Hazmat Placard laws in Arizona
The transportation of hazardous materials in Arizona is primarily governed by federal regulations, specifically the Hazardous Materials Regulations (HMR) found in 49 CFR Parts 100-185, which are enforced by the Pipeline and Hazardous Materials Safety Administration (PHMSA) and adopted by the Arizona Department of Transportation (ADOT). Carriers transporting hazardous materials that meet specific quantity and hazard class thresholds are required to display appropriate placards on their vehicles. These placards communicate the type of hazard present to emergency responders and the public. Failure to comply with these placarding requirements can result in significant penalties. Arizona Revised Statutes (A.R.S.) Title 28, Chapter 15, Article 1 and 2, broadly addresses the transportation of hazardous materials within the state through the adoption of federal regulations. A.R.S. §28-5201, for instance, mandates compliance with federal motor carrier regulations. The specific criteria for when placarding is required are detailed in 49 CFR Part 172, Subpart F, which outlines the hazard classes, quantity thresholds, and placard specifications. For example, specific placards are required for flammable liquids, corrosive materials, and explosives, among others, when transported in certain quantities. From a practical standpoint, the presence of a Hazmat Placard indicates that the driver and carrier are compliant with hazardous material transportation laws. It is not an 'accessory' in the typical sense but a mandatory safety device. Individuals or businesses transporting hazardous materials must ensure their vehicles are correctly placarded according to the materials being transported, their quantity, and the specific hazard classification.
