Nevada window tint laws

For a sedan in Nevada, front side windows must let at least 35% of light through, no number is stated for the back side windows, and none for the rear window. Lower VLT means darker glass, so those percentages are floors, not targets, and the meter reads the film and the factory glass together.

No, not on the front side windows. Nevada requires at least 35% VLT there and 20% is darker than that, before you even account for the factory glass, which makes the reading darker still. Behind the driver the statute states no VLT number, so 20% may be allowed on the back side and rear windows — read the notes on this page and confirm with the DMV.

Nevada's rule for the windshield: Transparent material may be applied only to the topmost portion of the windshield, and only if the bottom edge of the material is at least 29 inches above the undepressed driver's seat (measured from a point 5 inches in front of the bottom of the backrest, seat in its rearmost and lowermost position, vehicle on a level surface) and the material is not red or amber in color. Nevada uses this 29-inch measurement — NOT an AS-1 line.

What the source says: Yes. NRS 484D.440(6) authorizes the Director to provide exemptions by regulation, and NAC 484D.280–.290 implement it: a written application to the Nevada Highway Patrol stating the percentage of total light transmission, plus a physician's sworn statement that the applicant has a medical condition requiring tinted windows and the applicant's sworn statement that he or she is the primary driver. Parallel exemptions cover vehicles operated as an ambulance or hearse and law-enforcement vehicles used for surveillance, canine transport, or forensic purposes. Owners of vehicles with a GVWR of 10,000 lbs or more subject to 49 C.F.R. 393.60(b) may not apply. Confirm the current process with the agency named before you have film installed.
