I was in my first accident when I was 17 I think. It was no-fault, but if the cop looked around and saw that there wasn't a left-turn arrow, it would have been his fault. $200 damage to his Pathfinder and $2500 to my Mustang. Fixed it for $500, juckyard are great!
I then got a ticket for 67 in a 35 in a "Agressive Driving Enforment Area" about a month later. That one really hurt. Then about 3 warnings for wreckless driving and showing off in about 6 months.
I've been clean for the past 7 years. I still drive like a bat out of hell, it's just more cautious.
Some advice if you're ever in a accident, take pictures. Pictures of everything. Lights, skid marks, damage to both vehicles, everything. If it's in the police report, it needs a picture.
