The episode starts as one fish is doing the boating course perfectly with Mrs. Puff, and then it is SpongeBob's turn.
SpongeBob puts the boat to reverse then it crashes to the obstacles and then crashes into a house. Mrs. Puff gets very angry at SpongeBob after he fails the test again. At home, Mrs. Puff thinks about how SpongeBob could pass his driving test and then realizes SpongeBob is afraid of the course and if he took him to drive on a real road, he would pass. Mrs. Puff goes to SpongeBob's house and tells him to forget what she said earlier. Mrs. Puff takes SpongeBob to an abandoned road but SpongeBob was scared.
Mrs. Puff tells him to keep repeating "Focus on the road, there is nothing but the road" to get his confidence back. SpongeBob follows her instructions and imagines himself doing crazy driving tricks and poses as he proceeds to repeat the phrase. When SpongeBob has almost passed all the tests, Mrs. Puff tells him to safely dock the vessel as the last step, but due to constantly repeating the phrase, SpongeBob has mesmerized himself into a daze and cannot focus on what he is doing. He soon drives out of the road and freaks out. SpongeBob gets on a dangerous shortcut and gets back on a road, but he actually got on a 10 lane seaway and he is gripped with fear and cannot concentrate.
A police officer sees them speeding and thought they were reckless drivers because Mrs. Puff crossed the county line which she shouldn't have done. The police officer tells SpongeBob to pull over, but instead he accelerates. Then when Mrs. Puff tells to stop the vessel again, he finally parks the boat safely. Mrs. Puff gives SpongeBob his driver's license and screams: "I'm free!." But the police officer doesn't think so and arrests Mrs. Puff for violating the parole and rips up SpongeBob's license. As Mrs. Puff goes to jail she says "SpongeBob, I'll get you for this! I'll get you!" and the episode ends.

Running Gag: SpongeBob saying "Focus on the road. There is nothing but the road."
Nickelodeon featured SpongeBob's "Biggest Boating Blunders" which is a marathon with many boat-related episodes leading up to this episode, such as "Doing Time," "Boating Buddies," and "No Free Rides."
When Mrs. Puff sat down on her couch, a small picture of her sitting down at the same shot can be seen next to her, making an infinite picture. This is a callback to another infinite picture in Mrs. Puff's house in "No Free Rides."
Charles returned as a character in a show that two fish are watching.
During SpongeBob's episode of psychedelic scenes due to his hypnotic mantra, SpongeBob is shown to be driving on a mobius strip, a figure with only one side, and one boundary, though it can be easily made from one strip of paper.
When Mrs. Puff muted SpongeBob, he mouthed the word "unteachable."
When SpongeBob jumped the missing section of road, he put the boat in to "J" more than likely meaning "Jump," which isn't a real feature.
"Tutor Sauce" is the second episode in Season 9 to focus on SpongeBob failing his driving test. This is the first episode in this season to do so.
This episode premiered in Canada four years after "Pet or Pests" premiered.
In the German dub, this episode is called "Denk ur an die Straße," which means "Just Think of the Road."
This episode originally had a Meanwhile... time card before it was cut.
This episode's title comes from the term bumper to bumper, which means that traffic is moving close together very slowly.
When Mrs. Puff was thrown into the police car, she was wearing hand cuffs. When she appeared at the window threatening to get SpongeBob, her hand cuffs were suddenly gone.
When the policeman first yelled at SpongeBob, he had a megaphone. In the next shot after SpongeBob accidentally sped up, the policeman's megaphone had suddenly disappeared, though it was never shown when he put it away.
When the policeman came up to Mrs. Puff, the security cuff on her ankle disappears (also mentioned missing during the exam), then when she looks down at her ankle, it reappears.
Mrs. Puff's shoes are miscolored black from their usual red throughout the episode.
When Mrs. Puff tells SpongeBob to scoot over, he has a seatbelt on. Then it zooms in some and his seatbelt disappears.
