At the start of the episode, Andrew reiterates that the driver rehabilitation program has had a number of success stories – Manuel Tejeda (from Canada's Worst Driver) has not hit a thing since leaving rehab (amounting to over two years and 15,000 km of driving), while Jodi Slobodesky (from Canada's Worst Driver 2) is now in a job where driving well is paramount. Coincidentally, both had graduated in the second to last episode in their respective series. They were the only two drivers to graduate in the second last episode of the previous two seasons, excluding Sean McConnell (as the second last episode of Canada's Worst Driver 2 was the only episode of Canada's Worst Driver in which two drivers graduated).
Trailer Ride: In Ontario, drivers may carry a trailer with a maximum height of 13 feet 6 inches. In this challenge, after each contestant was given lessons in trailer driving, the contestants must drive such a trailer (in the form of a giant pylon) through a hairpin turn, up a hill, and then parallel park the vehicle (or reverse down the hill) when an oncoming emergency vehicle approaches. When the emergency vehicle passes, the contestants must continue up the hill and park in reverse in a parking space. Shelby is the best of the bunch, even though it still took him 15 minutes to parallel park, largely because he tells Elerick to get out of the car when he needs help. The rest of the contestants take over 30 minutes each to parallel park, and Jason destroys his own trailer as he makes his final park.
Stopping: Andrew notes that Adrian is one of the most controlling husbands who have appeared on the show (compared to Karen and Jodi from Canada's Worst Driver 2). To show how much of an influence this can get on Jason (who wants to graduate in this episode in order to return home in time for Adrian's sister's wedding), Scott monitors the pair as they try to brake from 40 km/h, with and without Adrian at the passenger seat. The conclusion: Jason is better off without Adrian at the wheel.
The Maze: In what's only the season's second navigation challenge, the contestants must navigate their car out of a maze. The contestants are given a map of the maze before the start of the challenge, and they are free to make copies of the maze on paper before they begin. Ed is the fastest out of the maze, and with the fewest hits – mainly as Elizabeth had copied the maze diagram and navigated their way out – though at the end, Ed was heading out of the maze in reverse. Jason and Jennifer hit many things on their runs for different reasons (Adrian's involvement and Jennifer's ignorance of hits). Shelby mistrusts his meticulously drawn map, and he gets stuck in the maze in the tightest of spaces – so much that when he finally makes it out, the car engine starts to overheat.
The Slalom: After Phillippe gives instructions to everyone on how to do a slalom while maintaining 40 km/h (and their hands on the nine-and-three and why the traditional ten-and-two may cause injuries when combined with modern airbag technology), the contestants attempt to do the same thing – except that at the end of the course there will be a flagbearer, and if the flag is raised, the contestants are directed to not swerve around the obstacles until the flags are lowered. If they lose control of their car (either in swerving, hitting an obstacle, or failing to maintain 40 km/h), or if they fail to obey the flag, they must reattempt the course again, up to a maximum of seven tries. Ed's peripheral vision issues prevent him from finishing this challenge, while Jason and Shelby fail in their seven attempts (Jason from failing to maintain speed, Shelby from impacts with the obstacles). Jennifer, believing that all hope was lost, manages to finish on her last attempt.
At the end, Jason and Shelby are quickly ruled out as graduates – Jason, because often he didn't know which way his wheels were positioned, and Shelby because of the belief that he, in fact, got worse. The judges are split again on who goes again (Dr. Gembora and Scott choosing Ed and Cam and Andrew choosing Jennifer) – with Phillippe holding the swing vote. Phillippe is quick to decide that Ed, whose relationship with Elizabeth has gradually improved over the course of the challenges, should be the next graduate. Ed also admits that he was not as good of a driver as he had thought, and that alone has helped the couple reconcile.
