No, it is not illegal. New Mexico does not require a front state license plate.
To legally operate on a public roadway, all of them.
The state of Arkansas does not require you have a front license plate. You only need a rear plate.
NO - only if you are REGISTERED in the new state, and do NOT put a front plate on - for example, Pennsylvania and New Jersey. If your car is registered legally in PA ( Rear plate only) and you drive in to New Jersey, you can not be stopped for not having a front plate - only cars REGISTERED in NJ need the front plate.
It depends on what State the vehicle is registered in. Some States require only one plate.
That's typically going to depend on the state. Most states that do have a front plate require it to be permanently affixed to the front of the vehicle.
No, that could be considered obstruction of justice in some jurisdictions.
In N.Y. State you do. I would imagine that it would be the same in all states as the license plate light makes the license plate readible at night.
Contact your local highway patrol for that answer. Some municipalities require a sticker for vehicles also so be aware of that. The state of CT does not require an emission or registration sticker on the window or the licence plate.
