How do they work? Is there a camera also? Sometimes I see officers stand outside the vehicles with the radars pointing... Is it possible for a stationary highway patrol vehicle (with the copper inside) still able to get you? I think I may have been caught? Officer was sitting inside the highway patrol vehicle, whilst I went by Although there was a time when one of my mates, got caught speeding, from highway patrol who was travelling in the complete opposite direction, he did a quick uturn and went straight for my mate, and told him how fast he was going. BOOM. hmm?
