The National Marker Company sign with legend “ROAD CLOSED AHEAD” is primarily used to inform the drivers about the closed road ahead that can lead to congestion, thus it helps to avoid creating traffic and protect workers from being struck in work zones. The traffic control sign is made using premium and durable material that makes the sign suitable for extreme weather conditions. The legend is clearly visible and has bold text that ensures better visibility. It helps to protect workers such as emergency responders, utility, clean-up, and construction crews from accidents.
