Description

The S4-4P sign, “WHEN FLASHING,” is a traffic sign that helps drivers understand which rules apply. This sign is typically paired with a reduced speed limit sign, but it only applies when the beacon lights on the sign are flashing. When the lights are on, it serves as a reminder for drivers to slow down, as conditions may be different, such as during school hours or when children are crossing the street. 

Customize your sign’s material and reflective sheeting grade to suit your needs.
