In order to legally drive in California, you need to have a smog check on all your vehicles that are older than 6 years once every two years, or every year if you own a high-polluting vehicle. But how do smog tests work? How is the vehicle inspection actually done?

Only licensed technicians are able to perform a vehicle inspection. They will need to attach some equipment to your vehicle to measure pollutants.

The smog test consists of three different testings – functional inspection, visual inspection, and emissions inspection. Functional and visual inspections will allow the technicians to measure pollutants that your car is releasing. These include oxygen (O2), hydrocarbons (HC), carbon dioxide (CO2), and carbon monoxide (CO). These are usually the most common pollutants measured. However, in some of the US most polluted urban areas, you may also have your vehicle checked for oxides of nitrogen (NOx).
