Rumble strips are raised or grooved patterns in the travel lane and/or shoulder that create noise and vibration. With the proper design and construction, rumble strips may provide some traffic calming benefit. As an example, shoulder rumble strips along the interstate may help prevent run-off-the road crashes. Due to the noise created by rumble strips, we do not recommend the use of rumble strips in residential land use areas to slow traffic. They do create a noise that may alert drivers, but also agitate the surrounding neighbors every time a vehicle crosses the device (even throughout the night). Rumble strips are more appropriate in a rural setting or well outside of a neighborhood setting.
