What is a prostitute's favorite form of traffic control?

Speed humps.

A cop stopped a guy for speeding.

He said, "Do you know how fast you were going?"

"I was trying to keep up with traffic," the guy replied.

The cop said, "But there is no traffic."

And the guy answered, "That's how far behind I am."

What did one traffic light say to the other?

"Stop looking, I am changing."

Say what you want about pedophiles, but at least they drive slow through school zones.

I can measure the speed of an object, because I want to km/s.
