IFTA Decal laws in Colorado

The International Fuel Tax Agreement (IFTA) is a cooperative agreement among states and Canadian provinces that simplifies the reporting of fuel use by motor carriers operating in multiple jurisdictions. To operate legally under IFTA, qualified motor vehicles must be registered with a base jurisdiction, which then issues IFTA decals. These decals serve as proof that the vehicle is operating under the IFTA system and that the carrier is meeting its fuel tax obligations. In Colorado, as in other member jurisdictions, commercial vehicles that meet specific criteria for weight and number of axles, and that cross state lines, are generally required to participate in IFTA. Obtaining and properly displaying these decals is a fundamental aspect of compliance for eligible carriers. Failure to adhere to these requirements can result in administrative actions and potential operational disruptions.
