When Flashing School Zone Sign

Description

The When Flashing sign (MUTCD S4-4) mounts beneath a school speed limit sign with beacons to show drivers the reduced limit applies only while the lights are flashing. That makes your school zone easier to understand during arrival and dismissal, and easier to enforce. School districts and traffic engineers use this school zone when flashing sign to complete beacon-equipped assemblies.
