I've been pulled over 3 times and have been ticketed twice. I got those taken care of though
The one time I was given a warning was the first time I was stopped. I was going 40 in a 25. It had just changed to 25 from 35, and I told the cop I was sorry and didn't see the 25 sign.
The next time I was stopped, I was going 45 in a 35 but got it taken care of.
The last time I was pulled over, I was going 45 in 45. The cop thought it was a 35 and gave me a ticket. I went back to see if it was 35, and sure enough it was 45. I got that one take care of pretty quickly.
