What should be done if a helmet moves when shaking your head?

If a helmet moves when shaking your head, it indicates that the helmet may not be properly fitted. Ensuring a helmet fits snugly is crucial for maximum protection as it helps to keep the helmet in place during an impact. A helmet that shifts or moves can decrease its protective capabilities, potentially leading to injury during a fall or collision.

Adjusting the helmet for a better fit involves tightening any adjustable straps or using padding to ensure that it fits securely without being overly tight. A correctly fitted helmet should feel snug around the head and stay in place during movement. This adjustment process is essential to enhance safety and ensure that the helmet functions as intended in protective situations.
