How does police radar work?

[Wayne Maybury]

To answer a couple of the remarks / questions.

Yes I was speeding but not nearly at the speed he said. The police car was just inside a construction zone where the speed was decreased from 100 kmh (65 mph) to 70 kmh (45mph). When I entered the zone I was decreasing my speed from about 110 to eventually 75. I believe that I was doing 90 to 95 kmh when I first entered the zone. He ticketed me for 114 kmh which is higher than the speed I was travelling in the 100 zone.

I was following 3 or 4 smaller cars with my Explorer but I was being passed by a duel wheel crew cab Dodge pickup which is definitely bigger than my Explorer. I'm not even sure the pickup was doing 114. The pickup did pass me then cut in front of me once he saw the police car. He knew that he had been caught as he kept looking in his mirrors waiting for the cop to pull him over.

First to pull over once the flashers are on is a good one. Well that is interesting. As I said there were 3 or 4 cars ahead of me, then the pickup pulled in directly in front of me and the police car began following directly behind me. We continued on that way for about a mile at which time I had to take an exit but all of the other vehicles kept going straight. The police car follwed me and only turned on his flashers once I had taken the exit. I had no choice but to stop and everyone else was long gone by then.
