What vehicles are exempt from the Smog Check Program?

The exemption from the Smog Check Program primarily applies to electric vehicles, hybrids, and vehicles manufactured before 1976. Electric vehicles do not produce tailpipe emissions, which eliminates the need for them to undergo smog checks. Similarly, hybrids are designed to operate more efficiently and often produce lower emissions compared to traditional combustible engine vehicles. Additionally, vehicles manufactured before 1976 are generally considered to be classic or antique vehicles and have been exempted from undergoing regular smog checks due to their age and the fact that they usually do not operate under the same emissions standards as newer vehicles.

In contrast, other categories such as all trucks or luxury vehicles do not have blanket exemptions under the Smog Check Program. Heavy-duty vehicles also typically have different regulations and are subject to their own specific emissions testing requirements rather than being entirely exempt. Thus, the correct answer accurately reflects the specific criteria that qualify vehicles for exemption under the Smog Check Program.
