Well that's one to check on, I can't believe it's really a tow if you have the back plate with current stickers on it, geesh.
In 7 years of driving with no front plate on 2 vehicles at any given time, I've gotten one, a MD state trooper who drove across an interstate median into fast lane traffic to get me in the slow lane. Funny thing was, I was on my way to the track in my 2000 RT/10, had the helmet on the seat - although our cops are usually decent from my exp, this guy was a **** and a half - he was barking at me & asked why i had a helmet in the car - told him I only drive fast at the track, hence my under the speed limit pace while I was heading to the track. That kinda shut him up, but cost me $50 bucks. Towing would be crazy.
