The Network recently received a question from a health official who asked if the Network could refer her to resources on statewide bicycle laws. The official was specifically interested in information on how laws vary across states as well as data on the effect of such laws on injury rates.

The Network referred the official to several resources on both the implementation of statewide bicycle laws nationally and the effect of these laws on rates of helmet use and injury.

Resources provided to the official included:

• A national map and a table of statewide bicycle helmet laws from the Insurance Institute of Highway Safety.
• A table listing the application of bicycle helmet laws in every state that has implemented such a law from the Insurance Institute of Highway Safety.
• An article published in the Journal of the American Medical Association entitled, “Effectiveness of Bicycle Safety Helmets in Preventing Head Injuries: A Case-Control Study” (subscription required).
• An article published in the Canadian Medical Association Journal entitled, “Nonuse of Bicycle Helmets and the Risk of Fatal Head Injury: A Proportional Mortality, Case-Control Study.”
