Approved March 17, 1954
Be it enacted by the General Assembly of Virginia:

1. That the Code of Virginia be amended by adding a section numbered
46-215.2 as follows:

§ 46-215.2. (a) The speed of any motor vehicle may be checked by
the use of radiomicro waves or other electrical device. The results of
such checks shall be accepted as prima facie evidence of the speed of such
motor vehicle in any court or legal proceedings where the speed of the
motor vehicle is at issue.

The driver of any such motor vehicle may be arrested without a
warrant under this section provided the arresting officer is in uniform or
displays his badge of authority; provided that such officer has observed
the recording of thespeed of such motor vehicle by the radiomicro waves
or other electrical device, or has received a radio message from the officer
who observed the speed of the motor vehicle recorded by the radiomicro
waves or other electrical device; provided in case of an arrest based on
such a message that such radio message has been dispatched immediately
after the speed of the motor vehicle was recorded and furnished the
license number of the vehicle and the recorded speed to the arresting
officer.

(c) No operator of a motor vehicle may be arrested under this sec-
tion unless signs have been placed at the State line on the primary high-
way system, and outside cities and towns having over 3500 population,
on the primary highways to indicate the legal rate of speed and that the
speed of motor vehicles may be measured by radiomicro waves or other
electrical devices.

(d) Nothing herein shall affect the powers of cities or towns to adopt
and use such devices to measure speed.
