The Guide to Legal Car Modifications in Nevada

The Guide to Legal Car Modifications in Nevada ARENA Creative /

If you live in Nevada or plan to move to the state and you have a modified vehicle, you need to know the laws and regulations to make sure your car or truck is considered street legal when you are driving on the roadways. The information below will help you understand the modification regulations for your vehicle.

Sounds and noise

Nevada has regulations that cover the sounds made by your vehicle.

Sound system

There are no limitations on sound systems in vehicles, or the level of noise that they produce.


  • Mufflers are required on all vehicles and must be in working condition to limit noise and pollution.

  • Muffler bypasses, cutouts and similar devices that amplify sound are not permitted on highways.

Tip: Also check with local county laws in Nevada to make sure you are following any municipal noise ordinances that may be more stringent than state-level laws.

Frame and suspension

Nevada does not have limitations on lift, frame or bumper height providing that the vehicle is not taller than 14 feet. However, there are body frame height restrictions based on Gross Vehicle Weight Rating (GVWR):

  • Less than 4,501 GVWR – Body height maximum is 28 inches
  • 4,501-7,500 GVWR – Body height maximum is 30 inches
  • 7,501-10,000 GVWR – Body height maximum is 32 inches


Nevada does not have any engine swap or modification regulations, but Washoe and Clark counties require emissions testing for annual renewals.

Lighting and windows


  • Two spotlights are permitted providing they are aimed in a way that the high-intensity part of the beam does not strike windows, mirrors or the windshield of another vehicle on the roadway.

  • Two auxiliary lamps are permitted.

  • Two fog lamps are permitted.

  • Two fender or side cowl lamps are permitted with amber or white light.

  • One running board light in amber or white is permitted on each side of the vehicle.

Window tinting

  • Non-reflective tint is permitted above the AS-1 line provided by the manufacturer.
  • Front side windows must allow over 35% of light through.
  • Back side and rear window tint can be any darkness.
  • Side mirrors are required if back window is tinted.
  • Reflective tint is not referenced or regulated in the laws.

Antique/classic car modifications

Nevada offers Classic, Classic Rod and Street Rod license plates. Classic plates and Classic Rod plates can be driven 5,000 miles per year.

  • Classic plates are for vehicles 25 years or older that have not been customized.

  • Classic Rod plates are for vehicles manufactured a minimum of 20 years prior to applying for the plates but not before 1949.

  • Street Rod plates are for vehicles manufactured before 1949.
