Safe accommodation of all road users can be considered when designing and applying rumble strips. Rumble strips are primarily a safety device for passenger vehicles. For other road users, particularly bicyclists, they may cause concerns. A part of the success in accommodating the variety of road users present on our roadways is the use of flexibility in the design and placement of rumble strips.

To fulfill their purpose, tires must drop into the rumble and cause enough vibration or noise inside the vehicle to get the driver's attention. There are opportunities to reduce the impacts of rumble strips on other road users by adjusting dimensions and location. This section explores information about how to accommodate all road users with effective rumble strip design and implementation. Coordination with local bicycling organizations is highly recommended when developing policies and projects.
