SpongeBob's driver's license is a drivers license given to SpongeBob in various episodes.
It looks like any average driver's license. It is printed on rectangular cardboard, with black ink writing. It has all of the information needed about SpongeBob, including his birth date and address. It lastly has his full name written at the top, with a bigger font.
He is never given his license permanently, due to a series of events resulting in its destruction in many episodes. For example, in "SpongeBob LongPants," SpongeBob is able to obtain a licence due to his long pants but its issuing was rescinded once he switched to shorter pants.
He is also seen to be a terrible driver, who annoys his boating school teacher constantly, Mrs. Puff, which he is clueless to the fact that she despises (most of the time) him. In the episode "No Free Rides," Mrs. Puff only gives SpongeBob his license in order to never teach him again.
On it, it states that SpongeBob's hair is yellow, but so far he has only been seen with hair in "The Sponge Who Could Fly."
