I don't know anything about jail time, but my dad used to be a city cop for Philly way back when. He told me when I registered the car here to do everything I could to get Veteran plates and it might help me. Since I have been to OIF a couple of times, I showed the DMV in VA my proof and they gave me OIF Veteran plates for Virginia.
Hopefully that will encourage them to not pull me over if I'm going 5-10 mph over, but I've also heard that the State Troopers couldn't care less, and they will jack me no problems.
Oh well
