Radar gun usage
I thought possibly some LEO's or techies may be able to answer this question. (not quite sure what forum this belongs in)
When using radar to clock a vehicle, are you allowed to adjust the measured speed of the vehicle to account for the cosine effect or are you limited to clocking directly approaching/leaving traffic only?

You cannot manipulate the reading while you are measuring a vehicle's speed.
The only way you can get a reading, other than measuring a vehcile's speed, is to use a tuning fork.
Those only come in speeds like 35, 50, 70, etc.

Even though the Cosine Effect benefits the vehicle being clocked, the radars do not permit any speed munipulation.
