How Helmet Use Affects Your Case

#

In States Without Requirements Generally, helmet use cannot be used to reduce your damages. The driver's negligence caused your accident.

#

In States With Requirements If you violated the helmet law, insurance companies may argue contributory negligence.

#

Practical Reality Even in no-requirement states, insurance companies often try to blame unhelmeted cyclists. An experienced attorney can counter these arguments.

Our Recommendation Wear a helmet regardless of legal requirements. It protects your brain and strengthens your legal position.
