UPDATE: Feds Reinstate Use of Rectangular Rapid Flashing Beacons

A win for safety in Kirkland and cities across the nation

Kirkland, WA – The Federal Highway Administration (FHWA) is once again allowing Rectangular Rapid Flashing Beacons (RRFBs) to be installed and used in cities across the nation. This decision comes after an outcry from cities across the U.S., including Kirkland, and is a big win for safety in the City.

The FHWA had previously revoked the use of RRFBs because patented devices are not allowed for inclusion in the Manual on Uniform Traffic Control Devices, the document that governs which traffic control devices are allowed in the public right of way. 

The reversed decision came about because Canadian company Carmanah Technologies Corporation purchased and disclaimed the RRFB patents. This ensures that the City of Kirkland can continue to install Rectangular Rapid Flashing Beacons for the safety of our residents. 

For more information on the FHWA’s reversed decision to reinstate the RRFB as an option, please reference their March 20, 2018, Memorandum.
