It is the longest running of any Worst Driver series to date with 14 seasons and 115 episodes (assuming specials are included).

[b] The first episode concludes with an obstacle course challenge – meant to evaluate the skills of the individual drivers – in which contestants must routinely maneuver their cars through tight spaces with less than an inch of clearance on either side.

After all contestants are interviewed, the judges and host deliberate on which contestant–nominator pair have improved enough to graduate from the Driver Rehabilitation Centre.

Chris was the first person named Canada's Worst Driver due to his inexperience and lack of awareness on the road.

This season's worst driver was Henrietta Gallant due to her vision issues and her insistence on not wearing glasses, along with being unable to complete the final road test.

This season saw the first-ever expulsion in any Worst Driver series when Colin Sheppard was expelled due to his unwillingness to learn.

Jason was named Canada's Worst Driver for his dangerous final road test performance – stopping in the middle of merging onto Ontario Highway 400.

As a result, Jason immediately surrendered his license and gave up driving permanently, the first contestant ever to do so, which made runner-up Shelby D'Souza technically the worst by default.

Despite passing most of the challenges and being shortlisted four times, including three episodes in a row, Ashley was named Canada's Worst Driver for her emotional instability at the wheel and for having never addressed her frustrations with her husband and nominator, Bryan.

Angelina was named Canada's Worst Driver due to her severe anxiety and lack of focus.

This season saw the first time a contestant left due to a personal tragedy, as Crystal Hubley Farao's brother-in-law, Tom Stagno, was killed in a traffic collision when another driver failed to yield the right-of-way.

Despite performing well in most of the challenges this season, Shirley was named Canada's Worst Driver after a disastrous final road test that included stopping while merging onto, and attempting to exit, the Chedoke Expressway.

Kevin was named Canada's Worst Driver Ever after turning in an even worse final road test than the previous season.

Afterwards, he burned his license under the promise he'd made to the panel and his boyfriend and nominator, Lenny Stone, that he'd stop driving if he either didn't graduate or was named the worst ever.

This season saw the first time a contestant graduated in the first episode (as Chris Ferguson was the only returning driver to pass the assessment challenge), another contestant was disqualified and removed from the show due to the experts judging Henrietta Gallant ineligible to take part (Henrietta admitted she largely gave up driving after previously being named the worst) and another contestant's nominator was replaced (Yolanda Kozak served as Michael Telford's nominator after his original nominator, Eric, was unable to return for health reasons; he had since recovered to replace her in the fifth episode after she was proven to be too negative and detrimental).

Self-described "Selfie Queen" Chanie was named Canada's Worst Driver for her lack of focus at the wheel and for admitting to driving without her legally-required medication.

Despite passing some challenges and numerous practice driving sessions in public off-camera, Jillian was named Canada's Worst Driver due to her inability to completely overcome her anxiety when alone behind the wheel, deemed by the judges to be a real danger to other drivers on the road.

Krystal was named Canada's Worst Driver due to her to her cell phone usage, aggressive driving, and mood swings.

Brandon was the final person ever given the title of Canada's Worst Driver (replacing season 4 "winner" Ashley van Ham as the youngest) due to his reckless driving, emotional instability and lack of basic understanding of road signs and rules.

This season also marked the only instance of a new contestant graduating in the first episode, as Ryan Whittier drove perfectly in the Assessment Challenge, while Brandon had to get a doctor's note after arriving at rehab to get permission to be able to drive since he broke his arm in a skateboarding accident a week before filming.

The location of the Driver Rehabilitation Centre and of the final road test have changed throughout the show's run.

Season 4 was filmed at the site of the Ontario Reformatory Prison, an abandoned correctional facility in Guelph that closed down in 2002 due to being too harsh.

In season 5, the series returned to CFB Borden (referred to on-air as "an undisclosed military location") while the road test continued to be in Toronto.
