The Office of Safety has revised two technical advisories on rumble strips issued earlier this year, T 5040.39 Shoulder and Edge Line Rumble Strips and T 5040.40 Center Line Rumble Strips. The revisions clarify several key concepts, including:
The recommendations continue to provide agencies information to make informed decisions about the design and installation of rumble strips based on documented research, while allowing flexibility in application appropriate to the specific project and location.
The revised Technical Advisories will replace the current version posted on our web site. Also, the Office of Safety will shortly be updating the rumble strip web site, including the frequently asked questions. Please distribute the revised advisories to your state and local agencies and other industry partners. If you have any questions, you may contact Cathy Satterfield at 708-283-3552 or firstname.lastname@example.org.
