I've been in 4 car accidents (that I can recall).
The first one was in 2003, I would have been 7 or 6. My dad was driving us to school in my mom's Mustang, when we got hit head-on by a new driver in his mom's SUV. Our car was totaled and all of us sustained some kind of injury, though my sister got it the worst with permanent back damage and respiratory problems from the airbag (since she was in the front seat). I came out of it with a severely busted lip which still scars on the inside, and a large cut on my chin, but thankfully nothing serious.
The second one was actually my dad's fault. It happened about a year later and was, once again, while we were being driven to school. My dad got distracted by something, I think it was someone getting arrested, and missed the light ahead turning red. We slipped under the trailer of the semi in front of us. The front end of the car got pretty damaged, particularly the hood, but ended up being repaired and remained on the road for several more years, and none of us ended up getting hurt really at all. That accident was more of a large derp than anything.
The third one was much later, 2012 or 2013 I believe. I was staying at my mom's house and her next-door neighbour was unlicensed (which i wasn't aware of) and would borrow her car and pick her up from work. I went with him to pick her up one day and he panicked because he almost missed a left turn. As a result, he hastily swerved left to turn on what he thought was the right street (it actually wasn't) right into oncoming traffic. The passenger side got hit in the back by a motorcycle and the car was written off. Thankfully didn't get hurt from that, but got a stern talking to by family members for riding with an unlicensed driver (as if I was supposed to know).
The last and most recent one was the only one in which I've been behind the wheel. It happened during the summer of 2015 when I went out on the highway for a late night drive to take my mind off some things. It was around 4am and I was about 2 hours from home when I dozed off behind the wheel and drove off the road. Conveniently, there was an intersection so it ended up being not as serious as it could have been, but the car was still totaled. I drove over a concrete divider, then up onto an embankment and into a tree and the car tipped over onto the driver's side. I didn't get hurt but was really scared since I was out in the middle of nowhere by myself in the middle of the night. There happened to be a security guard passing by who saw me there a couple minutes after and I then phoned my dad to let him know what happened. Learned an incredibly valuable lesson that night and I am always extremely alert now as a result, even if I'm tired.
Aside from those, there have been several close calls, particularly with inattentive drivers in big cities, but I always manage to avoid anything serious happening.
As a result of the accidents I was involved in as a kid, I frequently get an intense anxiety whenever I am a passenger in a vehicle, no matter who is driving, though I've been slowly getting over it over the past few years. As a driver myself, I have learned my lesson and now I have a much better idea as to my limits and how to control my tiredness when I'm driving.
Accidents aren't fun and I like to believe I've been in more than most people in my life. They can be physically and psychologically damaging if not fatal and I see aftermaths of them far too often.
