I was on a 4 lane divided highway, speed limit 60 kph, and I passed a cop. I was doing 65. He pulled me over, and gave me a warning, telling me I wasn't allowed to pass a cop. His lights weren't on, and he was doing exactly 60, so I passed him, like I would any other car.

Is he being a jerk, or is it foolish to pass a cop who is doing the limit?

I searched the OHTA for any mention of not being allowed to pass emergency vehicles, but couldn't find anything.
