St. Louis Bicycle Helmet Law

Missouri is home to the iconic Katy Trail and adventurous terrain for avid cyclists. Not only is it a bicycle-destination state, but it’s also a bike-friendly state for residents who choose to bike recreationally or to work and school. Despite being home to more than six cross-state bicycle routes, Missouri state law fails to address bicycle helmets with a universal helmet law. Instead, various municipalities in Missouri put their own bicycle helmet laws into place, making it necessary for cyclists to learn the laws in their local area or any location in which they plan to ride before hitting the road.

How Effective Is Bicycle Helmet Use?

According to research studies, bicycle helmets are effective in preventing serious head and upper to mid-level facial injuries. The study revealed a 69% effectiveness rate for bicycle vs. car accidents and 68% effectiveness for other types of bicycle accidents. The study showed that bicycle helmets are not effective in preventing injuries to the jaw and lower portion of the face. Despite the clear evidence of efficacy, Missouri state law does not address bicycle helmet use, choosing to leave the decisions to officials at the local level, including in St. Louis.

Does It Matter What Type of Bicycle Helmet I Wear in St. Louis?

Bicycle helmets in St. Louis must meet federal requirements when manufactured or distributed in the United States. Look for a helmet that meets standards by organizations such as CPSC, ASTM, or EN. Choose a helmet that fits comfortably while snug enough to remain in place. Choose a helmet that matches the type of riding you plan to do, whether it’s trail riding, road cycling, mountain biking, racing, or commuting. Use the foam siding pads to adjust the fit, and tighten the straps appropriately. Look for additional features such as ventilation and choose a style and color that you’ll feel comfortable wearing. Be sure to follow the manufacturer’s instructions for maintenance. For help with recovering compensation following an injury, the St. Louis personal injury lawyer from Miller & Hine is ready to help.
