Emissions and Your Collector Vehicle
What you need to know about state-by-state testing requirements.
Few factors have been more influential on collector car owners – and the American automotive landscape – than regulatory efforts to reduce air pollution. In 1970, Congress passed the first major Clean Air Act and set aggressive goals for reducing automotive emissions. U.S. automakers responded by detuning engines and adding primitive emissions control gear. By the mid-1970s, the era of big horsepower seemed all but over.
Due, in part, to subsequent efforts aimed at improving air quality, we’ve had to learn to live with unleaded gasoline, ethanol-blended fuels and the elimination of ZDDP in motor oil. Thankfully, car guys have proven a resilient bunch, and the car hobby has survived. The first “inspection and maintenance” programs began in 1983. These early inspections were intended to ensure that passenger vehicles in the country’s most polluted areas were factory equipped with functional emissions systems.
In 1990, Congress amended the Clean Air Act, giving the Environmental Protection Agency (EPA) broader authority to regulate tailpipe emissions and requiring that oxygenated gas be sold in the most polluted cities in the country. (Ethanol is currently the most widely used fuel oxygenate. For more information on ethanol and old cars, see Hagerty’s Spring 2009 and Fall 2009 issues.)
Congress also granted the EPA the authority to create National Ambient Air Quality Standards (NAAQS) to be met by every state. Ambient air quality is calculated by measuring amounts of six specific pollutants in outdoor air. NAAQS are the amounts of each pollutant that the EPA deems acceptable.
Each state is responsible for devising its own State Implementation Plan (SIP) for meeting the goals specified under NAAQS. While each state has a degree of autonomy in what it proposes in its SIP, the EPA ultimately must approve the plan. Needless to say, this has led to a wide degree of variation in the way that each state regulates the gases that come out of your car.
It has been proven that testing collectible cars provides little to no measurable benefit to the environment: There simply aren’t enough of them out there, they are usually well maintained and they are used relatively infrequently. Therefore, most states provide some type of exemption specific to older cars.
When considering the purchase of a new collector vehicle, it’s important to know how the regulations in your area will impact your ability to register, drive and enjoy it. If you are moving or purchasing a new vehicle and you have doubts about its emissions status, call the local department of motor vehicles or Hagerty Plus at 888-310-8020.
SHOULD YOU GET TESTED?
Here’s a breakdown of the emissions testing requirements in each state as they relate to collectible cars. It’s not meant to be comprehensive, but it does provide a general idea of how each state operates. Keep in mind that while U.S. regulations are made on the state level, they may only apply to certain counties within a state. Find this guide online at hagerty.com/emissions.
Testing is required for 1968 and newer vehicles owned by a person living in the Municipality of Anchorage, including Fort Richardson, Eklutna, Elmendorf AFB, Chugiak, Eagle River, Indian and Girdwood. Testing also is required for vehicles 1975 and newer and owned by a person who lives in the Fairbanks North Star Borough, including Eielson AFB, Fort Wainwright, North Pole and Salcha.
Pima and Maricopa Counties are subject to testing, but there is a broad exemption that includes many collectible vehicles.
Thirty-four counties in California require an emissions test every other year for vehicles 1976 and newer. Six counties require a test for vehicles 1976 and newer and registered in specific ZIP codes within those counties. Confused? Go to smogcheck. ca.gov/Applications/Ziparea/ ZipLookup.aspx and enter your ZIP code.

Vehicles 1995 and older are exempt from testing.
Vehicles registered with classic vehicle, classic rod or old-timer license plates and driven 2,500 miles or less per year are exempt from emissions testing.
All vehicles 20 years and older are exempt. Vehicles 1996 and older, but less than 20 years old, may receive a visual inspection during the state’s required safety inspection.

And in Canada…
Emissions testing isn’t required for passenger vehicles in most parts of Canada, but is required in British Columbia’s Lower Mainland region. However, vehicles with vintage plates (available for cars older than 30 years that meet a number of safety and usage criteria) are exempt. Southern Ontario also requires testing, but vehicles built in 1987 or earlier are exempt.
