Airbag Safety: Before the first challenge, Andrew gives the remaining five drivers a brief safety lesson on the dangers that can be caused by the violent inflation of an airbag, as nearly all of them have bad habits that could cause them to be injured (Mariah's constant smartphone use, Tyler's habit of hunching over his wheel, Jason's incorrect wheel grip, and Chanie's bizarre driving posture; Siham is again the only driver with no major issues in this department). The triggering of a Honda Civic's passenger-side airbag is shown to be so violent that it blows the rear-view mirror into the car's backseat, shocking the five drivers.
School Bus Three-Point Turn: While challenges involving a three-point turn are commonplace for the show, the task is much harder this year, as the drivers each have to drive a school bus (which Andrew adds is being used to give the drivers a lesson in front-end swing) into a large turning space bordered by cars, and make a three-point turn without hitting anything. Each driver has 40 minutes in which to complete the challenge. Chanie, who didn't even know what a three-point turn was until a few days ago, initially doesn't use her mirrors and makes no effort to avoid hitting the cars. Andrew draws her a map to illustrate how to do the challenge, and she completes it on her next turn. Tyler also didn't know what a three-point turn was, but he manages to carry it out on his first turn without Andrew even needing to explain it, finally passing a challenge. Jason fails all of his first three runs within seconds, as the front-end swing causes him to hit the barriers leading into the turning space. He fails after running out of time, though is able to work out how to do it after the fact. Siham technically succeeds on her first go, but it isn't considered a true pass since Wayne directed her throughout. Mariah ends up using the entire 40 minutes on her first attempt alone, as her overly-tight turning causes her to get stuck, and her inability to get out causes her to fail. However, Andrew teaches her how to do the three-point turn after the challenge has officially ended.
Forward Handbrake J-Turn: In what is noted to be one of the show's harder challenges, the drivers must each drive a Ford Mustang coupe into a small turning space at 50 km/h, and use the handbrake to spin the car around 180 degrees while dodging an oversized foam birthday cake, before safely driving out of the space. Each driver has three chances to succeed. In his first turn, Jason somehow forgets that he's supposed to use the handbrake, and hits the far wall with the car still entirely facing forwards. He makes a similar mistake (using the footbrake) on his second turn, and his inability to even comprehend the difference between how a footbrake and a handbrake works causes the experts to again question Jason's suitability to drive at all. He finally gets the technique somewhat correct on his third attempt, but carries it out too late and hits a side wall, failing. Tyler relies on Q to read out his speed during his first two attempts, and he fails his first attempt when he uses the footbrake. His second attempt goes better, but only spins the car by about 140 degrees. His final attempt is taken too fast, at 60 km/h, but he still carries out the technique correctly; Andrew tells him that his speeding would normally cause this to be deemed a failure, but agrees to call it a pass since he did it without Q's help. Chanie appears to pass the challenge on her first attempt, but the experts and Andrew refuse to consider it a pass, as she pulled the handbrake early and missed the cake by just inches. She's forced to take her second run, and becomes unresponsive, forcing Jeremy to pull the handbrake for her. Jeremy is asked to sit out Chanie's third run, and she finally passes the challenge. Wayne asks to sit out Siham's run, afraid that the challenge would trigger his motion sickness, and Andrew is all too happy to take his place in the car, which will force Siham to think for herself. Unfortunately this does not lead to Andrew's hoped-for result, and she posts the worst performance of the day, smashing through the outer walls on all three attempts, causing Andrew to realize that her self-confidence is even lower than he (and Shaymala) previously thought it was. Mariah's run is less dramatic, but she fails all three attempts due to her using the footbrake instead of the handbrake.
Cadillac Challenge: The Reverse Flick: In an attempt to take advantage of the previous lesson still being fresh in the heads of the drivers, the show's other car-spinning challenge is the next one to be held. This time the drivers have to reverse into a turning space at 40 km/h, and again spin the car around 180 degrees, with the number of chances also being three. Due to Andrew only narrowly passing his demonstration, the course is widened to make life easier for the others. Jason again gets the first run, and fails all three attempts; on his first go he leaves it far too late to steer, and on his second and third attempts he doesn't even get into the turning space, crashing through the barriers that make up the entry lane. Mariah also smashes the entry barriers on her first attempt due to not looking where she wants to go, but passes on her second attempt after she focuses properly. On his first attempt, Tyler hits the entry barriers; he fails his second attempt due to driving too fast (at 60 km/h) and turning too late, and his third attempts ends in failure for largely the same reason, along with Q still telling him what to do. A clearly unenthusiastic Siham becomes the third driver in a row to hit the barriers in her first run, and take it a step further by not even bothering to stop and smashing one of the turning area's walls. Before she takes another run, Siham gets a private lesson from Andrew, in which her erratic driving ends up triggering Wayne's motion sickness. She then takes her second run with Andrew as her passenger, and passes. Chanie has the final run, and after drastically failing her first run by smashing the entry barriers at high speed, she admits to having no reversing experience whatsoever before being on the show. On her second run however, she passes with ease.
While Chanie is noted to be the obvious front-runner to graduate, as she passed every challenge, she admits not fully comprehending all the challenges, and that she should stay in rehab for the time being. Siham and Tyler, who both passed two challenges, also say they don't want to graduate. Mariah and Jason, who passed one challenge and no challenges respectively, aren't even considered for graduation.
Cam and Philippe nominate Chanie to graduate, as she was statistically the best driver this episode, though Cam isn't overly enthusiastic about letting her go. Shyamala and Tim, on the other hand, feel that Siham is the person who deserves to graduate, as they consider her the most technically adept of the five remaining drivers, despite her confidence issues. Andrew is left to break the tie, but elects not to back Chanie or Siham, as he feels they are both still lacking in focus and confidence respectively. In what Andrew notes has become something of an annual tradition for the show, the season's fifth episode ends with no-one graduating.
Web Extra: Road Signs: As is often done on the show, each of the drivers was given a brief test by Tim on their road sign awareness. Siham and Tyler post the joint-highest scores, while Chanie posts the worst score, getting just 3 out of 10; and although she correctly identifies a "yield" sign, Chanie admits to having no idea what she's actually supposed to do when she sees one when she's driving.
