2008); (2) brief investigatory detention, which must

be supported by reasonable suspicion of criminal activity, see Terry v. Ohio, 392 U.S. 1, 27 (1968);

State v. Williams, 185 S.W.3d 311, 315 (Tenn. 2006); and (3) brief police-citizen encounter that

requires no objective justification, see Florida v. Bostick, 501 U.S. 429, 434 (1991); State v. Daniel,

12 S.W.3d 420, 424 (Tenn. 2000). The case before us involves a brief investigatory detention, and

accordingly, we must determine whether at the time Mr. Hanningwas detained, Sergeant Russell had

a reasonable suspicion that Mr. Hanning had committed a crime.

We have previously noted that a seizure or detention occurs when “‘in view of all of the

circumstances surrounding the incident, a reasonable person would have believed that he was not

free to leave.’” Williams, 185 S.W.3d at 316 (quoting United States v. Mendenhall, 446 U.S. 544,

554 (1980)). Ordinarily, when an officer turns on his blue lights, the officer has initiated a detention.

See State v. Pulley, 863 S.W.2d 29, 30 (Tenn. 1993). However, in some instances, an officer’s

activation of his or her emergency blue lights will not constitute a detention, such as when the officer

turns on the emergency lights for reasons of safety. See Williams, 185 S.W.3d at 318. While it is

arguable that Sergeant Russell initially activated his blue lights as a safety measure, given that he

was driving down the exit ramp against the flow of traffic, the parties have agreed that Mr. Hanning

4
and his truck were detained when, with its blue lights flashing, Sergeant Russell pulled his patrol car

very close to the front of Mr. Hanning’s truck. A reasonable person in Mr. Hanning’s place would

have believed he was not free to leave when the patrol car was parked in front of the truck, blocking

its exit. 

Having established the moment of detention, we must next determine whether the detention

was justified by reasonable suspicion of criminal activity. In determining whether an investigatory

detention is based upon reasonable suspicion, we engage in a “fact-intensive and objective analysis,”

reviewing the record for “specific and articulable facts, that the defendant had committed, or was

about to commit, a criminal offense.” See id. at 318-19. Reasonable suspicion must be supported

by something more than the officer’s “inchoate and unparticularized suspicion or ‘hunch.’” Day,

263 S.W.3d at 902 (quoting Terry, 392 U.S. at 27). However, “‘reasonable suspicion can be

established with information that is different in quantity or content than that required to establish

probable cause’” and “can arise from information that is less reliable than that required to show

probable cause.” Id. at 903 (quoting Pulley, 863 S.W.2d at 32).

When information is received from an anonymous informant, as occurred in the instant

matter, there is an enhanced concern as to whether the information is reliable or whether it was

fabricated. State v. Wilhoit, 962 S.W.2d 482, 487 (Tenn. Crim. App. 1997). Thus, in order to

ensure reliability, before a motor vehicle can be validly detained based upon information received

from an anonymous informant, there must be a showing of both 1) the basis of the informant’s

knowledge of the conveyed information and 2) the informant’s credibility. Day, 263 S.W.3d at 903

(citing Pulley, 863 S.W.2d at 31). The difficulty in utilizing this two-prong test to assess the

reliability of a tip received from an informant whose identity is unknown is readily apparent.

However, any deficiencies in demonstrating reliability based upon this test can be cured by an

investigatingofficer’sindependent corroboration of the anonymouslyprovided information.Wilhoit,

962 S.W.2d at 487. 

In the case before us, we first consider whether the basis of the caller’s knowledge and the

caller’s credibility were established in accord with the two-prong test for reliability. While the

record does not show the caller’s basis of knowledge, we have noted that “[w]hen an informant

reports an incident at or near the time of its occurrence, a court can often assume that the report is

first-hand, and hence reliable.” Pulley, 863 S.W.2d at 32. We have further held that this

contemporaneity of the caller’s observation and the call, coupled with an officer’s verification of

details of the caller’s observations shortly after receiving the call, can be sufficient to satisfythe basis

of knowledge prong of our inquiry. Wilhoit, 962 S.W.2d at 487-88. In this case, the anonymous

caller reported that a black “18-wheeler” was being driven recklessly on the interstate and had taken

the Highway 72 exit. The call suggested that the caller was reporting the reckless driving as it

occurred. Within mere minutes of receiving the dispatch, Sergeant Russell confirmed that there was

a truck matching the general description given by the caller at the location described by the caller.

