As one of the world’s most populated cities, Los Angeles is no stranger to air pollution and smog. Regrettably, Southern California is known to have the highest level of smog in the nation.
In an effort to reduce environmental damage and comply with the Clean Air Act, registered vehicles must abide by smog inspection regulations. However, there are few exceptions to the rule. Vehicles that DO NOT require a smog certification include:
- Diesel-powered cars made before 1998
- Cars with a gross vehicle weight of 14,000 pounds
- Electric cars
- Natural gas powered vehicles over 14,000 pounds
- Gasoline-powered automobiles constructed before 1975
- Hybrid cars
- Classic cars
Classic cars built before 1975 are usually constructed with simple emission control systems that have exhaust gas recirculation valves and air pressure sensors. Though each car model is different, typically a classic car will not produce as much carbon pollution as a modern car. Alternatively, certain classic cars can produce other pollutants that can be worse than modern cars.
