I don’t recall ever getting a warning.
The last speeding ticket I got was on the NE end of Stoney Trail heading south. I was expecting some questions but instead he just said I was going 20 over, asked for licence and registration, and returned with my ticket. Not much conversation at all. I tried to be considerate and pulled way over to give the officer some extra room away from traffic but he just approached on the passenger side so no help there.
