Riddle:

A bus driver is heading down the street. He goes right past a stop sign without stopping, turns left where there’s a "no left turn" sign, and goes the wrong way on a one-way street. Then he goes on the left side of the road past a police car. Nonetheless, he didn't break any traffic laws.
Why not?

Answer:

He was walking, not driving, and didn’t have to obey traffic laws
