Jenner told Today host Matt Lauer she has "very little" memory of what happened but said she will never get over the tragedy.
"A tragedy like this, you'll never get over it. You just learn to live with it the best you possibly can."
While she doesn't remember the details of the crash, Caitlyn insists she wasn't speeding.
"I was under the speed limit, I was going 46 in a 50 - my air bag didn't even go off."
Elsewhere, the former Olympian admits she feels lucky to have experienced life as both male and female.
She said: "I think about my life and where I'm at in my life right now and what a tremendous experience this.
"Hardly nobody gets to live two genders in their lives. Everybody wonders, 'Oh, what's it like to be coming from the other side? You know, their thinking, the way they act, everything?' And here I have the opportunity to do that. And to be honest with you, everything's so new and fun. From that standpoint, it's been great."
