As with previous years, eight people, nominated by their family or friends, enter the Driver Rehabilitation Centre to improve their driving skills.
To Joe's shock, his daughter, Kristen, is then brought into the studio and she's able to persuade him to promise to be a safe driver, for his own sake as well as his family's.
With it obvious that there's nothing the experts can really teach Joe in terms of technical skills, the discussion quickly turns into one of how he should leave rehab; Tim does not believe his promise to slow down and advocates expelling him rather than letting him graduate.
When meeting with the experts, Ashley admits that the experience of the previous challenge made her physically ill. Julie is the only person who expresses any wish to graduate and vows never to be distracted at the wheel again.
While the experts consider Shayne to be the episode's best performer overall, for being the only driver who passed all three challenges, he tells them that he doesn't want to graduate just yet, feeling that he has more to learn.
The experts shortlist Adam (for finishing the Teeter-Totter in the fastest time), Breanna (for performing relatively well on both Parallel Parking and the Swerve and Avoid) and Shayne (for passing all three challenges and the clear improvement in his outlook).
The drive in question subsequently goes with no issues and, on her return, Breanna is given back her license and becomes the third graduate, ensuring that, for the ninth year in a row, there will not be an all-female finale.
Mélanie, however, admits that she might be Canada's Worst Driver and that, due to being a single mother, she can't realistically afford more driving tuition.
However, Philippe then dissents and deems Ashley the worst for her dismal Mega-Challenge performance and nearly causing a serious accident in the road test and Cam sides with him, pointing out that, as poor and negative as Mélanie's attitude in the final drive was, her mistakes were comparatively minor.
To Andrew's shock, Shyamala then changes her own mind and agrees with Cam and Philippe in that Ashley is Canada's Worst Driver.
