The DMV Tester is a tall light purple fish with a light blue dorsal fin that wears a lime green coat with a purple bow tie. He is balding.
The DMV Tester is first seen where he was taking the road test with SpongeBob after he decided to try it out due to wearing long pants. After SpongeBob parked the vehicle after slamming into two others, the DMV Tester was originally going to fail SpongeBob and even send him to jail but decides to give him his license thanks to his long pants (which indirectly upsets Mrs. Puff). However, at the end of the episode, the DMV Tester tears up SpongeBob's license after seeing that he is wearing shorter pants.
