State, tribal, and local governments typically provide for the safety of their residents and other persons and protection of resources within their jurisdictions. With respect to radioactive and hazardous materials, some State, tribal, and local governments enact legislation, execute cooperative agreements, designate alternate transportation routes, develop emergency response plans, perform emergency response, issue permits, conduct vehicle inspections, enforce traffic laws, and perform highway construction and maintenance. These activities must not conflict with Federal laws and regulations.
