Why is it crucial to secure the helmet's straps properly?

Securing the helmet's straps properly is essential to ensure that the helmet remains in place during an accident. A helmet is designed to absorb impact and protect the head from injury, but its effectiveness can be significantly compromised if it shifts or comes off upon impact. Properly adjusted straps ensure a snug fit, allowing the helmet to stay securely positioned on the head. This minimizes the risk of the helmet rotating or dislodging, which could expose the wearer to severe head injuries. The straps are a critical component of the helmet's safety features, and failure to secure them properly can negate the protection that the helmet provides in the event of a fall or collision.

Other options may address aspects unrelated to helmet safety or practicality, such as aesthetics or concerns like air resistance and noise, which are not primary considerations when it comes to the protective function of a helmet.
