In California, most gasoline-powered, hybrid, and alternative-fuel vehicles from model year 1976 and newer are required to pass a Smog Check every two years, when changing ownership, or when registering for the first time in the state. Diesel vehicles from model year 1998 and newer under 14,000 pounds also require testing. Motorcycles and electric vehicles are exempt. Los Angeles drivers can choose from a wide range of certified Smog Check stations, including Test-Only and STAR-certified facilities licensed by the Bureau of Automotive Repair (BAR).
STAR stations meet higher performance standards and are authorized to inspect vehicles directed by the DMV for specialized emissions testing. Your DMV registration renewal notice will indicate whether a STAR station is required. Be sure to bring the notice with you to ensure proper certification submission to the DMV.
Smog Check stations in Los Angeles serve all types of vehicles—from compact cars and SUVs to trucks, vans, and RVs. Many locations offer walk-in service with short wait times, and pricing often includes the required certificate. For vehicles that fail the initial inspection or are identified as gross polluters, certified retesting and repair options are available to get you back on the road.
If your vehicle fails its Smog Check, you may qualify for financial assistance through California’s Consumer Assistance Program (CAP), which provides up to $500 for eligible repairs or up to $1,000 for retiring high-polluting vehicles.
