What are the requirements for vehicle emissions testing in Idaho?

In Idaho, vehicle emissions testing is primarily required in specific areas known as nonattainment or maintenance areas, where air quality standards are not met or are being managed to maintain compliance. Generally, emissions testing is mandated for gasoline-powered vehicles that are model year 1996 and newer, along with heavy-duty trucks that are model year 2001 and newer. The testing is conducted to ensure that vehicles meet the state's emissions standards and help improve air quality. Residents in areas that require emissions testing must have their vehicles tested every two years. The testing is performed at certified emissions testing locations throughout the state. The test typically checks for the presence of pollutants and ensures the proper functioning of the vehicle’s emissions control systems. Additionally, vehicles that are powered by diesel fuel or older gasoline vehicles might have different requirements. Additionally, certain vehicles, such as those that are registered as classic or antique, may be exempt from testing requirements. For more specific information regarding testing locations, hours of operation, and any exemptions that may apply, it is advisable to consult the current web page of the Idaho Division of Motor Vehicles.
