At the beginning of the episode, Andrew reveals that a fan by the name of Will Vanda sent him a letter thanking the show for teaching him the Swerve and Avoid technique, as it saved him from a fatal accident. In response, Andrew invited Will to the rehab centre so he himself, the panel and the production crew could all hear it in person.
Know Your Limits Slalom Challenge: In a test of how well the nominees know their own limits, they will be driving through a slalom course that is 40 m (130 ft) long between at 70 km/h in the show's vintage Cadillac. Brandon is up first and while he passes the initial distance, his request to shrink the distance to 20 m (66 ft) each ends up in failure as he loses control after the second swerve and crashes into the side barriers. Descyara also passes the initial distance and, despite Drew's concern about her request to reduce the distance 25 m (82 ft) (as her overconfidence has caused accidents in the past), she manages to pass the challenge. Alexis asks to reduce it to 30 m (98 ft) and while she passes, she requests that she be in the finals in order to prove she has improved a lot since entering rehab. Brittany is the final person up, but fails the initial distance due to target fixation on the final foam figure; she also fails her request to do the course at 30 m (98 ft) by hitting two foam people. After this, Brittany makes the promise that if she is named the worst this season, she will give up driving permanently.
The Cross Challenge: As Andrew believes the nominees should know how to drive a vehicle in tight situations without hitting anything by this stage of the season, the Cross Challenge will test how they back up a Jeep Grand Cherokee into four spots while also performing S-turns. Additionally, they have access to a birds-eye view camera to help them during the challenge. Descyara is up first, but her impatience causes her to hit the Jeep seven times in 12:15. Brandon fails to set his mirrors properly before starting and hits multiple barriers until he does so. However, Brandon does not set his mirrors correctly and he damages Jeep repeatedly, finishing with 19 hits in 15:55. Once again, Alexis is careless throughout the challenge, and gets annoyed when Andrew. Brittany is the final person up where she continually hits the barriers, finishing with 14 hits in 12:35.
Mustang Challenge: Icy Corner: In what has been known to be the most important skill for the drivers to learn, the nominees have to drive 50 km/h around a simulated icy corner by turning left after braking on the skid and making it through the opening. To drive home the point further, the show has disabled the Mustang's ABS feature (although Cam states that even with ABS, this challenge is needed to show how much control is required to execute the manoeuvre). Brittany is up first, but speeds on her first two attempts up to 60 km/h before hitting the wall due to target fixation and her third attempt sees her hitting the wall due to oversteering (causing the wheels to take longer to grip the surface) on her three remaining attempts before understeering on her fifth and final run, despite getting a reminder lesson. Afterwards, Andrew shows her how the ABS works and Brittany asks to be in the final three, as she wants to show her family that she can drive safely. For Descyara, this challenge is paramount as she nearly died from a icy corner-related accident. While she fails her first attempt due to speeding to 60 km/h like Brittany before her, she manages to pass the challenge on her second. Like Brittany and Descyara before her, Alexis fails her first attempt due to target fixation, but while she performs the manoeuvre perfectly on her second attempt, she does so at 48 km/h and is forced to make another attempt at speed, which ends with her hitting the wall again before deciding to quit her remaining attempts. Brandon fails all five attempts due to fixating on the wall, causing him to request to be in the finals and make the same promise as Brittany-- to quit driving if he is named Canada's Worst Driver.
When meeting with the experts, both Brandon and Brittany reaffirm their promise to quit driving if named Canada's Worst Driver. While Brittany plans to start taking the bus if she wins the title, Brandon plans to start from scratch, Alexis still remains defiant on the front of giving up driving if she were to win the title. Descyara wants to graduate, even showing the panel that she recently had the word "focus" tattooed on her left hand. Despite the fact that Alexis, Brandon and Brittany have already filled up the three spots for the final episode, Andrew reveals to Descyara that half the panel wanted to keep her around for the final episode, while the other half felt that she should graduate. Ultimately, Andrew, who was left with the deciding vote, opts to let Descyara graduate, as she has not only shown herself to be the most improved, but he strongly believes her promise to commit to safe driving.
