​Your classic car and fuel emission testing: What you need to know

​Your classic car and fuel emission testing: What you need to know

0 Flares Filament.io 0 Flares ×

In 1970 the U.S. Congress passed the first Clean Air Act. This was a significant, aggressive step in setting goals for reducing auto emissions. It evoked an industry wide response as automakers added some of the first emissions control gear and detuned engines. It also initiated the end of the big horsepower era.

Big changes for passenger vehicles

It led to such changes as ethanol blended fuels and unleaded gasoline in vehicles and the end of motor oil that contained ZDDP. Early 1983 marked the first inspection and maintenance programs which were intended to target passenger vehicles in the most polluted areas of the country, ensuring that they were factory equipped with functional, appropriate emissions systems.

In 1990 the Clean Air Act was amended to provide the Environmental Protection Agency (EPA) with broader authority over vehicles and emissions. It required that oxygenated gas, such as ethanol, was sold in the U.S. cities that were the most polluted. It also regulated tailpipe emissions.

State Implementation Plan

While the NAAQA lays out the goals, it is up to each state to create its own State Implementation Plan, or SIP to meet those goals. Each state does have some degree of autonomy, but the plan must meet the approval of the EPA. This has resulted in a rather wide degree of variance on gas emissions from state to state.

Emissions and classic or collector cars

Studies have shown that doing emissions testing on classic or collector cars has very little impact on the environment. There is no measurable benefit to be noted simple because there are so very few compared to modern vehicles. Additionally, classic and collector cars are typically very well maintained and are not driven very often. This has prompted most states to provide certain exemptions that are specific to cars that fall into this category – older cars.

The best way to find out what the laws are in your state is to reach out to your local DMV. They have information on what cars are required to have emissions testing and which are exempt.
