"Road Closed Ahead" traffic warning sign alerts drivers to changing road conditions

Made of high-intensity and highly reflective prismatic sheeting, this sign is three times brighter than those made with engineer-grade reflective sheeting. This construction technique makes it ideal for roads, highways, parking lots—anywhere traffic control is needed. This sign is visible at night up to 1,000' and designed to last for years—even when exposed to the harshest weather conditions. This sign is an ideal choice for traffic alerts to protect your workers and meet federal and state compliance codes. Measures 30"H x 30"W.
