I have to agree with Andy here. Screw the MVA
It is the car that is insured not the tags, if you sold the car there is no point in keeping the insurance on it until you can turn the tags in. Some people have jobs to attend so they can pay the outrageous prices for tags in the first place.
The law has been around at least since the 80's when they tried to get me for the same thing. At that time it was only $5.00 a day over 30 days.
I took them a bill of sale and they let the fine go.
I was a kid and was ignorant to that law, there was only the Waldork MVA. Nothing in St. Mary's at all.
I guess they have gotten a bit more strict since then though.
It would still just piss me off to have to give them any more of my money really.
Also in the 80's they wouldn't allow you to re-register that car until the fine was paid, but if it was sold who cared?
