Rumble Strips

A cyclist’s helpful friend or worst enemy.

"Rumble strips are the direct cause of me being hit by a car in New Mexico. But it’s not really the rumble strips that are the issue — it’s the lack of rideable space to the right of the strips."
—Bruce Gordon, Halfmoon Bay, British Columbia

rumble strip 1
With minimal or no rideable shoulder, rumble strips force cyclists into the travel lane, which is especially dangerous on high-speed or high-traffic roads.

Hitting a rumble strip can also cause cyclists to lose control.
rumble strip 3
The increased potential of being hit by a motorist is an unacceptable risk.

Rumble strips continue to be systematically installed on more bike routes than ever without following bicycle safety standards.
Here’s how we’re working to change this.
Transportation agencies decide the when, where, what, and how of rumble strips, so it’s our job to share bicycle safety practices with them and hold them accountable.
Bike-Friendly Design
1. Bike-Friendly Design
We advocate for bicycle safety best practices so agencies can improve state rumble strip policies.
Expert Oversight
2. Expert Oversight
Bicycle experts should have oversight on rumble strip projects to ensure best practices are followed throughout the process.
Quality Control
3. Quality Control
Agencies should use a review process to make sure rumble strips are implemented correctly the first time. And to fix them if they’re not.
