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.

How to use:

MOTORISTS AND BICYCLISTS IN THE TRAVEL LANE:

  • Begin yielding when approaching an activated RRFB.
  • Do not pass another vehicle that has stopped or is slowing down at a crosswalk.
  • Come to a complete stop before reaching the crosswalk.
  • Remain stopped for pedestrians or bicyclists that are within the crosswalk until they are fully out of the crosswalk.
  • After the crosswalk is clear, resume travel.

PEDESTRIANS AND BICYCLISTS USING THE CROSSWALK:

  • Press the button on the RRFB to activate the flashing lights.
  • Check to see that motorists are yielding before proceeding.
  • After ensuring vehicles have yielded, cross the street.
  • Bicyclists should enter the crosswalk in a manner consistent with the safe use of the crosswalk by a pedestrian.
