Shoulder Drop Off (plaque) Sign - W8-17P

This critical road safety sign alerts drivers to potentially dangerous shoulder conditions where sudden elevation changes pose a significant risk. Engineered to meet both DOT and MUTCD state and federal guidelines, the sign features high-intensity reflective sheeting mounted on durable aluminum with radius corners and 3/8" prepunched mounting holes. Specifically designed for locations where an unprotected shoulder drop-off adjacent to the travel lane exceeds 3 inches in depth over a continuous roadway length, this supplemental plaque (W8-17P) provides essential warning information to motorists. When mounted below the standard shoulder drop-off warning sign (W8-17), it enhances driver awareness and helps prevent potential vehicle accidents.
