I have never gotten one...yet. I do sometimes speed, but it's rare and usually on a stretch of high way that is taking too long to get through.
I did get pulled over when dd2 was a baby. A police car in front of me failed to use their turn signal and they made a sudden right turn right in front of me. At the same moment dd1 picked up a yellow pool floaty and waved it around and I saw this giant yellow thing in my rear view mirror which surprised me, I almost rear ended the police car! They did a U-y and followed me and pulled me over a block away and made me sit for 30 minutes with 2 screaming babies in the back seat. THEY Failed to signal!!! I was livid. And because I said I didn't know why he pulled me over and gave him a small piece of my mind about using turn signals he let me off with a warning.
He was in the wrong and I think he also felt a little bad once he saw I had 2 small ones screaming for food (it was lunch and nap time and we were literally 2 minutes from home). I still get angry when I remember that awful experience.
