The California Smog Check Program was first introduced in 1984 with the aim of reducing air pollution in the state. It ensures that vehicles comply with both state and federal regulations by subjecting them to a biannual inspection and emissions test. This helps to ensure that vehicles meet the guidelines set by the state and contribute to cleaner air.
The Smog Check program has certain exemptions, such as gasoline vehicles that are less than 6 model years old (4 model years for a change of ownership) unless brought in from out of state. Additionally, gasoline vehicles from 1975 or earlier are also exempt. However, diesel vehicles weighing over 14,000 GVWR and manufactured in 1998 or later require a biannual smog inspection and have no 6-year exemption. It’s worth noting that motorcycles do not need a smog check before registration in California..
The Smog Inspection program has been implemented to reduce ground-level ozone and particulate matter, along with other pollutants like carbon monoxide, nitrogen oxides, non-methane organic compounds, and air toxins. To comply with California state regulations, vehicle owners, motorists, or drivers must have their vehicles undergo an emissions inspection and pass it. Therefore, it’s essential to ensure your vehicle is tested and in good condition before scheduling a smog check appointment.
