They do. Or at least some have something similar. In my younger days one shouted at us for chucking sweets at each other.
I got shouted at by a state trooper last year for having my headlights on full beam. Police in the UK should have megaphones on their cars too.
It's a deliciously playful pun on having vigourous sex.
I don't get it. Surely there's plenty of female state troopers around, especially these days. Shouldn't be too hard to see one.
If you see one you've been trucking too hard. Sheesh.

If you've seen even one 'state trooper' here you are really trucking too hard.
