Evaluation of the costs and benefits of motorcycle helmet laws.
A Muller
Since 1976, 28 states have repealed or significantly amendedtheir motorcycle helmet laws. The change in legislation wasnot based on an evaluation of the costs and benefits of suchlaws. This paper attempts such an assessment by comparing thecost of motorcycle helmets with the medical costs averted dueto helmet use using data primarily based on motorcycle crashesin Colorado, Oklahoma, and South Dakota. Nationwide, at least$61 million could be saved annually if all motorcyclists wereto use helmets. Helmet law repeals have been observed to leadto a 40 to 50 per cent point reduction in helmet use. The associatedadditional medical care costs substantially exceed cost savingsproduced by reduced helmet use. It is estimated that helmetlaw repeals may produce annually between $16 and 18 millionof unnecessary medical care expenditures. Several alternativesto increase motorcycle helmet use are briefly discussed. Itis concluded that helmet laws are effective in encouraging helmetuse among motorcyclists and will prevent unnecessary medicalexpenditures as well as unnecessary pain and suffering amonginjured motorcyclists.
