Only 19 States in the USA have a universal helmet law [1] – requiring ALL motorcyclists to wear a helmet. 28 States have partial laws, requiring helmet use up to a certain age, while 3 States have no laws requiring a helmet to be worn.

The map below shows the number of lives saved by helmet use per 100K registered motorcyclists for each state [2]. There is a clear correlation between the number of lives saved and the state’s helmet laws.
