Is this funny?

"When you drive on the road, you saw a sign. So, you turned down the radio. Why?"

This is supposed to be American joke.
Last night, a friend told me it but I didn't understand what point is fuuny.
He said why?, so I tried to look for the answer.
Then I said, "The sign says turn down the radio, so you did".
But another friend explained the sentence itself is funny.

Hmm...
I don't get it. :(
I don't know why American can laugh it...
