What Is a Smog Test and Why Is It Important?

A smog test (also called a smog check) is a mandatory inspection of your car’s emissions control system to ensure it meets environmental standards. These tests are regulated by the U.S. Environmental Protection Agency (EPA) and enforced by your state’s DMV or air resources board.

Smog tests:

• Help reduce harmful pollutants

• Ensure your engine runs efficiently

• They are required for vehicle registration in many states

• Can identify engine issues before they worsen

If your check engine light is on, your vehicle will likely fail the smog test, making it critical to address any issues before testing.

Types of Smog Test Stations: What’s the Difference?

Understanding where to go for your smog check matters:

Smog-Test-Only Stations:

• Authorized to perform inspections only

• Cannot provide emissions repairs or certification

Smog Test and Repair Stations (like Wastler Auto Service):

• Fully licensed to test, repair, and certify your vehicle

• One-stop solution if your car fails its initial test

• Ideal for both first-time smog checks and follow-up inspections

Whether you’re driving a sedan, truck, SUV, or hybrid, we’re fully equipped to handle your emissions testing and any necessary repairs.

Common Reasons Vehicles Fail Smog Tests

Failing a smog test can be frustrating, but understanding the causes helps you prevent it. These are the most common issues:

• Faulty oxygen sensors

• Malfunctioning EVAP system

• Dirty or damaged catalytic converter

• Worn spark plugs or misfires

• Fuel system problems
