Opponents of mandatory helmet laws for motorcyclists claim that such laws are intrusions on individual freedom. These individuals believe that they have a right to ride a motorcycle without the government telling them that they have to wear a helmet. Proponents of these laws cite the reduced number of serious injuries and even deaths when helmets are worn as sufficient reasons to have such laws. Discuss this issue and pay specific attention to the externalities which may result from motorcyclists riding with or without helmets.
