The primary entities involved in road safety include the National Highway Traffic Safety Administration (NHTSA), which sets safety standards for vehicles and roadways; the Federal Highway Administration (FHWA), responsible for highway planning, design, and maintenance; the Insurance Institute for Highway Safety (IIHS), an independent organization that tests and evaluates vehicle safety; the National Transportation Safety Board (NTSB), which investigates transportation accidents to determine causes and make safety recommendations; and law enforcement agencies, which enforce traffic laws, respond to crashes, and conduct safety campaigns to deter dangerous driving behaviors.
