Smog Test

Get Your Smog Test at Doctor Auto

Nevada requires smog inspections for many original vehicle registrations and for every annual renewal. When you receive your renewal notice, it will state if your vehicle needs testing. Your emissions test is valid for 90 days. 

Important Notice on Batteries: If you drive a 1996 or newer vehicle and have disconnected the battery for any reason, don't go for your smog test right away. For the On Board Diangostics system to run all tests, your vehicle needs to be driven under varying conditions for up to one week with the replacement battery. Otherwise, it will be “Rejected.”

Doctor Auto serves the smog and emission test needs of Las Vegas, NV, North Las Vegas, NV, Henderson, NV, and surrounding areas.

Does My Vehicle Need a Smog Test?

Smog tests are required for passenger cars, trucks, RVs and motor homes if they are:

• Based in the urban areas of Clark or Washoe county;
• Gasoline powered (regardless of weight or size)
• Diesel powered with a manufacturer's gross vehicle weight rating up to and including 14,000 pounds; and 1968 model year or newer
• New vehicles on their third registration. First and second registrations are exempted. Hybrids are exempt for five model years.

For exempt vehicles, see the Nevada Department of Transportation website.
