California Assembly Bill 712: A Move to Exempt Classic Cars from Smog Checks
California is considering a significant legislative change concerning classic vehicles with the introduction of Assembly Bill 712 (AB 712), sponsored by Senator Shannon Grove (R-Bakersfield). This bill proposes eliminating the requirement for smog checks for specific vintage cars that are at least 35 years old.
Current Smog Check Regulations
Under current California law, collector motor vehicles—classics that are primarily used for exhibitions, parades, and similar events—are already exempt from certain aspects of smog testing. However, these vehicles must still undergo testing every two years or when ownership is transferred. AB 712 aims to completely remove these testing requirements for qualifying vehicles.
Support from Auto Enthusiasts
The bill has received notable backing from automotive public figure and talk show host Jay Leno. Leno is set to participate in a supportive event at the California state capitol, coinciding with the scheduled hearing for AB 712. His involvement underscores the enthusiasm for preserving historic automobiles and their significance in Californian culture.
Legislative Support and Opposition
AB 712 has garnered bipartisan support, including from Senate Transportation Committee Chair Dave Cortese (D-Silicon Valley), who serves as a co-author of the bill. Proponents argue that exempting these vehicles from smog checks would protect California’s rich automotive history, as these cars are rarely driven and are meticulously maintained.
Environmental Concerns
Despite the bill’s support, it faces opposition from the California Air Pollution Control Officers Association. The organization raises alarms about environmental impacts, noting that older cars can produce far greater emissions compared to modern vehicles. According to their analysis:
- A new passenger car from 2025 emits significantly lower nitrogen oxide (NOx) levels compared to a 1982 model.
- Even when compliant with smog regulations, a 1982 vehicle can emit 123 times the NOx of a 2025 car if driven 3,000 miles per year. This is comparable to a modern vehicle being driven over 369,000 miles in the same period.
As the conversation around AB 712 unfolds, stakeholders will continue to engage in discussions weighing the cultural value of classic cars against their environmental repercussions.
Conclusion
California’s legislative process will determine the future of smog checks for classic vehicles as AB 712 progresses. With key figures like Jay Leno championing the cause, the outcome may significantly influence the preservation of automotive heritage in the state.
