The purpose of the RAMP SPEED KM/H sign is to indicate the safe speed of travel on the ramp of an interchange or channelization leg. WA-32 is used on roads with posted limits of 60 km/h or less, WA-132, 70 km/h & WA-1132 for speeds of 90 km/h or over. This version includes the KM/H text on the same sign.
