Motorcycles are becoming an ever-more popular mode of transportation in the United States. However, the increase in the popularity of motorcycles inevitably leads to an increase in motorcycle accidents. Per vehicle mile traveled, motorcyclists were about 35 times more likely than passenger car occupants to die in a motor vehicle traffic crash and 8 times more likely to be injured. While motorcycles made up no more than 3% of all registered vehicles in the U.S., motorcyclists account for 15% of total traffic deaths. Unfortunately, when motorcyclists are involved in accidents with passenger vehicles, motorcycle riders and their passengers are also more likely to suffer serious injury and death as a result.
