LOL! Funny that you say that Leslie! We have plenty of Maine plates runing around down here in Connecticut. Turns out a few years ago our safety inspections got real hard for some clunkers to pass. So these folks discovered that you can register a vehicle in Maine without a safety inspection and you DON'T need a Maine address!
You mail in a check to the Maine DMV with your registration and they'll mail you back a set of license plates to Connecticut! The don't care if you're not a resident! And trust me, these old clunkers in the worst section of town are not folks with Maine vacation homes! LOL.
Maine shouldn't allow this, but they must like the money it generates. Connecticut DMV is furious at this, but they can't just pull over every car with Maine tags! So they expect people to report their neighbors if they are doing this. Yeah! right!
We can't make such creative plates here in CT. We can't mix letters and numbers unless separated by a dot. We don't have any of these "! @ # $ % & * +" symbols either. (New Hampshire lets you use those too.) Connecticut has strange vanity plate rules. We are limited to six characters too.
