Whether helmets prevent death in a motorcycle crash is an interesting question and one that, statistically speaking, is answered in the negative.
While numerous states have mandatory helmet laws and some do not, the whole argument about wearing or not wearing a noggin protector mostly boils down to whether they prevent death. The interesting answer is not likely. The helmets protect the skull from serious injury, but often the cause of death in a motorcycle versus car accident is due to other reasons. In fact, existing federal data shows that most bikers who die would have been killed even if they had been wearing helmets.
On the other side of the coin, if a biker lives to tell his Atlanta personal injury lawyer about the crash, you can assume they have sustained some fairly serious injuries that would lay them up long-term or permanently. This brings us back to the argument about wearing helmets to prevent death. In reality, the risk a rider takes, whether they wear a helmet or not, is crashing. If you get into a head-on collision while doing 80 mph, your head is not the only part of your body that will take a beating.
