My Registration Renewal Notice says “Smog Certification Required at a STAR Station”. What does it mean?
STAR stations are smog check stations that meet higher performance standards established by the Bureau of Automotive Repair (BAR). In order to comply with state law, BAR directs a portion of the vehicles registered in Enhanced Smog Check Areas to STAR stations. Enhanced Areas are those parts of the state with "serious", "severe", or "extreme" ozone pollution problems. Directed Vehicles must have their smog check done at one of these stations.
If my Registration Renewal Notice says "Smog Certification Required” (not Directed Vehicles), can I have smog check done at a STAR Test-Only Station?
Yes, you can. STAR Test-Only facilities are licensed smog check stations that are allowed to perform any type of smog check for hybrid, gas- or diesel-powered vehicles.
What is an "EVAP" Test?
The Low-Pressure Fuel Evaporative Test (LPFET) checks for leaks in the fuel tank or associated evaporative system hoses and devices. As of December 2007, the state of California requires this test during a smog check for 1976 to 1995 model year vehicles, including all pre-OBDII vehicles.
Exemptions:
- Vehicles not originally equipped, and not required by state or federal law to be equipped, with a fuel evaporation control system;
- Vehicles with two or more fully operational fuel tanks;
- Vehicles powered exclusively by compressed natural gas (CNG), liquid natural gas (LNG) or liquid petroleum gas( LPG);
- Vehicles for which there are no filler neck adapters;
- Vehicles in their original factory configuration, with a fuel evaporative canister and fuel vapor hoses that are not accessible or would require the partial dismantling of the vehicle in order to gain access to them for testing.
