Which of the following is true about securing the helmet strap?

• A. It should be left unfastened when not in use.
• B. It should fasten securely.
• C. It should be tied to the rider's leg.
• D. It should be fastened loosely.

Answer: (B)

A helmet strap must be fastened securely to keep the helmet on your head in a crash or during hard riding. When the strap is snug under the chin and fastened, the helmet won’t slide off or move around if you lean, brake suddenly, or fall. This secure fit is what makes the helmet effective at protecting your head, since a loose or unfastened helmet can come off or shift, reducing protection when it’s most needed. Leaving it unfastened makes it easy for the helmet to come off; tying it to your leg won’t secure the helmet to your head and can cause entanglement or injury; fastening it loosely won’t stop the helmet from moving or coming off.
