What Are Utah Vehicle Inspection Requirements?

Colton Jones • April 22, 2025

Navigating Utah's vehicle inspection requirements can be confusing, especially with the changes implemented in recent years. For Salt Lake City residents and those in surrounding counties, understanding what inspections are still required and when they're needed is essential to avoid fines and ensure your vehicle remains legally registered. Let's break down Utah's current vehicle inspection requirements and what they mean for you.

Current Utah Vehicle Inspection Requirements

Utah's vehicle inspection requirements have evolved significantly over the past few years. Here's what you need to know about the current situation:

Safety Inspections

As of January 1, 2018, Utah no longer requires regular safety inspections for most passenger vehicles. This change came with the passing of SB 59, which eliminated the longstanding requirement for periodic safety inspections on personal vehicles.

However, there are important exceptions:

  • Commercial vehicles still require annual safety inspections
  • Vehicles with salvage titles being registered for the first time need a safety inspection
  • Out-of-state vehicles being registered in Utah for the first time need a safety inspection
  • School buses, taxis, and other transportation for hire still require inspections

Emissions Testing

While safety inspections have been largely eliminated, emissions testing remains required in several Utah counties:

  • Salt Lake County: Required for all gasoline and diesel vehicles
  • Davis County: Required for all gasoline and diesel vehicles
  • Weber County: Required for all gasoline and diesel vehicles
  • Utah County: Required for all gasoline and diesel vehicles
  • Cache County: Required for all gasoline vehicles 6 years and older (1996 and newer)

For most counties, gasoline-powered vehicles need testing every two years, while diesel vehicles typically require annual testing.

Emissions Testing Exceptions and Exemptions

Not all vehicles need emissions testing, even in counties where it's generally required:

  • New vehicles: In most counties, vehicles less than two model years old are exempt
  • Vintage vehicles: Models from 1967 or earlier are exempt
  • Electric vehicles: Fully electric vehicles don't require emissions testing
  • Motorcycles: In most counties, motorcycles are exempt
  • Farm vehicles: Agricultural-use vehicles may be exempt with proper registration
  • Diesel vehicles: In Cache County, diesel vehicles are currently exempt

When Emissions Tests Are Required in Salt Lake County

For Salt Lake County residents, emissions testing follows specific patterns:

  • Even-numbered model years: Tested in even-numbered years
  • Odd-numbered model years: Tested in odd-numbered years
  • New vehicles: Exempt for the first two model years
  • Diesel vehicles: Annual testing required regardless of model year

This alternating schedule helps distribute testing throughout the year and reduces wait times at testing facilities.

Where to Get Emissions Testing in Salt Lake City

Salt Lake County offers numerous certified emissions testing stations, including:

  • Independent testing stations
  • Many automotive repair shops (like Jones Complete Car Care)
  • Some quick lube facilities
  • Select gas stations with service bays

The test typically takes 15-20 minutes and costs between $20-$35 depending on the facility and vehicle type.

What Happens During an Emissions Test

The emissions testing process varies slightly depending on your vehicle's age and type:

For 1996 and newer vehicles:

  • A technician connects to your vehicle's OBD-II (On-Board Diagnostics) port
  • The system checks for proper operation of emissions equipment
  • It verifies no emissions-related trouble codes are present
  • The test confirms all emissions monitors have completed their self-checks

For older vehicles (pre-1996):

  • A tailpipe test may be performed to measure actual emissions
  • Inspectors check for tampering with emissions equipment
  • Visual inspection of emissions components is conducted

What If Your Vehicle Fails?

If your vehicle doesn't pass its emissions test:

  1. You'll receive a detailed report explaining why the vehicle failed
  2. You'll need to make necessary repairs to the emissions system
  3. After repairs, you can retest (many stations offer free retests if you return within a certain timeframe)
  4. If repair costs exceed the waiver threshold (currently $450 for most vehicles), you may qualify for a waiver after documenting repair attempts

Salt Lake County offers a repair assistance program for qualifying low-income residents who need help meeting emissions standards.

Registration Renewal Process with Emissions Testing

The process for renewing your registration with emissions testing works as follows:

  1. Get your emissions test before attempting to renew your registration
  2. Keep your emissions certificate (though most stations now report results electronically)
  3. Complete your registration renewal online, by mail, or in person
  4. Provide proof of insurance along with your renewal application
  5. Pay applicable fees for registration and renewal

Most emissions testing stations can provide you with a Vehicle Emissions Report on site, which can be helpful if there are any issues with electronic reporting.

Planning Ahead for Emissions Testing

To avoid registration delays, consider these tips:

  • Check your registration renewal notice for emissions testing requirements
  • Schedule your test at least 2-3 weeks before your registration expires
  • Have any check engine light issues addressed before testing
  • Ensure your vehicle has been driven regularly before the test
  • Make sure your battery is in good condition (disconnected batteries can reset emissions monitors)
