Cop car technology? - Click HERE for Original Thread

I have a freind who got a ticket out near banff a while ago. He was going towards banff and the RCMP officer was heading out of banff. He turned his sirens on u turned and pulled him over. Do they have a laser built into the car to tell them the speed of traffic going in the other direction? If not how did he give him this ticket. It said laser on the ticket.

I've addressed this before, search is your friend.

Laser radar reports instantaneous velocity. Ok, it's not technically instantaneous, but consider it as the limit as the difference in time approaches 0 of your velocity. Whether you are going forwards, backwards, accelerating, slowing down, driving in the same direction, opposite direction, whether the cop is moving or stationary, etc, an officer can detect your speed.

So is it only for the car in the inside lane?

I was too lazy to search

No, it's not.

Perhaps next time I'll be too lazy to answer.

As an aside, in-vehicle radars usually aren't technically "laser", but they fall under "laser" when filling out a ticket.

I highly doubt that. Thanks for the info though.
