How can a cop tell how fast you’re going?

Police use sophisticated radar guns to check the speed of vehicles as they travel. The technology at the heart of the radar gun is, of course, radar, which stands for Radio Detection And Ranging.

What happens if you get caught with a speed gun?

If the police officer with the radar gun deems it safe enough to catch up to you and pull you over, then they will probably take this action and then issue a fixed penalty notice on the spot. But if the officer thinks they may endanger other motorists or the weather is unfavourable, then they’ll probably stay put.

How far should a police officer pace you while driving?