The confirmation of this information in close proximity to its receipt was sufficient to demonstrate

the caller’s basis of knowledge. See id. at 488. 

5
While the anonymity of the caller precluded direct verification of the caller’s credibility,

Sergeant Russell’s independent corroboration of certain details provided by the caller, specifically

the type of vehicle (truck tractor and trailer), its color (black), its location (Highway 72 exit ramp),

and its direction of travel (northbound), was sufficient to satisfythe credibilityprong of the reliability

inquiry. See id. Furthermore, when Sergeant Russell observed the truck, it was parked in the 6

emergency lane of the exit ramp. While this was not a statutory offense at the time, it was a

7

sufficiently unusual circumstance to arouse Sergeant Russell’s suspicion that the truck was the one

reported by the caller as having been driven recklessly. 

Mr. Hanning asserts that Sergeant Russell did not personally observe the truck being driven

recklessly and, citing Florida v. J.L., 529 U.S. 266 (2000), argues that Sergeant Russell’s

corroboration of details observable or available to anyone did not establish reasonable suspicion. In

Florida v. J.L., the United States Supreme Court held that an anonymous caller’s report that a suspect

at a specific bus stop was carrying a concealed gun did not create reasonable suspicion sufficient to

justify the suspect being stopped and frisked by law enforcement officers. The Court indicated that

the anonymous caller’s failure to provide predictive information about the subject’s future

movements left the police without any means to confirm that the informant had inside knowledge

about the subject that would have lent credibility to the caller’s charge that the defendant was

engaged in criminal activity. 529 U.S. at 272. We find the circumstances of the instant case to be

distinguishable from the facts in Florida v. J.L. in several ways. 

First, a report of readily observable evidence of reckless driving carries a higher degree of

inherent reliability than does a report of a concealed weapon. The basis of the tipster’s knowledge

is apparent when the reported criminal activity is open to observation by the general public, whereas

the basis of the tipster’s knowledge of a concealed crime is unknown, absent proof of inside

information supporting the allegation. See Bloomingdale v. State, 842 A.2d 1212, 1219 (Del. 2004).

Furthermore, when a tipster seeks to report the location of a reckless driver at the time the reckless

driving is observed or shortly thereafter, the tipster has a very brief amount of time to contact the

police, and the likelihood that the allegation is fabricated is proportionately diminished. See id. at

As noted, the caller also described the truck as having “1-800-GoSmith” or “Go Smith Brothers” on the back.

6

While Sergeant Russell observed the words “Smith” and “transport” on the door of Mr. Hanning’s truck, he did not make

this observation until after the detention was complete, and therefore corroboration of this aspect of the information

provided by the caller could not provide further justification for the investigatory stop.

Effective April 7, 2008, subsection (c) was added to Tennessee Code Annotated section 55-8-158 and provides

7

in pertinent part as follows:

[N]o person shall stop, park or leave any motor vehicle, whether attended or

unattended, upon the paved or unpaved portions of any entrance or exit ramp of any

highway; provided, that a driver of a motor vehicle that has become disabled may

leave the vehicle on an entrance or exit ramp until such time as the disabled motor

vehicle can be repaired or towed, as long as the vehicle is not obstructing the

passage of other motor vehicles. Furthermore, the department may take into

consideration an emergency situation or compliance with federal laws. Tenn. Code

Ann. § 55-8-158(c) (2008). 

6
1220. By contrast, a tipster reporting a concealed weapon is not subject to such time restrictions.

