The reality TV star, who is pregnant with her second child, was travelling in Montana with her daughter North West, sister Khloe, and half-sister Kylie Jenner when their vehicle skidded on black ice, spun into oncoming traffic and crashed into a ditch.

The occupants of the car were uninjured, but Kardashian admits the accident terrified her and she has now promised to obey the law and wear a seat belt at all times.

In a series of posts on Twitter.com, she writes, "I honestly couldn't believe we had car cams on when that happened!!!!! How scary was that seriously!!!!!!!!! I always wear my seat belt now!.. I don't even know why I started crying after! Just so happy everyone is ok! Scariest experience of my life!... The crash was so scary... As a mother this as the scariest things that could have happened w (with) your child in the car... If u (you) only saw Northie's reaction! As a mom I got protective and left that scary moment out of the episode for her privacy."
