 MEMORANDUM OPINION* BY 

v. Record No. 1813-08-1 JUDGE RUDOLPH BUMGARDNER, III 

JULY 21, 2009 

COMMONWEALTH OF VIRGINIA 

FROM THE CIRCUIT COURT OF THE CITY OF NEWPORT NEWS 

H. Vincent Conway, Jr., Judge 

 Sherman C. Smith, Assistant Public Defender, for appellant. 

 Gregory W. Franklin, Assistant Attorney General (William C. Mims, 

Attorney General, on brief), for appellee. 

 Monae Chanta Savage appeals her conviction of reckless driving by speeding 70 miles 

per hour in a 45 miles-per-hour zone, Code § 46.2-862. She maintains the evidence was 

insufficient to prove the speed of her vehicle. Finding the argument is without merit, we affirm. 

 The arresting officer paced the defendant’s car for two-tenths of a mile at 70 miles per 

hour. The posted speed limit was 45 miles per hour. The defendant did not object to the 

evidence of her speed. When the Commonwealth rested its case, the defendant moved to strike 

the evidence. She argued it was insufficient to prove her speed because pacing was not a method

for determining speed listed in Code § 46.2-882.1 The trial court denied the motion. The 

defendant presented no evidence. 

 By not objecting to the admission of the officer’s testimony of his pace of the defendant’s 

car, it became evidence of the speed of the car. It was sufficient to prove guilt, and the trial court 

properly denied the motion. 

 Code § 46.2-882 is a statute permitting the admissibility of evidence. It is not a statute of 

exclusion. It currently sanctions four types of scientific evidence that determine speed by 

eliminating the need to prove that the underlying scientific principle or technique of the 

measuring device is reliable. The statute was first enacted in 1954, 1954 Va. Acts, c. 385, to 

sanction Doppler shift radar as a scientifically valid technique for measuring speed. 

Subsequently, the statute has been amended as other techniques were adopted for measuring the 

speed of highway vehicles. 

Nothing in Code § 46.2-882 suggests the statute is meant to limit the means for proving 

speed. The statute itself states that speed “may” be determined by the enumerated means. “The 

word ‘may’ is prima facie permissive, importing discretion, but the courts construe it to be 

mandatory when it is necessary to accomplish the manifest purpose of the Legislature.” C. & O.

 In pertinent part, Code § 46.2-882 provides: 

The speed of any motor vehicle may be determined by the use of (i) a laser 

speed determination device, (ii) radar, (iii) a microcomputer device that is 

physically connected to an odometer cable and both measures and records 

distance traveled and elapsed time to determine the average speed of a 

motor vehicle, or (iv) a microcomputer device that is located aboard an 

airplane or helicopter and measures and records distance traveled and 

elapsed time to determine the average speed of a motor vehicle being 

operated on highways within the Interstate System of highways as defined 

in § 33.1-48. The results of such determinations shall be accepted as 

prima facie evidence of the speed of such motor vehicle in any court or 

legal proceeding where the speed of the motor vehicle is at issue.

always been an acceptable method of the speed of a car. Shrader v. Commonwealth, 2 Va. App. 

287, 291, 343 S.E.2d 375, 378 (1986). The statute does not prevent the Commonwealth from 

proving a vehicle’s speed by other methods. 

One of the easiest methods is pacing. This involves accurately determining the speed of 

one vehicle while proceeding at a constant distance from a second vehicle. If the distance 

between the two vehicles remains constant, the speed of the second vehicle must be the same as 

the known speed of the first vehicle. Code § 46.2-9422 clearly contemplates the use of pacing as 

a method of determining a vehicle’s speed by authorizing the admission of calibration tests to 

prove the accuracy of an arresting officer’s speedometer. 

The need to determine the speed of automobiles began in the early 1900s. The General 

Assembly enacted the first speed limit statute in 1904. 1902-1904 Va. Acts, c. 34. Radar came 

into use in the early 1950s. Very soon, case law and statutory law accepted the scientific 

principle involved and eliminated the need of expert testimony to prove the scientific basis of the 

technique. As noted, Virginia enacted current Code § 46.2-882 to permit radar in 1954. See 1 

McCormick on Evidence 839-45 (Kenneth S. Broun ed., 6th ed. 2006). 

The speed of vehicles was proven in court long before science provided radar as a 

method. Any means that would accurately measure the distance a car traveled and the time it 

took for it to do so would provide proof of the rate, or speed, at which it traveled. Indeed, the

 Code § 46.2-942 provides: 

In the trial of any person charged with exceeding any maximum speed 

limit in the Commonwealth, the court shall receive as evidence a sworn 

report of the results of a calibration test of the accuracy of the speedometer 

in the motor vehicle operated by the defendant or the arresting officer at 

the time of the alleged offense. The report shall be considered by the 

court or jury in both determining guilt or innocence and in fixing 

punishment.

earliest method of using a stopwatch to time a vehicle over a known distance has come into 

renewed use with traffic patrolling by airplane. Id.

 The omission of pacing from the methods for determining speed that are enumerated in 

Code § 46.2-882 does not in any way invalidate it as an appropriate means of proving the speed 

of a vehicle. Accordingly, we affirm the conviction. 

 Affirmed.
