SpongeBob is planning on getting his driver's license and going on a road trip with Patrick, but he fails the driving test yet again. He decides to use his bike to go on the trip, but Patrick weighs down the side car so they could not move. Then, Patrick remembers that he had a license, so he drove. They go to many places, but eventually, they end up with no money and gas. A man tows them back home with his bike and sings them songs.
SpongeBob is in a fishbowl and there's a fish, two seaweed, and a sandcastle.
This is one of the few SpongeBob books to not put the title on the front cover.
This book was later released as "Deep Sea Driving."
