Ramp Metered When Flashing
The ramp-meter signal ahead is active when the beacon is flashing.
Tells drivers entering a freeway ramp that the metering signal is in operation only while the attached beacon flashes. When the beacon is dark, proceed normally; when it flashes, expect to stop at the meter and merge one vehicle at a time.
