A truck driver was driving along on a country road. A sign came up that read " Low Bridge Ahead."
Before he realised it, the bridge was directly ahead and he got stuck under it.
Cars were backed up for miles. Finally, a police car arrived.


The policeman got out of his car and walked to the truck's cab and said to the driver, "Got stuck, eh?"
The truck driver said, "No, I was delivering this bridge and ran out of diesel!"
