Know Your Speed: For this year, this challenge has been extensively overhauled, with the challenge now requiring the drivers to drive a mobile home down a long stretch of course, with a target speed of 30 km/h in the first section, 50 km/h in the second, and 70 km/h in the third section. The speedometer will be blacked out, however, forcing the drivers to use their judgement in deciding on a speed.
Krystal is supposed to be first-up, but gets into an argument with Steven over her continued insistence on using her phone while at the wheel, and then when Andrew tells her that she's making a fuss over nothing, she storms off and refuses to attempt the challenge. Tyler's run proves much less dramatic, but he still drives well over the target speeds, going 15 km/h too fast in the first section and 20 km/h too fast in the second and third sections. Daniella goes 10 km/h too fast in the first section, despite her fears of driving at speed, but is on-target in the second section, and actually 10 km/h too slow in the third section. Mike is even more over-cautious, going around 10 km/h too slow in all three sections. Lou is the slowest of all, however, by 10 km/h in the first section, and 20 km/h in the second and third. Krystal, after making an implied threat to quit the show unless Andrew apologises for what she claims to be overly vindictive behaviour towards her, finally relents and undertakes the challenge; when she does so, she speeds far more even than Tyler did, going double the speed limit in the first section, 40 km/h too fast in the second, and 30 km/h too fast in the third.
Trailer Parking Challenge: After Tim gives each driver a lesson in how to properly reverse a trailer - with Andrew noting that a lesson was not originally scheduled, as the experts felt this was something the drivers should be able to do without needing a lesson, but one was added to the schedule anyway after Tyler requested one - they have to use a van to reverse a trailer down a straight track, and then back it into a garage that's on a right-angle to the track. Tyler is the first to attempt the challenge which, in a change of form, he passes flawlessly at the first time of asking. During his run, Jana reveals that Tyler actually has a brain injury himself, after he was involved in a crash that sent a metal pole into his skull. Despite a frustrating experience during Tim's lesson, Daniella also succeeds on her first attempt, after looking up online tutorials on how to reverse a trailer. Mike also passes without difficulty, despite initial worries. Lou doesn't fare nearly so well, however, and a combination of her forgetting the lesson and Derek's poor advice sees her take well over a half-hour to pass the challenge, a performance not considered worthy of a pass. Krystal is the only driver who fails to finish, as she tries to take a shortcut by driving onto the field in front of the garage so that she can reverse the trailer straight into it, which causes the van to get stuck in the mud.
Mustang Challenge: The Icy Corner: In what is considered one of the most critical challenges taught on the show, the drivers are given a lesson in how to correctly navigate around an icy corner, and then have to get the Mustang through a simulated icy corner. Each driver will have five attempts. Tyler is up first, and surprises Andrew by revealing that he disabled the anti-lock braking system on his car at home (despite the increased chance of an accident) because he didn't like the jerky feeling on the brakes, causing Tim to point out this proves Tyler has a habit of braking too harshly. Tyler subsequently fails his first two runs by forgetting to release the brake, his third and fourth by over-steering, and his final run by speeding. Daniella badly over-steers on all five runs, and also releases the brake too late on most of her attempts, causing her to fail. Lou's first five attempts aren't shown, but they all end in failure (implied to be the result of taking the corner too tight), causing Andrew to allow her an extra run in which he walks her through each of the steps required, after which she succeeds. Mike, in stark contrast to the episode's first challenge, drives far too fast on his first run and is left with no time to carry out the manoeuvre. He fails his next three attempts by staring at the wall and under-steering, and his final attempt by pumping the brakes. Krystal fails her first two runs by speeding and pumping the brakes, and then the next two by steering erratically. Determined to see at least one person pass, Andrew gets in the car with Krystal, and while her final run is the best of the day, it still narrowly ends in failure when she momentarily steers in the wrong direction near the end of the corner, sending her into the wall. This leaves Andrew frustrated that everyone failed the challenge, and even more so that Krystal was so near, yet so far from passing.
While the experts consider Daniella to be the overall best performer in this episode, and praise her for researching how to properly reverse a trailer in her own time, she admits that she still finds highway driving an immensely stressful experience, and isn't yet ready to graduate. Mike also doesn't want to graduate despite having done reasonably well so far, but is confident that he is not Canada's Worst Driver. Krystal likewise admits she shouldn't graduate, but doesn't believe she is Canada's Worst Driver and claims that Tyler is the worst of the group, something that Tyler himself actually admits might be the case.
For the second episode in a row, Mike is the only person to be shortlisted. Despite his wish to stay in rehab, the lack of any other feasible graduate and Tim's positive feedback about his performance in the highway drives between challenges sees Mike become the next graduate.
