Hazmat Placard laws in Colorado
In Colorado, the use of hazmat placards is governed by federal regulations adopted by reference, primarily the Hazardous Materials Regulations (HMR) issued by the Pipeline and Hazardous Materials Safety Administration (PHMSA) within the U.S. Department of Transportation (49 CFR Parts 100-185). Colorado Revised Statutes (C.R.S.) § 42-20-101 et seq. ("Hazardous Materials Transportation Act") outlines the state's framework for hazardous materials transportation, aligning with federal standards. This means that any vehicle transporting hazardous materials in Colorado must properly display the placards specified by 49 CFR Part 172, Subpart F, indicating the class of hazardous material being carried. Failure to display the correct placards can lead to significant fines and potential seizure of the vehicle or cargo. The Colorado State Patrol is the primary enforcement agency for hazardous materials transportation regulations. They conduct inspections to ensure compliance with placarding, shipping papers, and other safety requirements. The specific requirements for placarding depend on the type and quantity of hazardous material being transported. For example, certain materials require placards regardless of quantity (e.g., poisons by inhalation, explosives), while others have quantity thresholds that trigger placarding requirements (e.g., 1,001 pounds aggregate gross weight of hazardous materials, per 49 CFR 172.504(a)). Penalties for non-compliance with hazmat placarding regulations can be substantial. Under federal law, civil penalties for violations of the HMR can be up to $89,678 per violation, per day, with higher penalties for those that result in death, serious injury, or substantial property damage. Additionally, knowing violations can lead to criminal penalties including imprisonment. Colorado law, C.R.S. § 42-20-111, states that any person who violates any provision of the Hazardous Materials Transportation Act commits a misdemeanor and is subject to fines and potential imprisonment, with increasing penalties for subsequent offenses or those involving serious injury or death.
