The Drive to Rehab: As always, the first challenge for the drivers is to drive themselves to the Driver Rehabilitation Centre. Typically, many moving violations and other faults are committed along the way. Michael runs a stop sign only minutes into his drive, and continues to demonstrate his habit of holding his breath in tunnels, though his driving was not helped by Yolanda’s nagging. Shelby, in stark contrast to his slow driving in Canada’s Worst Driver 3 actually breaks the speed limit more than once, though otherwise makes it to rehab without incident. Dale keeps stopping at green lights, and then hits the barrier when parking up. Sly runs two stop signs due to not even knowing what they’re supposed to look like, causing Andrew to re-iterate his belief that Sly was really the worst driver from his season, and should give up driving completely. Kevin fails to compensate for his limited vision and nearly collides with a truck; upon reaching rehab, he tells Andrew that should he be named Canada’s Worst Driver Ever, he will surrender his driver’s licence and sell his car. Shirley, despite the confident predictions of Janis and Andrew that she will do well this season, makes a careless mistake and nearly drives into an occupied intersection, having to be stopped from doing so by Janis. Among all of these errors, a special dishonour is earned by Angelina, who becomes the show’s first-ever driver not to even be able to attempt to make the drive to rehab, as she spent the previous night drinking heavily and is visibly hung over, leading to Chris volunteering to drive Angelina and Christine to rehab. Chris’s own drive goes completely without incident, only having to stop once so that Angelina can vomit. Henrietta’s drive also goes much smoother than she or Andrew had predicted, though she was still nervous throughout.
Camaro Challenge: Basic Assessment: After revealing that this year’s recurring challenge car will be a Camaro SS (painted in a flag-inspired livery), Andrew walks through the basic assessment that each driver will undertake. The challenge itself is basically the same as the one from Canada’s Worst Driver 8, albeit with the first two sections flipped around; firstly reversing through a course of wheel rims, followed by a U-turn in a section of concrete barriers, and finally a slalom between foam people at 50 km/h. Angelina is first-up and gets off to a predictably bad start, knocking over a set of wheel rims before Andrew can even finish his introductory speech. Despite Christine’s best efforts to guide her, she knocks over nearly every set of wheel rims, dents and scrapes the Camaro in the U-turn, and then her wedge shoes get stuck on the accelerator in the slalom, causing her to drive at an inconsistent speed and hit most of the foam people. Dale’s run is near-identical to Angelina’s, as she never uses her mirrors in the reverse segment, causes even more damage to the car’s bodywork in the U-turn, and goes significantly under-speed in the slalom. Kevin does even worse than the previous two drivers, not using his mirrors once in the reverse section (which takes him over 20 minutes to complete), nearly tears off the Camaro’s front bumper in the U-turn, and then goes completely off the course during the slalom. Henrietta does a little better than the previous drivers in the first two segments, albeit with extensive coaching from Andrew and her husband Andy, but goes under-speed in the slalom and hits several foam people. Chris has by far the best run of the day, not knocking down a single wheel rim, only experiencing a very low-speed collision in the U-turn, and then executing the slalom flawlessly. Sly’s main issue in the reversing section, surprisingly, turns out to be being over-cautious; he completes it while only knocking a few rims down, but takes more than half an hour to do. His run rapidly falls apart in the U-turn, however, as he rips off the Camaro’s rear bumper, then drives with only one hand on the wheel in the slalom, going far too wide and completely missing the required turns. Michael does quite well in the reverse section, only hitting three rims, but then seriously bumps and scrapes the car in the U-turn, before trying to take the slalom at 80 km/h and violently spinning off-course, which reduces Yolanda to tears. Shelby, in a more familiar turn of events, is the slowest performer of the day, taking over 40 minutes to complete the reversing course (though he hits fewer rims than many of the other drivers). After that, he can’t even complete the U-turn and so is allowed to bypass to the slalom, where his repeated under-steering causes him to fail. Shirley initially struggles in the reversing course due to trouble aligning herself correctly, but soon picks it up, then executes the U-turn flawlessly, but like Shelby, under-steers on the slalom and fails, though is still the only driver apart from Chris to successfully complete any of the segments..
The drivers then have their initial meeting with the experts. Michael asks Philippe to go over the footage of his slalom spin-out with him, and Philippe tells him his mistake was driving too fast and not looking where he wanted to go, instead directly staring at the foam people. Sly is also called out for making the same mistake in his run. Henrietta admits that since Andy retired shortly after Canada’s Worst Driver 2 aired, he usually drives the couple everywhere, and she doesn’t usually drive more than a dozen times per year. Shelby thinks he might be Canada’s Worst Driver Ever; Andrew tells him that he probably isn’t that bad, but that he could still benefit from more rehab (Shelby also expresses shock that Angelina really is as bad as her reputation suggests). The remaining drivers all deny that they may be Canada’s Worst Driver Ever.
Due to the exceptionally awful performances by most of the drivers, the experts agree to graduate one person immediately so as to give the remainder their full attention, and very quickly decide on Chris. However, Cam raises the issue that Henrietta would not realistically benefit from rehab, since she drives so rarely, and that they would be better served sending her home and focusing on the remainder. Ultimately, Andrew gives Henrietta her licence back, after which Andy drives her away. Andrew then further surprises the drivers by announcing that Chris, clearly the most skilled of the group, will be the first graduate.
