2026 Maximum Smog Check Fees in Clark County
Smog check stations set their own prices up to the Nevada DMV’s annual maximum. Many offer lower prices or discounts. Every licensed station must post its testing fees.
| Vehicle Class | Inspection | Certificate | 2026 Maximum Total |
|---|---|---|---|
| Light-duty gasoline, up to 8,500 lbs. | $68.50 | $7.00 | $75.50 |
| Heavy-duty gasoline, 8,501 lbs. or more | $68.00 | $7.00 | $75.00 |
| Diesel, up to 14,000 lbs. | $83.00 | $7.00 | $90.00 |
These are legal maximums, not typical advertised prices. A station that processes a registration renewal may charge up to $10 more for that service. Confirm the complete price, including the certificate fee, before testing.
Who Needs a Nevada Smog Check?
A vehicle generally needs an annual emissions test when all applicable conditions below are met:
- It is based in the designated urban emissions-testing area of Clark County.
- It is a 1968 model year or newer.
- It is gasoline-powered, regardless of weight, or diesel-powered with a manufacturer’s gross vehicle weight rating of 14,000 pounds or less.
- It is not covered by a new-vehicle, hybrid, geographic, fuel-type, classic-vehicle, or other statutory exemption.
Testing is required throughout the Las Vegas Valley and surrounding testing buffer. Some outlying Clark County communities are exempt. If you are unsure whether your address is inside the testing area, call the Las Vegas DMV Emission Lab at (702) 486-4981.
Vehicles That Are Generally Exempt
- New vehicles during their first three registrations; testing begins with the fourth registration
- New hybrid-electric vehicles during their first five model years; testing generally begins in the sixth model year
- Fully electric vehicles, also called battery-electric vehicles or BEVs, regardless of model year
- Vehicles from model year 1967 or earlier
- Motorcycles and mopeds
- Vehicles permanently powered by propane, compressed natural gas, methane, or butane
- Diesel vehicles with a manufacturer’s GVWR of 14,001 pounds or more
- Vehicles based outside Nevada’s designated emissions-testing areas
- Qualifying Classic Vehicle, Classic Rod, Old Timer, and Replica vehicles that meet the DMV’s plate, insurance, mileage, and annual-documentation rules
Some ownership or registration transfers also qualify for an exemption from obtaining a new test when a recent passing test is still valid.
Exemptions have conditions. Review the Nevada DMV Emission Control Program before relying on one.
Do Fully Electric Vehicles Need a Smog Check?
No. Fully electric vehicles are exempt from Nevada emissions testing, regardless of age. This includes battery-electric cars, SUVs, and trucks. Because they do not have gasoline or diesel engines, they produce no tailpipe emissions.
Popular examples include fully electric Tesla vehicles, the Nissan LEAF, and other battery-electric models.
However, not every vehicle that uses electricity is exempt. Plug-in hybrids and conventional hybrids also have gasoline engines, so different rules apply.
| Vehicle Type | Nevada Emissions Requirement |
|---|---|
| Fully electric (BEV) | Exempt regardless of model year |
| Plug-in hybrid (PHEV) | Generally requires annual testing after the five-model-year hybrid exemption |
| Conventional hybrid (HEV) | Generally requires annual testing after the five-model-year hybrid exemption |
| Gasoline-only vehicle | Generally requires annual testing after the first three exempt registrations |
Fully electric vehicles must still meet Nevada’s registration, insurance, and applicable odometer-reporting rules. The emissions exemption does not eliminate those obligations.
How to Prepare for a Smog Check
- Check the warning lights. A flashing check-engine light can indicate a serious problem. Stop driving safely and arrange service. Nevada DMV advises owners with a steady light to complete the test because an official failure may be needed for a waiver.
- Tighten the gas cap. A loose or damaged cap can trigger an emissions-system fault.
- Do not test immediately after disconnecting the battery. On 1996-and-newer vehicles, the OBD system may need varied driving for up to a week to complete its readiness monitors.
- Make sure the vehicle is safe to test. Fix obvious exhaust leaks, overheating, severe misfires, or visible smoke first.
- Bring your renewal notice if you want registration service. Ask whether the station processes renewals and which payment methods it accepts.
A last-minute oil change, premium fuel, fuel additive, or coolant top-off does not guarantee a passing result. The test evaluates the emissions-control system, not a general maintenance checklist.
What Happens During a Nevada Smog Check?
For most gasoline vehicles from 1996 onward, the inspector connects approved equipment to the vehicle’s OBD-II system. The test checks emissions-system status, diagnostic trouble codes, the malfunction indicator lamp, and readiness monitors.
Older vehicles and certain heavy-duty vehicles may receive a tailpipe test. Diesel procedures differ by vehicle configuration.
The station sends the result electronically to the Nevada DMV and provides a Vehicle Inspection Report. A passing result is generally valid for 90 days. A test provided with a Nevada dealer sale is valid for 180 days.
If Your Vehicle Fails or Is Rejected
Failed Test
Use the Vehicle Inspection Report to identify the failure. Then obtain appropriate repairs and a retest.