And finally, the relatively limited amount of time available to report the location of a moving vehicle

also diminishes the possibility that the tip merely constitutes an attempt by the tipster to employ law

enforcement officials for the purpose of harassment. See id. Logistically, but for the corroboration

requirements imposed bythe Court in Florida v. J.L., it would be a simple matter to fabricate a report

of a concealed weapon that would expose an individual to a stop and frisk. However, in order to use

the police for harassment by falsely reporting that an individual is driving recklessly, the tipster

would be required to know not only that the person he seeks to harass is driving a particular vehicle

at a specific time and location, but also that at the time the report is made, an officer will be in close

enough proximity to the subject to promptly execute a stop of the vehicle. Given the intricacies and

improbabilities that would be involved in seeking to harass another by a report of reckless or erratic

driving, it seems highly unlikely that such a report will have been fabricated for that purpose. See

Bloomingdale, 842 A.2d at 1220 (concluding that, because reporting erratic driving “is such an

intricate, improbable, and imprecise method of harassing another,” the risk of a tip being falsified

by an informant is “significantly reduced”). 

 

Second, the level of intrusion presented by the actions of law enforcement officials in the two

cases is different. In Florida v.J.L., the stop and frisk conducted by the officers in the federal case

entailed physical contact between the officers and the suspect, whereas the intervention in this case

initially amounted to a brief detention and did not entail physical contact between Sergeant Russell

and Mr. Hanning. See State v. Boyea, 765 A.2d 862, 868 (Vt. 2000) (recognizing that the liberty

interest at stake in a brief motor vehicle stop does not rise to the level that confronted the Court in

Florida v. J.L.); see also United States v. Wheat, 278 F.3d 722, 737 (8th Cir. 2001) (stating that

investigatory stop of motor vehicle is “considerably less invasive, both physically and

psychologically, than the frisk on a public corner that was at issue in [Florida v.] J.L.”).

Finally, and most importantly, the degree of danger and urgency for immediate action that

confronted the officers in Florida v. J.L. was much lower than that confronting Sergeant Russell in

this case. A report that a vehicle is being driven recklessly or erratically suggests that the driver may

be under the influence of alcohol or drugs, see State v. Rutzinski, 623 N.W.2d 516, 526 (Wis. 2001)

(“Erratic driving is one possible sign of intoxicated use of a motor vehicle.”), fatigued, or in physical

distress and therefore incapable of controlling his or her vehicle. While a concealed weapon does

not of itself present an imminent danger of harm to the public, a truck driven recklessly does present

such a danger. Although the truck was parked at the moment it was located by Sergeant Russell, it

could have been moving and back on the interstate in a matter of seconds, and we do not believe that

Sergeant Russell was obligated to wait until the truck was back on the interstate and moving to

confirm the report of reckless driving. Had he done so, the first indication that the caller’s report of

reckless driving was correct might well have been a collision between the truck and another vehicle,

resulting in injury or death to Mr. Hanning and/or other members of the public. In Florida v. J.L.,

the Court acknowledged that under some circumstances, such as where a person is reported to be

carrying a bomb, the danger alleged by an anonymous caller might be so great that some lesser

indicia of reliability would be sufficient to justify a frisk. 529 U.S. at 273-74. A truck tractor and

trailer being driven recklessly on the interstate is sufficiently analogous to a bomb to warrant prompt

7
intervention and investigation by law enforcement officials. See Boyea, 765 A.2d at 867 (stating that

“a drunk driver is not at all unlike a ‘bomb,’ and a mobile one at that.”); accord Rutzinski, 623

N.W.2d at 526.

Mr. Hanning also relies on State v. Coleman, 791 S.W.2d 504 (Tenn. Crim. App. 1989), in

support of his argument that Sergeant Russell lacked reasonable suspicion to justify a detention. In

Coleman, an informant advised law enforcement officials that at a specified time, the subject in a

car of a particular color, model, and make would be transporting marijuana on Highway 431 to a

location on Washington Road in Robertson County. At the time specified by the caller, a deputy

located a car matching the description traveling on Highway 431 toward Robertson County. After

following the vehicle for a brief time, the deputy initiated a stop, searched the vehicle with the

driver’s consent, and discovered several pounds of marijuana. The Court of Criminal Appeals held

that the stop was invalid because the informant’s credibility and basis of knowledge were not

sufficiently established by the deputy’s independent corroboration of the information provided. In

so holding, the Court noted that law enforcement officials failed to make any inquiry as to the

driver’s identity or her reputation with respect to the use or sale of illegal drugs. Coleman, 791

S.W.2d at 506. We find Coleman to be distinguishable from the present case. In Coleman, although

the informant’s identitywas apparently known, law enforcement officials failed to make any attempt

to verify the informant’s credibility. Coleman is also distinguishable from the matter now before us

in that the criminal activityreported by the callerin that case (transportation of drugs) did not present

an imminent threat of harm to the public. 

