I agree that the BON probably doesn't care about traffic violations. In fact, our application (Florida) specifically says that they don't care about traffic offenses unless it was a DUI or something like that.
I had a bounced check that is considered a misdemeanor and I had to declare that. i didn't even know it bounced until I was served with court papers. I pled no contest and paid the fine. To be on the safe side, I declared it on my application, submitted copies of court documents, and wrote a letter explaining the offense. SO embarrassing!
The lady at the court said it probably wouldn't even show up on my background check, but better to be honest with the BON than to have it come up and look like you're trying to cover it up. I'm still kinda nervous about it, though.
