There are 2 cops parked along a one-way street looking for traffic violations. They spot a taxi driver going in the wrong direction, yet they do nothing.

Why?

A bus driver was heading down a street in Mexico. He went right past a stop sign without stopping, he turned left where there was a "no left turn" sign, and he went the wrong way on a one-way street. Then he went on the left side of the road past a cop car. Still - he didn't break any traffic laws. Why not?

Can anyone tell me a word in the English dictionary which has a silent 'z'?

When I got four, I have it none.
When I got two, I have it some.
When I got none, I have it all.

What is it?

I know a ten-letter word in the English language which can be typed using only the top rows of the computer keyboard.

It is deaf, Dumb and Blind!!!

Still, always tells the truth. What is it?
