Legal Question

[mishka]

Hello all,
So I found info on the legal amount of window tint for VA and MD: http://www.tintlaws.com/laws/VA/ ; http://www.tintlaws.com/laws/MD/ ;

But I have a weird question... So my car is registered in MD with MD plates. I live in VA and have a VA driver's liscense.
Does my car have to abide by only MD laws since it's registered in MD? If so, I do not have to abide by VA laws right?
(I'm referring to laws regarding headlights, window tint, modification, etc.)

Thanks all.
