A multi-year study found that when motorcyclists were involved in accidents, about 17% of riders also incurred a brain injury. That means, perhaps surprisingly, that nearly 83% of the accidents caused serious injury only to other areas of the body.
The question many people have is, do motorcycle helmets significantly reduce the chance for brain injury? The multi-year study found that of those riders wearing a helmet, 12% experienced a head injury. Of those not wearing a helmet, 20% experienced a head injury – so the answer, in general, appears to be yes.
