February 23, Official Interpretation regarding the Flash Rate of Traffic Control Signals and Beacons On February 23, , the FHWA issued Official Interpretation 4 09 to clarify that the flash rate for traffic control signals and beacons is a single repetitive flash rate of approximately once per second, and that a combination of faster and slower flash rates that result in 50 to 60 flashes per minute is not compliant with Paragraph 1 of Section 4D.
Among these questions see Question 3 is how to handle situations involving agencies that prior to the December 21, termination date either had already purchased rectangular rapid flashing beacons RRFBs or had already included RRFBs in a contract, but had not yet installed the RRFBs in the field by that date.
