2 for parking, one was bad signage, which I beat after taking photographs of the sign and taking them to court. It was a residential handicapped sign that was so faded that you couldn't tell what it was, and it was mostly obscured by trees.
The other I was in a hurry, parked too close to the corner. I was hoping to get back out in time (I didn't)
1 - speeding, very early in my driving days, had a new (to me) car with a big engine (400 small block). When the cop asked me how fast I was going, I said I didn't know (lie). He said he clocked me at 65 in a 40. My response was "That's not bad"
