Feds reinstate use of rectangular rapid flashing beacons

The use of the beacons was terminated due to a patent issue associated with the device.

The Federal Highway Administration (FHWA) is once again allowing Rectangular Rapid Flash 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 due to patent issues. The reversed decision came about because Canadian company Carmanah Technologies Corporation purchased and disclaimed the RRFB patents. This ensures that cities throughout the nation can use the pedestrian safety devices.
