I've seen quite a few instances where a police crown vic pulled over (in action) a speeding vehicle ahead of me without setting off my RX65. I'm assuming he did not clock him with a radar gun at all.
Are the cops allowed to pull people over without accurately clocking their speed with a radar or lidar device?
On the way up the mountain to my university are usually young drivers going 30-40km/h above the limit. And I witnessed this poor guy getting pulled over on the first day of school... without even using radar...
I live in Vancouver, BC.
