In this episode, the experts decide to address the contestants' difficulty with regards to merging into traffic.
Shoulder Checks – In a new challenge, the contestants must accelerate their car up to 60 km/h before encountering a sign. After reading the sign by shoulder checking, they must take the correct exit at a fork in the road. Contestants have five attempts, failing if they fail to make the shoulder check, making the wrong exit, or hitting any obstacle. Teagan tries to cheat by removing his head restraint (though with it he passes on his third try), while Lindsay learns to "watch the road" when she passes on her second try (no one passes on their first try, while Ashley is the only other contestant to pass on her second). Emily, who is too vision-impaired to drive without glasses, makes it on her final attempt, but it is later discovered that she guessed an exit at random and had guessed right. Donna is too scared to go up to 60 km/h, and she even failed a run at 50 km/h (but did pass a 30 km/h run). Amy fails all five runs, but discovers that while making the shoulder check, she drifts her car to the right to overcompensate a natural leftwards drift when she turns her body.
The Traffic Circle Challenge – In this challenge, the contestants must drive a Jaguar and enter a traffic circle and pass six cars (two in the inner lane driving around at 15 km/h the other four in the outer lane at 25 km/h) before exiting, without exceeding 30 km/h in any part of the run. Ken finishes in four minutes with John barking orders at him, so when Andrew (driving the fifth car in this challenge) goes into the passenger seat (and have John in the fifth car), Ken finishes with a perfect run (including full lane change signalling, something he does not do at home) in three minutes. Teagan finishes without passing the sixth car, failing the challenge, while Amy, frightened by the challenge, cries her way through a perfect run in nine minutes. Ashley screams through her run, but manages to learn how to use her mirrors. Emily also passes with ease, while Donna has her left blinker on despite being in the inner lane. Lindsay also fails the challenge, as she does not do a full check in four of her lane changes.
Road Signs – Every year there is a quiz for all contestants on their knowledge of road signs. Of the 15 road signs tested, Amy has the most correct with 7, and Donna is worst with 3.
Public Lane Change – The contestants are put out onto public roads, where they must make 15 safe lane changes, as determined by her nominators. Lindsay is first to finish, while Ashley finds herself having driven with the parking brake down for half an hour, and needs to get her car towed away. Emily and Amy are driven to the edge, but eventually finish. Donna runs into her old habits of running past stop signs, while Ken does not run into his old habits, even admitting to Andrew that the "old Ken" would have cut off others on a number of occasions.
At the end, Emily admits to needing more rehab, while Amy, Teagan, and Donna are told that they will not graduate this episode. The experts and Andrew are deadlocked, though: Dan and Cam are willing to overlook Ashley's parking brake incident, while Ken has taken rehabilitation to heart (even admitting that he is doing this for his quadriplegic wife), which, in Dr. Gembora's and Phillipe's eyes makes him the best driver. Andrew, however, places his vote behind Lindsay, but is pressured by the experts to change his vote and break the tie between Ken and Ashley. Thus, Andrew chooses Ken to be the next graduate.
