The Drive to Rehab: Starting from a car lot in Niagara Falls, the eight drivers must drive themselves to rehab using a provided set of instructions, a journey that Andrew notes would take most drivers 90 minutes. Chanie is the first to set off, though Andrew is concerned when she admits that she does her make-up and takes selfies while at the wheel, and flabbergasted when she reveals that she isn't quite sure how to turn the car around in the car park. During the drive to rehab, she repeatedly runs red lights and illegally stops in a crosswalk. Jason sets off next, and his poor eyesight causes him to not only run red lights, but miss vital landmarks and street signs; upon his arrival at the rehab centre, Andrew tells him that they will be booking an eye test for him as soon as possible. Siham has to take anti-anxiety medication (which she indicates she usually does three times per day) before starting her drive, which goes without any major incidents or errors, though she's still incredibly nervous throughout; upon arrival, she makes the same vow that the previous season's "winner" Kevin Simmons did, by saying that should she be named the worst, she will destroy her driving licence and give up driving. Tyler has the opposite problem to most of the other drivers, proving so over-cautious that he frequently stops at green lights. Santana, on the other hand, frequently runs red lights, and her admission of repeatedly hitting things in her hometown results in Andrew admitting that his fellow "Newfies" don't always know how to drive. Ian becomes the show's first driver to drive to rehab in a taxi, and during the drive, Adam calls him out for using excuses to dodge responsibility for his errors, though his drive otherwise goes without incident. Andrew is concerned about not only Mariah's lackadaisical attitude prior to her drive, but Jessica's as well; Mariah subsequently insists on holding onto the directions herself while driving, runs red lights, and even drives the wrong way up a one-way street. George is the final driver to set out for rehab, and during his journey he drives well over the speed limit, texts while driving, and deliberately tailgates other drivers; he arrives in the fastest time in a little under 90 minutes, but this was because he disregarded the instructions and used his smartphone's GPS, causing Andrew to tell him that in future he needs to do what the show tells him to do.
Cadillac Challenge: Basic Assessment: This season's recurring challenge car is revealed to be a high-performance Cadillac CTS-V that the show purchased for $60,000. The basic skills test is identical to the one used in the previous season, with the drivers first having to reverse through a small course made up of wheel rims, then turn the car around in a space bordered by concrete blocks, and finally drive a high-speed slalom. Santana is the first to take the challenge, and her failure to adjust the mirrors (even after Jim-Bob reminds her to do so) results in her knocking down several rims, then badly denting and scraping the Cadillac while turning it around, before she takes the slalom and hits one of the four foam people. Tyler does even worse thanks to not using his mirrors at all, knocking down more rims than Santana, doing a similar amount of damage to the car while turning it around, and then going too slow in the slalom and still hitting two of the foam people. Things get even worse in Mariah's run, as she performs near-identically to Tyler, actively refuses to use her mirrors despite both Andrew and Jessica reminding her to do so, and gets extremely stressed out. George manages to break the trend, getting through the first two segments of the challenge without hitting a single thing; this causes Andrew to conclude that George's problem is with his attitude rather than a lack of skill, something demonstrated when he speeds in the slalom and hits the last foam person. Chanie hits the very first set of wheel rims, and then hits so many more that she actually punctures one of the Cadillac's tires. After the tire is replaced, she hastily goes through the concrete section and actually hits the blocks hard enough to move them around, before cementing this as the worst run yet by hitting several foam people in the slalom despite driving at barely half the required speed; on closer inspection it's revealed that she repeatedly hit the brake rather than the accelerator pedal in the slalom. Jason somehow manages to do even worse, knocking down nearly every set of wheel rims on the left-hand side of the initial section, then causing further damage to the Cadillac's body while turning it around, and taking the slalom at half the required speed. Ian proves to be incredibly slow, and still knocks down many wheel rims and then causes many dents and scrapes while turning around, before going too fast in the slalom and hitting two foam people; Andrew also points out that there are no formal requirements to becoming a taxi driver in Ontario other than a $150 additional licence, and to further make his point attaches a magnetic "Taxi" sign to the Cadillac's roof early in the run (which Ian doesn't even notice). Siham is the final driver to take the test, and in an effort to boost her confidence, Andrew asks her to take the first part of the test without Wayne in the car; she subsequently gets through the wheel rims without hitting a single thing, but when Wayne gets back in the car for the next part she immediately starts relying on him to make all the decisions, resulting in her having serious problems turning the car around, and then hitting two foam people during the slalom.
After the initial test, the drivers have their first meeting with the experts. The experts re-iterate to Jason the importance of taking an eye test as soon as possible, and Andrew expresses disbelief at the fact that driving-related eye examinations are not mandatory until the age of 80. Mariah is also called out on her attitude toward her drink-driving, and Cam informs her that should she kill or injure someone while doing so, she would face near-certain jail time. Most of the drivers are convinced that they are not Canada's Worst Driver, though Jason, Chanie and Siham admit that they may be.
As in nearly all of the show's first episodes, no-one graduates.