In the wake of the United States Supreme Court’s decision in Florida v. J.L. and consistent

with our above analysis differentiating that case from the present one, one United States Circuit

Court of Appeals and a multitude of state jurisdictions have ruled that an investigatory stop may be

initiated on the basis of an anonymous report of erratic, reckless or drunk driving, even without

corroboration of any criminal activity by law enforcement officials. See Cottrell v. State, 971 So.2d

735, 745-46 (Ala. Ct. Crim. App. 2006); People v. Wells, 136 P.3d 810, 815-16 (Cal. 2006);

Bloomingdale, 842 A.2d at 1219-20; State v. Prendergast, 83 P.3d 714 (Haw. 2004); State v.

Walshire, 634 N.W.2d 625, 630 (Iowa 2001); State v. Crawford, 67 P.3d 115, 119-20 (Kan. 2003);

State v. Barras, No. 2009 KA 0014, 2009 WL 1717166, at *4-5 (La. App. 1. Cir. June 19, 2009);

State v. Sousa, 855 A.2d 1284, 1290 (N.H. 2004); State v. Contreras, 79 P.3d 1111, 1117-18 (N.M.

Ct. App. 2003); People v. Jeffery, 2 A.D.3d 1271, 1271 (N.Y. App. Div. 2003); Boyea, 765 A.2d

at 868; Wheat, 278 F.3d at 729. We find guidance in all of these cases in reaching a conclusion in

the present matter. We are also guided in our decision by specific factors recognized by this Court

in State v. Pulley, 863 S.W.2d 29, 33 (Tenn. 1993).

In Pulley, the police received two anonymous reports indicating that a man driving a yellow

Ford L.T.D. in a specified trailer park was armed with a shotgun and was “supposed to shoot

someone.” 863 S.W.2d at 29. The police found the subject in a vehicle matching the description,

not at the named trailer park, but parked at a nearby gas station. The investigating officer testified

that when he arrived at the gas station, he turned on his blue lights, approached the subject’s car, and

asked him to step out, at which time he saw a shotgun on the car’s floorboard. He arrested the

8
subject on several charges that included possessing various weapons with the intent to go armed and

driving under the influence. Both the trial court and the Court of Criminal Appeals agreed that the

weapons and the results of a blood alcohol test should be suppressed, presumably upon grounds that

the investigating officer did not have reasonable suspicion of criminal activity to justify the stop. We

reversed upon consideration of the following three factors: “‘(i) the public interest served by the

seizure, (ii) the nature and scope of the intrusion, and (iii) the objective facts upon which the law

enforcement officer relied in light of his knowledge and experience.’” Pulley, 863 S.W.2d at 34

(quoting Mendenhall, 446 U.S. at 561). We determined that 1) the stop served the public’s interest

in the prevention of violent crime; 2) the scope of what was intended to be a temporary stop was

minor; 3) the timely nature of the anonymous report indicating that the caller was an eyewitness

verified the caller’s basis of knowledge; and 4) the corroboration of many of the details described

by the caller “provided some basis to believe the informant was credible.” Id. at 34. We concluded

that “given the threat of violence, the police had ‘specific and articulable facts’ to warrant the

investigatory stop,” id., and we recognized “the need for immediate police action in response to

serious threats of harm,” stating that the “reliability of the informant’s tip is not the only determinant

of the reasonableness of the stop. The content of the tip is also a crucial factor and, in particular, the

level of danger that the tip reveals,” id. at 32. 

