Which agency's standards must an ATV helmet meet?

The correct choice is that an ATV helmet must meet the standards set by the Department of Transportation (DOT). DOT helmets are specifically designed for motorized vehicle use and must adhere to rigorous safety standards that evaluate impact absorption, penetration resistance, and retention system effectiveness. These standards ensure the helmet provides adequate protection in the event of an accident or collision, which is essential for the safety of ATV riders.

While other agencies like the Consumer Product Safety Commission (CPSC) do set standards for consumer products, and the Environmental Protection Agency (EPA) is focused on environmental protection, their regulations do not specifically pertain to the safety standards for ATV helmets. The Federal Aviation Administration (FAA) is responsible for regulating civil aviation and does not relate to land vehicle safety standards. Therefore, the DOT is the recognized standard for ensuring that helmets meet the necessary safety requirements for ATV use.
