On the other hand, if you were wearing the helmet, statistics on the effectiveness of helmets could be introduced as evidence that you did not contribute to your injuries through negligence or carelessness. Information from the National Highway Traffic Safety Administration (NHTSA) states that a motorcyclist wearing a helmet lowers the risk of fatal injury by 37%.
Nevertheless, even if you failed to wear a helmet, if you were hit and the motorist caused the accident, he is likely to be at fault, and you may still have a good claim. If your injuries were other than to the head or brain, the helmet is not relevant in assessing damages. After all, how would a helmet protect you against a broken leg? Opposing counsel may argue that the type of serious injuries you suffered could have been prevented by a helmet. The statistics on motorcycle helmet use and injury or death actually play in their favor. According to the NHTSA, motorcycle helmets saved 1,658 lives in 2006. In fact, the NHTSA says that if all motorcyclists had worn helmets, 752 more lives would have been saved.

Sometimes the police respond to the scene of an accident and may issue a traffic ticket to a party perceived as having done something wrong. You should get a copy of any written police accident report or other investigation that was done. Some states may have laws that prevent anyone from filing a lawsuit if it stems from something they have done which violates a law. (For instance if someone broke into your home and got bitten by your dog, the injured thieves probably wouldnt get too far in court). However, in practice, its the total circumstances that determine the outcome.
