Bicyclists are at a significant disadvantage on Washington State roadways when it comes to safety, primarily because the lack of protection they are provided compared to a person driving a motor vehicle. As a result of the increased vulnerability, the injuries to bicycle accident victims are often much more significant than to motorists.
Currently in Washington, there are no state laws requiring that bicyclists wear helmets while on state roadways. However, several counties and cities throughout the state have enacted laws that require helmet use, sometimes depending upon the rider’s age.
Below is a list of cities and counties in Washington State that have enacted some form of helmet law for bicyclists, along with the year that the law(s) were enacted and the age group(s) that are affected by it:
