What is the maximum age of a vehicle that can be exempt from the Smog Check in California?

In California, a vehicle that is 1975 model year or older is exempt from the Smog Check requirement. This means that if a vehicle was manufactured in or before 1975, it does not need to undergo the emissions testing that newer vehicles are subject to. The exemption is primarily aimed at older vehicles that typically have less emission control technology and are often considered to be collector's items rather than daily drivers.

The rationale behind this rule is to alleviate the regulatory burden on owners of very old vehicles and to recognize that these older cars generally have much lower usage rates on public roads compared to newer vehicles. This allows them to remain on the road while reducing the impact of emissions testing on owners of classic cars.

Other options do not align with California’s regulations regarding smog check exemptions. Vehicles newer than the current model year are often still under warranty and require testing, while the model year 2000 and earlier does not qualify for the same exemption as vehicles from 1975 model year and older. Additionally, vehicles from the 1980 model year or older fall under similar regulations but do not benefit from the exemption as applied to the 1975 model year cutoff.
