As reported in the Feb. 22 Daily, a young and gifted graduate student died tragically from injuries sustained from a bicycle accident.

Despite aggressive Public Health efforts, this remains a not infrequent occurrence both nationally and locally, as bicycle accidents remain a significant percent of all traffic fatalities in both the US (2.3%) and within CA (3.2%)

The particulars of this recent tragedy are consistent with reported statistics and thus underscore the importance of ongoing safety efforts.  As with most traffic accidents, young men are the most at risk.  In 2008, 87% of cyclists killed were male and those ages 25 and older continue to make up an increasing proportion of fatalities, 64% in 2008.

Mr. Wang was not wearing a helmet at the time of his accident. It is certain that this was a contributing factor in his death.  Data compiled and reported by the National Highway Traffic Safety Administration (NHTSA) note that helmets are 85-88% effective in mitigating head and brain injuries.  Thus it remains alarming that only 20-25% of all bicyclists wear bicycle helmets, despite the fact that nearly 70% of all fatal bicycle crashes involve head injuries.

California is one of 21 states and the District of Columbia that has created age specific bicycle helmet laws (passed in 1986, effective in 1987).  Unfortunately, these helmet laws do not apply to adults and so they continue to contribute disproportionately to the fatality statistics. In addition to helmets, the most effective measures are education efforts and prevention.  Stanford should be applauded in the numerous measures the community has undertaken to increase awareness and compliance.  Nonetheless, as the recent tragedy demonstrates, we must continue to be vigilant.

As we approach March, Brain Injury Awareness month, it is important to remind all motorists and cyclists of their joint responsibilities in keeping safe.  The National Highway Traffic Safety Administration (NHTSA) and the Stanford Bicycle Program remain valuable resources.  Cyclists, let’s not forget to wear a helmet every time you ride and follow the same rules as other roadway users.  You are not invincible.
