Great news for pedestrian and traffic safety. The Rectangular Rapid Flashing Beacon (RRFB) again has interim MUTCD approval!
In 2017 SA-SO Signs & Safety became aware that Rick Jones of Stop Experts had filed a patent infringement case on the flashing pattern of the RRFB. As a result many cities and towns put a halt to purchasing RRFBs. We also learned The Federal Highway Administration (FHWA), who deems traffic and safety devices as MUTCD compliant, revoked the RRFB's interim MUTCD approval.
In 2018, Carmanah Technologies Corporation, who is also a manufacturer of traffic and safety products, purchased the RRFB patent from Rick Jones. As a result, Carmanah “disclaimed the patents,” which allowed it to be put in the public domain. What this means is that now all traffic and safety companies are allowed to manufacture and distribute the RRFB without threat of lawsuit. RRFBs have been proven to increase pedestrian awareness and reduce injuries and deaths in communities throughout our country and nationwide.
Furthermore, in March, FHWA announced a new interim approval for the use of RRFBs. The new interim approval IA-21 replaced the original one issued to Rick Jones.
