Choose an example of a physical control.

• A. Wearing an approved Department of Transportation (DOT) helmet while riding a motorcycle.
• B. Conducting a monthly safety briefing.
• C. Installing a warning sign.
• D. Writing a safety policy document.

Answer: (A)

Physical controls are tangible devices or equipment that reduce your exposure to a hazard at the point of interaction. Wearing an approved DOT helmet is a direct, protective action you actively use during riding; it provides a physical barrier and absorbs impact, lowering the risk of head injury. The other options are not direct physical protections: a monthly safety briefing is an administrative activity that aims to influence behavior through information; a warning sign is primarily informational or an environmental cue rather than a piece of protective equipment you use, and a safety policy document sets rules but doesn’t physically alter the risk during the activity.
