TRAFFIC OPERATIONS: Rectangular Rapid Flashing Beacons (RRFB)
What is it?
An RRFB is a pedestrian-actuated warning device used at uncontrolled crosswalks to warn motorists of pedestrians or bicyclists waiting to use, or that are already using, the crossing. It has flashing yellow lights that are highly visible to motorists that may be approaching the crossing.
Why are RRFBs used?
Although state law requires people to yield at any marked or unmarked crosswalk, the RRFB increases driver awareness of users that may be crossing the roadway. The lights and signs alert people traveling along the road that someone is using the crosswalk.
