Iam going to be moving to Sparks, NV the first week of june. How are the laws like about registering vehicals? are they enforced regularly? are their inspections? if so what kind??

I have really dark tint on both my trucks, is this going to be a problem?

Only if it's a Nevada vehicle already, there will be no inspection. To register an out of state vehicle, you will need an inspection, proof of ownership, valid smog cert. and I believe proof of ins. I have 5% tint (they say it's illegal) and have never been messed with but the truck has never been inspected either. If they make you take it off, they make you take it off.
