A proper head and neck restraint will greatly improve your chances of escaping uninjured in the event of a crash. The majority of major injuries in racing accidents are due to basal cranial fractures, or whiplash. Head and neck restrains are a great way to protect yourself against these types of injuries, and they're the cheapest insurance policy you can buy. Certain head and neck restrains limit the movement of your helmet relative to your body, protecting your from stretching your neck too far in the event of a crash. If you want to feel comfortable and confident while driving, a head and neck restraint is a must-have.

HANS devices, one of leading brands of head and neck restraints, weren't widely used in Formula One until 1994, following the deaths of drivers Roland Ratzenberger and Ayrton Senna.
