Florida Statute Section 316.2065(1)(d) requires that anyone under 16 wear a helmet while riding their bike. However, if someone 15 or under is not wearing a helmet and gets hit by a car and sufferers a head injury, the law does not prevent them from seeking compensation for their injuries. Florida law is a comparative negligence state.  This means that at trial, the attorney representing the negligent driver may be allowed to enter into evidence the fact of the non-use of a helmet, and the jury can apportion a percentage of blame to the injured bicyclist. Any award of money damages would then be reduced by that percentage.
