Kourtney Kardashian Says She Was The 'Accident Queen' On 'When I Was 17'

'I was always terrified driving in the car with her,' Kourtney's friend admits.

Admittedly, Kourtney Kardashian had yet to learn the rules of the open road back when she was a teenager. The oldest of the Kardashian sisters talks all about her not-so-great driving skills on "When I Was 17," airing Saturday at 11 a.m. on MTV.

Looking back on it, she said of all her sisters, she had to work the hardest to become a safe driver. "I was definitely known as the accident queen in my family," she says on the show, which also features Travie McCoy and "American Idol" winner Kris Allen this week. Kourtney's sister Khloé was already featured on the show earlier this season when she talked about her "shady kid" past.

Kourtney's mom, Kris Jenner, confirms on the show that "Kourtney Kardashian is the world's worst driver." Her pal Samantha also makes an appearance in the episode, adding, "She ran a ton of red lights. I was always terrified driving in the car with her."

The "Keeping Up With the Kardashians" and "Kourtney and Khloé Take Miami" star recalls one memorable accident. "When I was 17, I remember I was driving down the street, and the car in front of me stopped short, and I stopped really fast and I hit the car," she says. "I thought it was their fault, like I didn't know accident rules. So I was like, 'How dare you stop short even though I was driving like an inch behind you!' "

"When I Was 17" — this week featuring Kourtney Kardashian, Kris Allen and Travie McCoy — airs Saturday at 11 a.m. on MTV.
