Radar Gun
Yes, as long as its an old car.
Of course they can all they have to do is hold the radar gun with one hand and the wheel with the other
A radar gun police use to check for speeders.
They use a radar gun if they want to measure one car at a time, and they use a two-way digital radar if they want to know the speeds of cars in front of where the cop is driving and the car going the other way on the other side of the street.

There's different kinds of technology that may, or may not, be used; it's dependent on the department. In general, the term 'radar gun' seems to be broad enough to fit all of these tools in. They point the radar gun at the vehicle, and the radar gun comes back with the speed of the vehicle. The police also have other methods, but they're not nearly as reliable, and, for the most part, are discouraged.
A radar gun measures speed of a moving object basically cops use them
Police use a radar gun to catch speeders because with a radar gun, you can see the speed limit somebody's doing and if it is way over the real speed limit, you just put on your lights and siren and chase after them. So, you use a radar gun. **********PEACE*********LOVE***************ROCK ON*************

Radio frequency electromagnetic radiation.
Yes, they use radars that bounce waves off your car and then the waves come back through the radar gun and tells how fast your traveling. There are also new laser radars that are better at singling out a single car from a large pack of them. So yes they dont need light to get a reading from a radar gun to tell them how fast you are going.
