A truck driver was driving along on the freeway.
He sees a sign that reads, "Low Bridge Ahead".
Before he knows it, however, the bridge is right ahead of him and he gets stuck under the bridge.
Cars get backed up for miles.
Finally, a police car arrived.
The officer got out of his car and walked to the truck driver, put his hands on his hips and said, "Got stuck, huh?"
The truck driver replied, "No, I was delivering this bridge and ran out of gas."
