A Smog Check is an inspection program designed to measure the levels of pollutants and emissions produced by a vehicle's engine. It ensures that cars and trucks meet the emissions standards set by the Environmental Protection Agency (EPA) (epa.gov) and state regulations. The goal is to reduce air pollution caused by excessive emissions from motor vehicles.
Smog checks are typically required in states with dense populations and higher levels of vehicle-related pollution, such as California. These inspections help ensure that vehicles are not releasing harmful pollutants like carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) into the atmosphere.
During a smog check, certified technicians inspect the vehicle's exhaust system, engine diagnostics, and emissions control components. They also use advanced diagnostic equipment to measure emissions output and verify compliance with environmental standards.
How Much Does a Smog Check Cost?
The cost of a smog check can vary depending on several factors, including the type of vehicle, its age, and the location of the inspection station. On average:
Passenger Vehicles: $40–$70
Trucks, SUVs, and RVs: $50–$90
Older Vehicles (1995 or earlier): $80–$120 (due to additional testing requirements)
Prices may also differ based on whether the vehicle passes or fails the inspection. Some states offer financial assistance programs for low-income vehicle owners who need smog repairs to meet emission standards.
It’s essential to check local regulations and pricing before scheduling an appointment.

STAR Certified Smog Stations
In California, STAR Certified Smog Stations are designated by the Bureau of Automotive Repair (BAR) (bar.ca.gov) for meeting higher performance standards. These stations are authorized to perform both regular smog inspections and STAR-directed inspections, which are required for certain vehicles identified by the DMV. Vehicles may be flagged for a STAR inspection based on their make, model, year, or previous smog check history. Choosing a STAR-certified station ensures a high standard of testing accuracy and compliance with state requirements.
Why a Smog Check is Required for DMV Renewal, Title Transfer, and Out-of-State Vehicles
In many states, including California, a smog check is required every two years as part of the vehicle registration renewal process. The DMV will not process your renewal without proof of a passing smog inspection. Newer vehicles may be exempt for the first six years, but annual requirements vary by state.
When transferring a vehicle title to a new owner, the DMV often requires a valid smog certification. This ensures that the vehicle is environmentally compliant before the transfer is completed. Buyers should verify the smog check status before finalizing the purchase.
If you’re bringing a vehicle into a state like California from another state, it must pass a smog check before it can be registered locally. Even if the car was recently inspected in its previous state, local emissions standards may differ, requiring a fresh inspection.
How to Prepare for a Smog Check
Ensure Proper Vehicle Maintenance: Regular tune-ups, oil changes, and air filter replacements can improve your chances of passing.
Check Warning Lights: Ensure that the check engine light is off.
Drive Before the Test: Drive the vehicle for at least 20 minutes before the inspection to warm up the engine.
Use Quality Fuel: Fill up with high-quality gasoline.
Fix Known Issues: Address any mechanical problems in advance.
