§ 397-a. Radar detectors and laser detectors prohibited. 1. No radar
detector or laser detector shall be used in any motor vehicle with a
gross vehicle weight rating of more than eighteen thousand pounds or in
any commercial vehicle with a gross vehicle weight rating of more than
ten thousand pounds. The presence in such vehicle of a radar detector
or laser detector connected to a power source and in an operable
condition is presumptive evidence of its use by any person operating
such vehicle. Such presumption shall be rebutted by any credible and
reliable evidence which tends to show that such radar detector or laser
detector was not in use.

2. The provisions of this section shall not be construed as
authorizing the seizure or forfeiture of a radar detector or laser
detector, unless otherwise provided by law.

3. A violation of the provisions of this section shall constitute a
traffic infraction punishable by a fine of not less than twenty-five nor
more than one hundred dollars.