If you may need a DMV waiver, review the waiver rules before choosing a repair shop or buying parts. The station type, repair documentation, timing, and qualifying expenses can affect eligibility.
A one-year waiver may be available only after an initial failure, qualifying repairs, and another failed test. Waivers are not available for vehicles that emit visible smoke, have tampered emissions equipment, or qualify for warranty-covered repairs.
See the DMV’s current failure and waiver requirements or call (702) 486-4981.
Rejected Test
“Rejected” does not mean the vehicle failed. It often means the OBD readiness monitors have not completed after a battery replacement, disconnection, code clearing, or recent repair.
Drive under varied conditions as recommended by the manufacturer, then return for testing. Do not repeatedly clear codes.
Expired Registration
If the registration is expired or about to expire, request a Nevada DMV movement permit before driving the vehicle on public roads.
Smog Free Clark County Repair Assistance
Qualifying Clark County residents may receive up to $975 toward emissions-related vehicle repairs through the Smog Free Clark County program.
The program has offered assistance for eligible vehicles from model years 1968–2010. Applicants must satisfy current program requirements, including income, ownership, registration, a failed smog inspection, and available funding.
How to Apply for Repair Assistance
- Obtain a failed emissions test. Keep your Vehicle Inspection Report. A rejected test is not the same as a failed test.
- Review the eligibility requirements. Check the current income, vehicle-age, ownership, and registration rules.
- Apply before authorizing repairs. Work performed before approval may not qualify for assistance.
- Follow the program’s repair instructions. Covered work may need to be completed at a participating authorized 2G emissions repair station.
- Complete follow-up testing. Follow the program’s directions for retesting and documentation.
Program phone: (702) 805-5882

Assistance amounts, eligibility rules, and available funding may change. Contact the program and obtain approval before scheduling covered repairs.
Nevada Smog Check FAQs
How often do Las Vegas vehicles need a smog check?
Qualifying vehicles require emissions testing every year. Nevada does not use a biennial testing schedule for these vehicles.
Do fully electric cars need a smog check in Nevada?
No. Fully electric vehicles, also called battery-electric vehicles or BEVs, are exempt from Nevada emissions testing regardless of vehicle age. They have no gasoline or diesel engines that produce tailpipe emissions.
Do plug-in hybrids need a Nevada smog check?
Generally, yes. Plug-in hybrids use both a rechargeable battery and a gasoline engine. New hybrid-electric vehicles are exempt for their first five model years. After that, qualifying vehicles generally need annual emissions testing in the designated testing area.
Do regular hybrid vehicles need emissions testing?
Yes, once the five-model-year exemption ends. Conventional hybrids, such as a gasoline-electric Toyota Prius, generally require annual testing beginning in the sixth model year when based in the testing area.
Do electric vehicle owners still need to renew registration?
Yes. A smog check exemption does not exempt a fully electric vehicle from Nevada registration or insurance requirements. Applicable odometer-reporting requirements also remain separate from emissions testing.
Does Nevada require electric vehicle odometer readings?
Nevada has operated an electric-vehicle odometer reporting program. Reporting obligations can depend on the registration transaction and current state rules. Check the Nevada DMV for the latest instructions when renewing an electric vehicle registration.
Does a check-engine light automatically prevent testing?
No. Nevada DMV advises drivers with a steady check-engine light to have the vehicle tested because an official failure may be needed for a waiver. A flashing light indicates a serious malfunction. Stop driving safely and arrange service.
How long is a Nevada smog test valid?
A passing emissions test is generally valid for 90 days. A qualifying test provided with a Nevada dealer sale is valid for 180 days from the test date.
Is a Nevada smog test required for a private-party vehicle sale?
A passing test is generally valid for 90 days. In a private transaction, the buyer is responsible for obtaining a required test. An existing valid test may satisfy the requirement. Nevada dealers must provide a qualifying vehicle with a passing test valid for 180 days from the test date.
What is the difference between a 1G and 2G station?
A 1G station performs emissions testing but not emissions-related repairs. A 2G station can perform testing and authorized emissions repairs. Use a 2G station when the DMV’s waiver rules or a repair-assistance program require qualifying repair work.
Can a smog station renew my registration?
Some licensed stations can process eligible registration renewals after the test. They may charge up to $10 in addition to the emissions-testing fee. Ask before testing and bring your renewal notice.
How can I find the cheapest smog check in Las Vegas?
Compare published prices and the coupons and discounts near the top of this guide. Ask whether the advertised price includes the Nevada certificate fee and whether it applies to your vehicle.
Are Las Vegas smog check stations open on Sunday?
Some are. Super Smog One and 24/7 Xpress advertise Sunday testing. Always confirm current hours before visiting, especially on holidays.
Can I use a Groupon for a Nevada smog check?
Some local stations accept Groupon vouchers. Check the participating location, vehicle restrictions, expiration date, certificate inclusion, and extra charges before buying.
How do I report a smoking vehicle?
Use the Nevada DMV Smog Spotter form or call 844-END-SMOG.
