Expungement & Traffic
If you never dealt with the ticket you also have a failure to appear- which is a misdemeanor added to the ticket. If you get stopped you could get arrested. I would suggest hiring an attorney to deal with the warrant and ticket. You can always check online with the court or go to the DMV and get a printout of your record.
