Head-to-Head Reversing: The first real challenge of the season has the drivers paired off and required to reverse down a lane marked with wheel rims and wooden barriers, turn the car around in a large turning area, and then reverse back down their lane; in a new twist on the challenge however, their starting lanes are directly opposite each other, rather than being in parallel. Before the challenge, Tim will give each pair a lesson in reversing. Jordan and Renee make up the first pair, and after hitting a set of wheel rims early on, Jordan panics and floors the glass, taking out much of the course in the process. Renee fares a little better, but still has a lot of minor hits; Andrew also calls her out on sitting far too close to the steering wheel, which would cause the airbag to severely injure or possibly even kill her if it deployed. Jillian and Polly both take some time to get going, after initially not being able to put their cars in reverse. Jillian initially has a lot of trouble due to her nervousness, and so Andrew ejects Mitchell from the car and has her drive back and forth up the starting lane; while she has a few minor bumps during the process, she's nonetheless deemed to have passed, thanks to getting over her nerves. Polly never once looks out the back window, and while she doesn't actually do too much damage to the course, she fails for not following the lesson. Alex and Cameron are next, and both their runs end in failure, with Alex driving recklessly and hitting things throughout, and Cameron doing a little better, but causing several hits while turning the car around in the middle. Tina faces Shmuel and Sholom in the last round. Tina is easily the best performer in the challenge, passing without making a single mistake, but Sholom has major trouble even getting the car to move, and hits multiple things in the middle section; Shmuel does better than his brother after they swap at the halfway point, but ruins what would otherwise have been a pass by hitting the barriers near the finish line.
Riding the Rails: In a new variation on the "Running the Rails" challenge seen in previous seasons, the drivers have to drive a Jeep over two sets of rails, with the first going under the car's right wheels, and the second (which starts a few feet before the first finishes) under the car's left wheels. The drivers will each have five attempts, unless they get stuck and unable to drive off, which will cause them to instantly fail. Cameron uses up his first two attempts just getting onto the rails, and on his third attempt he falls off and gets stuck, causing him to fail. Tina nearly passes on her first attempt, but gets overconfident and goes too fast, which causes her to fall off and get stuck. Alex fails in the exact same way as Tina, though unlike her, admits that he got too cocky. Jillian passes without any real difficulty, reinforcing Mitchell's belief that she is a capable driver, and that her real problem is her nervousness on the road. Jordan doesn't make a real effort in the challenge; he needs two attempts just to get on the rails, and then gets stuck on his third attempt, all the while laughing at his failures. Renee initially does well, but then speeds and drifts to the right, causing her to fall off and get stuck. Sholom proves the worst so far, and uses up all five attempts without ever getting more than a few feet up the ramp. As with the previous challenge, Shmuel does better than his brother, but still fares poorly, falling off on the first two attempts and then getting completely stuck on the third. Polly does the first half of the challenge well, but needlessly starts jerking the steering wheel around halfway, causing her to fall off and get stuck.
Charger Challenge: The Shoulder-Check Challenge: After a lesson in shoulder-checking from Philippe, the drivers have to drive the Charger down a lane at 75 km/h, check over their shoulder for a sign indicating which lane they should turn into, and then navigate around a stack of boxes into the correct lane. In a twist however, both lanes will be marked as open, to make sure the drivers actually check over both shoulders. Polly doesn't even make it all the way down the lane, as she pulls the wheel to the right when she shoulder-checks in that direction, and ends up crashing into the barriers. Renee is so nervous about the speeds involved that she initially doesn't want to do the challenge, and so Andrew gives her a personal demonstration of how to do it, before getting to drive at 100 km/h down the other end of the track. When Renee actually does the challenge however, she fails by calling out the left lane as red instead of green, and then turns too early and smashes the last lane barrier. Alex bizarrely calls out the left sign as "yellow" rather than green, but otherwise carries out the challenge correctly, and Andrew agrees to let his mistake slide and call it a pass. For Tina's run, the left-hand sign is changed to being red; she nonetheless passes flawlessly. Despite her continuing nervousness, Jillian also passes without any major problems. Shmuel correctly carries out the shoulder-checks, but steers too late and clips the boxes in the middle, causing him to fail; Andrew also bring attention to his wearing sandals while driving, which he warns Shmuel is not an ideal choice of footwear. Sholom takes the course far too fast (at 100 km/h), only checks over one shoulder, and then spins wildly out of control at the end. Cameron makes much the same set of mistakes as Sholom, and also panics and pumps the brakes, causing him to spin out of control and destroy a large chunk of the course, which also smashes the Charger's front headlights. Shockingly, Jordan becomes the third driver in a row to make this set of mistakes, and ends up losing control even more wildly than Cameron or Sholom, thanks to him both pumping the brakes and hitting the gas at the same time.
While Jillian seems the obvious front-runner to graduate, as she passed every single challenge this episode, she tells the panel that she'd prefer to stay in rehab in order to get more confidence, as she still feels unable to face driving in public. Tina and Alex both express the desire to graduate, and the panel note that both are clearly capable of driving well (Tina doing so around motorcyclists due to being an occasional biker herself, and Alex being more considering when driving his grandmother), but have doubts over their attitudes. The remaining drivers all admit that they should stay in rehab.
Tim votes that Tina should graduate based on her overall better performance in the episode, while Philippe prefers graduating Alex, pointing to Tina's angry, defensive reaction when the panel initially confronted her on her attitude toward driving. Shyamala sides with Tim, and Cam with Philippe, leaving Andrew with the deciding vote. In the end, Andrew makes a shock decision and decides that both are equally worthy of graduating, making this the first episode to have a double-graduation since all the way back in Canada's Worst Driver 2. Before they leave, however, Andrew gives Alex a cardboard cut-out of his grandmother, to ensure that he always drives as if she's with him, and also confiscates the "If you don't like my driving, f*** off" sign from Tina's car.
