How Helmet Use Affects Your Case

#

Contributory Negligence
In some states, not wearing a helmet can reduce your compensation if you suffered head injuries. The defense may argue you contributed to your own injuries.

#

Comparative Fault
Many states use comparative negligence, where your compensation may be reduced by your percentage of fault. Not wearing a helmet could be considered partial fault for head injuries.

#

Best Practice
Regardless of the law, wearing a DOT-approved helmet significantly reduces your risk of fatal head injury and strengthens your legal position if you're in an accident.