Although Pulley did not involve a report of reckless driving, we believe that a report of a

truck tractor and trailer being driven recklessly on the interstate poses a sufficiently high degree of

threat of imminent hazard to warrant prompt investigation by law enforcement officials. With

specific reference to the three factors designated in Pulley, we conclude that Sergeant Russell’s

detention of Mr. Hanning served the public’s interest in the prevention of reckless driving; the scope

of what was intended to be a temporary stop was minor; and in light of these considerations, the

caller’s basis of knowledge and credibility were sufficiently corroborated by Sergeant Russell to

establish reliability. Taking into account these three factors and bearing in mind the high degree of

danger presented by the anonymous tip, we hold that the warrantless detention of Mr. Hanning and

his truck were justified upon reasonable suspicion of criminal activity. 

As we indicated in Pulley, an officer’s action should be evaluated “in light of one’s reaction

had [the officer] failed to act.” Id. at 33. In this case, had Sergeant Russell refrained from detaining

Mr. Hanning and allowed him to resume driving, either Mr. Hanning or another member of the

public may well have been killed or injured. We emphasize the importance of this consideration in

our decision herein. As we have noted above, reckless or erratic driving indicates that the driver may

be impaired as the result of an intoxicant. Recent statistics of the National Highway Transportation

Safety Administration show that in 2007 approximately 13,000 people were killed by drunk drivers

nationally, and the citizens of Tennessee are not exempt from this ongoing tragedy. The imminent 8

danger presented by drunk driving and the public’s interest in eliminating this problem are obvious

and indisputable.

9
In holding that detention was justified in the present case, we do not intend to imply that the

extent of corroboration provided by Sergeant Russell will, as a general matter, be sufficient to

establish reliabilityof anonymouslyprovided information, but onlythat such degree of corroboration

can be sufficient to establish such reliabilitywhen independent corroboration of the reported criminal

activity is not feasible because there is a high risk of imminent injury or death equivalent to the risk

posed by a truck tractor and trailer being recklessly driven on the interstate. Furthermore, we are

compelled to emphasize that the content of the tip is of critical significance. Thus, the degree of

corroboration that was sufficient to establish reliability in this case may not be sufficient where the

nature of the activity reported and any associated imminent danger cannot be reasonably inferred

from the information conveyed by the informant. See State v. Day, 263 S.W.3d 891 (Tenn. 2008)

(holding that officer lacked reasonable suspicion to stop suspect where stop was based solely on

anonymous driver flashing her lights, waving her arms, and pointing at suspect’s vehicle). 

Having justifiably detained Mr. Hanning based upon reasonable suspicion of criminal

activity, Sergeant Russell approached the door of the truck where he observed the Smith logo and

properly asked Mr. Hanning to step from the truck. See State v. Berrios, 235 S.W.3d 99, 106 (Tenn.

2007) (citing Pennsylvania v. Mimms, 434 U.S. 106, 109-11 (1977) (holding that once a vehicle has

been lawfully detained, an officer may, as a matter of course, order the driver to step out of the

vehicle)). Thereafter, Sergeant Russell properly administered field sobriety tests, establishing

probable cause to arrest Mr. Hanning for driving under the influence. 

In summary, we hold that in this case the anonymous tip reporting reckless driving suggested

a sufficiently high risk of imminent injury or death to members of the public to warrant immediate

intervention by law enforcement officials and justified the brief investigatory stop by Sergeant

Russell because the offense was reported at or near the time of its occurrence, and the report

indicated that the callerwaswitnessing an ongoing offense; the report provided a detailed description

of Mr. Hanning’s truck, its direction of travel and location; and Sergeant Russell verified these

details within moments of the dispatch reporting the tip. 

Conclusion

For the foregoing reasons, on the certified question presented, we hold that Sergeant

Russell’s warrantless detention of Mr. Hanning and his truck was valid because it was supported by

reasonable suspicion that Mr. Hanning had committed or was about to commit a crime. Accordingly,

we affirm the judgment of the Court of Criminal Appeals. The costs of this appeal are assessed to

Jerry Lee Hanning, and his surety, for which execution may issue if necessary.
