What are they?
 The basic marked crosswalk installation (which consists of two painted lines across the roadway and four ground-mounted pedestrian crosswalk signs - two signs for each direction of travel) may be supplemented by overhead illuminated pedestrian crosswalk (RA-5) signs. Two RA-5 signs are required for each crosswalk and are positioned over the centre of the approach lane(s) with the pedestrian symbol oriented to the center of the roadway. As well as helping to indicate the location of the crosswalk at night, the illuminated RA-5 sign provides down-lighting over the crosswalk area.
The RA-5 signs may be supplemented by pedestrian actuated flashing amber lights. Each sign has two flashing light units, one facing in each direction, flashing alternately.
Where are they used?
RA-5 overhead illuminated crosswalk signs may be installed at existing marked crosswalk locations when there is a demonstrated need for nighttime illumination of the crosswalk area which is not provided by existing street lights. RA-5 signs may also be considered for use when vehicular approach speeds are high, when visibility of the crosswalk is limited and/or there is a history of pedestrian related accidents. RA-5 signs with pedestrian actuated flashing amber lights are intended for use on multi lane roadways.
