Distracted Driving: In the first episode, Cam noted that distracted driving has recently taken over from DUI as the country's most common motoring offence, and since nearly all the drivers in rehab are guilty of somehow being distracted at the wheel on a regular basis (Tyler eats, drinks and smokes while at the wheel, Jason reads newspapers, and everyone else uses their cellphone while driving; Siham is the only one who consistently refuses to be distracted at the wheel, and as such is exempted from this challenge), the seven remaining drivers are each asked to drive a simple course in a Ford Mustang coupe while undertaking the task that causes them to be distracted. Santana causes a lot of damage to the course even while sending simple texts. Tyler does even more damage while drinking from a bottle of soda, and compounds the situation by losing the lid and spending time looking for it instead of looking where he's going; after his run ends, he admits that eating, drinking or smoking while flying a plane is punishable by instant revocation of a pilot's licence. Chanie causes a lot of damage to the course just finding her cellphone, before a dramatic accident happens when she actually takes a selfie, as the car runs over some foam obstacles at such high speed that it's launched several feet into the air and nearly flips over; while the crew did not anticipate such an accident, it nonetheless shocks Chanie into admitting how unsafe her love of selfies at the wheel really is, with her even admitting tearfully that were her son in the car, he could have been killed. Jason's run is much less dramatic, though he still causes a lot of damage both while eating a cupcake and reading from a drivers' handbook. George is asked to call his fiancée during his run, and she speaks to Andrew over the speakerphone, revealing just how much she's been trying to break his habits; he claims that he's now reformed, but neither his fiancée, Patrik nor Andrew believe him for a minute. Mariah doesn't take the challenge seriously, and laughs throughout the destruction she causes while simultaneously eating and driving; it's then revealed that Shyamala had a lengthy talk with Mariah the previous day, and concluded that she has a tendency towards self-destructive behaviour due to a severe lack of self-worth, which in turn appears to have roots in the fact that when Mariah was 12, her family was abandoned by her father.
Reverse Figure-Eight: In another frequent challenge, the drivers are each placed at the wheel of a second-generation Dodge Ram Campervan covered with a huge number of signalling lights, and tasked with reversing around a course shaped like a figure-eight, with the other drivers as their passengers. Mariah quickly sets off without bothering to adjust her mirrors (and doesn't even use them anyway), and ends up hitting 13 objects, with her run doubly deemed a failure because she again didn't make a serious effort. Chanie ends up hitting 32 objects due to her inability to understand front-end swing. Tyler puts the other drivers at ease with a mock preflight announcement, but like Chanie he doesn't understand how to counteract the front-end swing, leading to a similarly poor run in which he hits 25 objects. George hits an object early on (earning himself another punch from Patrik, and one from Andrew for good measure), but quickly gets it together and doesn't hit another thing during his run, which he finishes even faster than Andrew did in his demonstration. Santana fails to adjust or use her mirrors early on, but picks up the technique and doesn't hit anything after the first corner. Before Jason's run, it's revealed that he was sent for an eye examination the previous day, which found that his bad eyesight is caused by a combination of early-stage glaucoma and some nerve damage caused by excess pressure on his eyeballs. In fact, his eyesight is so bad that the attending optometrist says he is obligated to contact the Ministry of Transportation with this information, which may lead to Jason's driving licence being put up for review. In the meantime, Jason takes the challenge, but even with his new glasses he hits 17 things; a poor performance, but one he admits would have been far worse without the glasses. Siham has the final run, and her extreme anxiety causes her to give up after the first corner. Andrew therefore takes her for a private lesson elsewhere in the rehab centre, teaching her proper mirror usage.
Cadillac Challenge: The Shoulder-Check Challenge: After the drivers each get a lesson from Philippe in proper driving posture, they are each tasked with driving up a lane at a fixed 70 km/h, and then shoulder-checking two towers to see whether they will be required to turn left or right around an obstacle at the end of the lane. Each driver gets two attempts. Siham has the first run, and correctly shoulder-checks, but leaves it too late to change lanes and hits the obstacle; on her second run she turns the wheel while shoulder-checking and hits the barriers bordering the lane. Tyler also turns too late in his first run, and swerves around erratically on his second, failing both attempts. Mariah passes with ease on her first run. Chanie doesn't even understand what a blind spot is, and on her first attempt she turns the wheel while shoulder-checking, causing her to hit the barrier and the obstacle; on her second run she turns what would otherwise have been a pass into a fail by braking sharply, and then gets into an argument with Jeremy, trying to deny that she did so. George fails his first attempt by turning too soon, and then fails his second go by turning into the wrong lane, getting more punches from Patrik and Andrew as a result. The experts are hopeful that Jason's glasses will help him greatly in this challenge, but these hopes quickly evaporate when he turns the wheel while shoulder-checking and consequently clips the barrier, along with failing to even drive at the required speed. On his second run however, Jason passes with ease, much to his and Bart's joy. Santana has the final run, and performs flawlessly, passing on the first attempt.
Most of the drivers tell the experts without any hesitation that they will never drive while distracted again, and Jason also reveals that he's going to wear his glasses full-time from now on. However, while Mariah vows never to drink-drive again, she won't commit to also giving up the use of her phone while driving. The biggest concern is Siham's defeatist attitude, as she openly admits that she isn't overly concerned whether or not she continues to drive, and refuses to commit to making herself a better driver.
Every one of the experts has a different opinion on who should leave rehab; Tim is in favour of expelling Siham for showing no desire to learn, Shyamala doesn't feel anyone should graduate, Philippe feels that now that Jason has glasses it's safe to return him to the roads, Cam says that George is the most technically skilled and should be given the graduation he missed out on last time, while Andrew wants to graduate Santana for showing the best attitude and passing both of the challenges this episode. Andrew is eventually able to convince the other judges to back his fellow Newfie, and Santana becomes the second graduate of the season.
