Running the Rails: This challenge, previously run in Canada's Worst Driver 6, places the drivers at the wheel of a RAV4 and requires them to approach a short track made up of two rails, drive onto it and follow the rails to the end, and then reverse off it. The drivers have only one chance, and falling off and being unable to continue will result in an immediate fail. Michael is the first to take the challenge, though Yolanda is unable to accompany him, as she has a congenital hip defect which has been exacerbated by her being involved in car crashes. Michael completes the forward part without much difficulty, but then gets dangerously close to the end of the track, and drives completely off it after accidentally putting the RAV4 in first gear instead of reverse, though Andrew still notes that he seems reasonably aware of where his wheels are. Dale doesn't even manage to get fully on the track before falling off, and fails. Kevin, despite Lenny's coaching, only gets halfway up the track, and falls off after accidentally steering into the side of the track he was about to fall off of. Angelina refuses Christine's advice to adjust her mirrors, and proves so unaware of where her wheels are that she takes six attempts to get onto the rails, and then falls off immediately. Unlike Dale however, she is able to back out and retry, though on her next attempt falls off halfway and fails. Shirley executes the challenge flawlessly, despite Janis's constant panicking (which causes Shirley to call her "worse than Angelina," a statement which greatly offends Janis). Shelby does well on the forward section, but his failure to adjust his mirrors (Elerick deliberately neglecting to tell him to do so) causes him to fall off halfway through reversing. Sly constantly attempts to solicit Fred's advice in the challenge, but Fred refuses to give him any. Sly eventually gets to the end, but is mere inches from falling off. Sensing the inevitable, Fred gets out of the car, and seconds later Sly falls off, failing.
Road Signs: Tim tests the seven drivers on their road sign knowledge, a test which it's noted all the drivers have previously been through. Shirley got 8 out of 10, which was both the highest score overall, and the biggest improvement over the original appearance of any driver. The four men, Sly, Shelby, Kevin and Michael all get at least half of the signs right, though their exact scores are not revealed. Dale and Angelina post the joint-lowest scores, with 2 out of 10.
Crazy Eights: This test, which was also last run in Canada's Worst Driver 6, pits two drivers at a time against each other in a pair of Suzuki Sidekicks driving in a figure-eight course of wheel rims, with a combination of S-turns and accurate reversing required to get through the course. Shelby and Shirley make up the first heat, and though Shirley needs Andrew to refresh her memory on how to perform an S-turn, both get through the course flawlessly. Dale and Michael are next-up, and while Michael also makes it through without any trouble at all, Dale hits 19 objects, and fails. The Suzuki Sidekicks are then swapped out for two Pontiac Fieros. Kevin and Angelina make up the next heat, and Kevin continues to demonstrate his problem of only ever looking forward and rarely turning his head, which causes him to run over several wheel rims, and fail. Yet again, Angelina has the worst run, and backs completely off the course and into a field. She attempts to give up after this, but Andrew forces her to continue, and Angelina's repeated complaining causes the viewing judges to conclude that she's emotionally immature. During the challenge, Angelina reveals that her cousin suffered brain injuries in a car crash, causing memory loss which rendered her unable to even remember who Angelina was, leaving Andrew further astonished by her cavalier attitude toward driving. Sly takes the last run alone due to the lack of another driver, and in a repeat of the initial test is extremely slow, taking 97 minutes to get through the course.
Camaro Challenge: The Shoulder Check Challenge: In one of the show's most frequent challenges, the drivers each have to approach a split lane at 70 km/h, and then check left and right over their shoulder to see which lane (designated by a green marker) they must turn into. Each driver has two runs. Angelina is first-up, and on her first run drives at 100 km/h and closes her eyes, crashing straight through the central barrier, splitting the Camaro's front bumper in half and damaging its radiator. After the Camaro is repaired, Angelina takes another attempt, and nearly gets it right, but understeers and clips the barrier. Kevin understeers on his first turn, also clipping the barrier, and on his second run he steers too early and hits the lane markers; as he and Andrew note however, even this result is an improvement on the previous year. Shelby gets the challenge exactly right on the first go, as does Shirley. On his first run, Sly can't even make it to the end of the straight before driving through the lane markers, due to him turning his whole body rather than just his head. He then hits the lane marker again on his second run, this time by steering too soon. On his first run, Michael drives too slowly (at just 60 km/h) and slows down further toward the end of the straight. Andrew asks Yolanda for her honest opinion, and she launches into a tirade against Michael, which Andrew and the experts feel is an overreaction, and theorize is caused by pent-in anger at the driving-related injuries she's suffered in the past. On his second go, Michael passes with ease. Dale seems to get the technique right on her first go, but inexplicably turns into the lane she's told not to turn into. On her second go, she only checks over one shoulder and clips the central barrier, causing her to fail.
Angelina has a lengthy discussion with the judges, and admits that she is no longer on anti-depressants due to her original psychiatrist having retired, and her being unable to find another in the Sudbury area. Shymala tells Angelina that while she can't prescribe drugs, she can help her deal with her issues, and Angelina agrees to as many therapy sessions as it'll take. Along with Angelina, Sly, Dale and Kevin all admit that there's no way they'll be graduating this episode, as they didn't pass a single challenge between them. This leaves Michael, Shelby and Shirley, who each had some degree of success in each challenge this episode, as the pool of potential graduates.
Despite all three wanting to graduate, the judges decide that there is no need whatsoever for a discussion; Shirley, who was regarded as the most capable driver of the group (apart from Chris) even before rehab, and the only driver who fully passed every challenge this episode, becomes the next graduate, with Andrew describing her as "inspirational" and saying that he only regrets that she can't be around for longer.
