What is the future of the RRFB?

What has happened?

On December 21, 2017, the Federal Highway Administration (FHWA) terminated the Interim Approval for Optional Use of Rectangular Rapid Flashing Beacons (IA-11). The FHWA’s position, as stated in their termination announcement, is that the RRFB is subject to current and pending patents and, as such, may not be included in the MUTCD or any interim approval. See the full text here.

What are your options?

  • RRFB installation after Dec. 21, 2017, are not in MUTCD-compliance. We recommend you contact your local State DOT to see if you are in compliance for projects that are in progress.
  • Installed RRFBs may remain in place until the end of their life cycle. Only then will a retro-fit or replacement be required. Coral Sales Company will continue to sell approved RRFBs systems and support all our current installations.
  • Coral Sales offers retro fit and new 8" or 12" round beacon options. Go to our Pedestrian Activated Beacon section here to see more.
