Camaro Challenge: The Swerve and Avoid – This annual challenge is dedicated to a fan of the show, who had taken the lessons from this challenge to heart and had narrowly avoided a truck using the skills taught from this challenge; she and her husband were invited to the Driver Rehabilitation Centre as guests for this challenge. Contestants will have two attempts at passing at 70 km/h. Lance hits the brakes and fails on the first go, and in his induced anxiety he fails his second run. Jamie, despite her nervousness, passes on her first try. Dale misinterprets her senses and hits the car on the first try, and hits the brakes on the second try. Despite Donna's yelling, Brad also passes, a stark contrast from the earlier cornering challenge. Diane fails going too slow and braking far beforehand, and is convinced to drive up to 100 km/h on a practice run before attempting her second run. On that run, she accelerates to 80 km/h, and almost clears it; she nevertheless is considered to have passed the challenge for overcoming her speed fears. Dean clears the obstacle at 80 km/h, but later spins out of control, and so fails that run. He skids too far and loses control in the second run, as well.
The Lane Change Rally – Each of the six contestants will compete in the head-to-head lane change challenge from last season. Contestants must drive at 35 km/h and pass Andrew twice in his car. Each incorrect lane change will be penalized by one additional required pass. Lance starts the challenge by racing ahead, and then stopping entirely when he realizes Andrew hasn't gotten into his car. This agitates Donna, and after Andrew temporarily halts the challenge in order to confront Dale, who had cut off Andrew three times, Donna lashes out at Lance for straddling two lanes and boxing Brad in. Diane and Raeanne also get involved in the scuffle as well, and Andrew is also forced to intervene. When the rally resumes, Dean becomes the first person to "finish"; unfortunately, he made three bad lane changes, and Brian failed to make Dean do the extra laps, meaning that he fails. Brad then finishes the rally successfully, but the experts refuse to consider it a true pass, since Donna was controlling Brad's every decision, and he still made four bad lane changes. Lance eventually gives up after getting nearly every lane change wrong, and has to park some distance away from the rest of the group, as Donna is more than ready to pick another fight with him. Jamie, despite making more bad lane changes than anyone except Lance and Dale, eventually manages to get the hang of it, and passes. Diane has easily the best performance on the challenge, as despite her slow and steady pace, she only makes two bad lane changes and finishes the rally with minimal input from Raeanne. Dale is therefore left as the last person on the course, meaning that she automatically fails; adding insult to injury, she still doesn't have any idea how to correctly change lanes.
Drifting Donuts – The challenge first introduced in Canada's Worst Driver 2 returns this episode. Though the challenge requires contestants to do only one donut in 30 minutes, Andrew does two to make up for his miss last year. Jamie steers ahead too often, and fails the challenge. Lance (who mistakenly believes a full circle is 365 degrees), also fails. Brad, with Donna cheering him on, passes with ease, and celebrates with donuts of the edible variety. Dean quickly grows frustrated, and fails. Diane manages to pull out the donut after several attempts. Dale, who had trouble learning the technique (having driven off the lesson course on a large number of occasions), hits the central obstacle repeatedly, and after nearly running Andrew over as a joke, is forced out of the car.
In deliberation, Brad states his case, having snapped after Lance's antics in the Lane Change Rally due to evoking memories of his mother's death; Brad's mother had been killed in a construction accident 20 years ago when she was run over by a dump truck. Lance knows he isn't graduating as a response, but promises to keep his attitude in check. Diane also states her case for graduation. Jamie also wants to graduate based on her performance.
In the end, Brad and Diane make the experts' shortlist due to their similar successes. The initial vote is 3-2 in Diane's favour, but Andrew questions this, as he still feels that Diane needs a little more confidence, whereas Brad's problem is more Donna's controlling behaviour. In the end however, Lauren actually talks Andrew and Cam into also backing Diane, who she points out was indisputably responsible for her own success in the Lane Change rally, whereas Brad performed worse even with Donna's constant advice. Diane therefore gets the unanimous vote to become the season's second graduate.
