Last night, we asked you to take action to oppose a mandatory helmet law introduced in the Maryland House of Delegates’ Committee on Environmental Matters. In response, some of you asked for additional information on the “debatable” effects on bicyclists’ safety and the negative impacts on cycling that a mandatory helmet law would have. We vocally and overwhelmingly approve of helmets here at WABA. All of our staff and volunteers wear them, we require participants to wear them at all WABA events, and we teach how to wear them properly in all WABA education classes. Helmets provide an important last line of defense in the safety equation during a crash. When everything else has gone wrong, helmets have saved many bicyclists from more serious injuries or even death. We don’t get on our bikes without our helmets and we strongly encourage every cyclist out there to wear one. However, mandatory helmet laws requiring all bicyclists to wear helmets are not effective at increasing helmet usage without significantly affecting ridership. There are many studies that show helmet usage increases when laws are passed—but critically, not without a negative effect on overall bicycle ridership. In Australia, ridership dropped 37.5 percent between 1985 and 2011 after such a law was passed. During the same time, population growth was three times higher than the growth of cycling, meaning following the passage of a mandatory helmet law, there was a net decrease in bicycling. These laws negatively impact bicycle ridership by throwing up one more barrier (financially and behaviorally) to bike riding. Therefore, a potential bicyclist will be driven to choose another mode of transportation. Additionally, a recent New York Times article quoted Piet de Jong, a professor in the department of applied finance and actuarial studies at Macquarie University in Sydney: “Pushing helmets really kills cycling and bike-sharing in particular because it promotes a sense of danger that just isn’t justified—in fact, cycling has many health benefits.” Jong has studied the public health impacts of bicycling and has concluded that the positive health benefits outweigh risks of helmetless riding 20 to 1. In a country in the midst of an obesity epidemic, encouraging a few miles of bicycling everyday could lead to a considerable reduction in overall healthcare costs. And as jurisdictions like Montgomery County consider bikesharing programs, it’s important that those programs are accessible. Mandatory helmet laws in Maryland could potentially kill the momentum for bikesharing, as the law would promote a sense of danger for cycling, ignoring the obvious overall health benefits. And finally, these laws are merely an easy “fix” for legislators that distract from larger safety issues—such as the lack of safe, separate and comfortable places to ride. Adults and kids need safe spaces to ride on our roads that are separate from cars. We at WABA believe there are better legislative ways to keep bicyclists safe, such as better and more targeted enforcement of current traffic laws (especially distracted driving), increased bicyclist education, and, most importantly, the construction of separated bicycling facilities. Helmets are an important part of keeping bicyclists safe and WABA enthusiastically supports their promotion and use, but mandatory helmet laws do more harm than good. The Maryland House of Delegates is considering removing the “under 16” age requirement of its current mandatory helmet law in HB 339 to require all bicycle riders to wear a helmet. Please take a minute and contact the members of the Committee on Environmental Matters and ask them to oppose HB 339.
