Vehicle registration is a crucial aspect of car ownership, and in many areas, passing an emission test is a prerequisite for registration renewal. If your vehicle fails its initial emission test, it’s essential to understand the steps required to rectify the issue and ensure your vehicle is legally compliant. This guide outlines what you need to know if your car fails an emission test and how you might be eligible for a waiver to proceed with your vehicle registration.
If your vehicle has not passed its emission test, repairs are necessary for it to pass a subsequent test and become eligible for registration. Operating a vehicle with expired registration can lead to penalties and legal citations. For gasoline-powered vehicles, specific regulations apply, and for diesel vehicles, you should refer to specific guidelines such as the Diesel Emission Requirements flier.
Waiver Eligibility: When Repairs Aren’t Enough
Even after undertaking repairs, some vehicles may still fail an emission test. In such cases, a waiver might be an option to allow vehicle registration. However, specific criteria must be met to qualify for an emission test waiver.
Your vehicle may be considered for a waiver if it fails due to:
- High Emission Levels: Exceeding the acceptable carbon monoxide and/or hydrocarbon levels. This typically applies to 1968-1995 light-duty vehicles and all heavy-duty vehicles.
- “Check Engine” Light Issues: An illuminated “Check Engine” light in 1996 and newer light-duty vehicles indicates a failure that might qualify for a waiver under certain conditions.
However, waivers are not granted in the following situations:
- Warranty Coverage: Vehicles that are still under emission component warranty coverage are not eligible. Federal law mandates emission components to be covered for up to 8 years or 80,000 miles, whichever comes first. Refer to EPA Emission Warranty Coverage for detailed information.
- Smoking Vehicles: If your vehicle is visibly emitting smoke, it must undergo repairs to eliminate the smoking issue, regardless of the repair costs. A waiver will not be issued for smoking vehicles without proper repair.
- Emission Device Tampering: Vehicles with evidence of emission control device tampering must be repaired to restore the emission system to its original configuration, irrespective of the cost. Waivers are not provided for tampered emission systems without rectification.
It’s important to note that an emission waiver is valid for only one year. The vehicle must be properly repaired before the next registration renewal to pass the emission test.
County-Specific Waiver Requirements
Waiver procedures and requirements can vary by county. Here’s a breakdown for Clark and Washoe Counties in Nevada:
Clark County
In Clark County, repairs must be performed by a 2G Licensed Authorized Station to be eligible for a waiver. When applying for a waiver, you must provide receipts from a 2G Licensed Authorized Station showing that a minimum of $450 has been spent. This expenditure must be on emission-related parts (excluding catalytic converters, fuel inlet restrictors, or air injection systems) or labor (excluding emission testing itself), directly related to the emission deficiency.

Repairs conducted at a non-authorized station in Clark County will not qualify your vehicle for a waiver, regardless of the amount spent. You can verify authorized stations through the Business License Verification resource.
Smog Free Clark County Voucher Program: Residents of Clark County with older vehicles (1968-1999) may benefit from the Smog Free Clark County Voucher program. This program, offered by the Clark County Division of Air Quality, can provide up to $975 towards emission-related repairs for eligible vehicles, subject to owner income restrictions. More details can be found at SmogFreeClarkCounty.com.
Washoe County
For Washoe County, waiver repairs can be carried out by a 2G Licensed Authorized Station or even by the vehicle owner. However, similar to Clark County, repairs done at a non-2G garage (if not by the owner) do not qualify for a waiver. A list of authorized stations is available via Business License Verification.
If repairs are done at a 2G station, the waiver application should include receipts from the station indicating at least $200 was spent on qualifying parts (excluding catalytic converters, fuel inlet restrictors, or air injection systems) or relevant labor costs (excluding emission testing).
If the vehicle owner undertakes the repairs, the waiver application must include receipts or proof of purchase for at least $200 spent on qualifying parts (excluding catalytic converters, fuel inlet restrictors or air injection system). These parts must have been purchased within 14 days after the initial emission test failure.
Requesting a Waiver After Failed Repairs
If your vehicle fails the emission test even after repairs, and you have met the financial requirements and repair guidelines for your county, you can formally request a waiver. To do this, bring your vehicle, both the initial and post-repair failed emission test certificates, and all repair receipts to a DMV Emission Lab. A DMV Emission specialist will review your documentation and vehicle to determine waiver eligibility.
By understanding these requirements, vehicle owners can navigate the process of emission testing and waivers effectively, ensuring their vehicles meet the necessary standards for legal operation and registration renewal.
