600x400mm Aluminium Obstruction Marker | Roadworks

The Central Obstruction Marker is a high-visibility warning sign used to alert drivers to hazards positioned in the middle of a thoroughfare. These road signs are essential for roadworks, highway maintenance, and temporary traffic diversions where an object or structure creates a physical blockage that requires motorists to merge or deviate from their path.

By using Class 1 reflective sheeting, the marker ensures that obstructions remain visible during night operations or in poor weather conditions. This reduces the risk of vehicle collisions by providing early warning to drivers, giving them sufficient time to adjust their speed and steering. The rigid construction allows for secure mounting on temporary barriers or permanent posts, ensuring the sign stays upright and legible despite wind or passing traffic turbulence. Site supervisors and traffic controllers benefit from a marker that provides clear, consistent communication to the public without requiring constant repositioning.

Constructed from aluminium, this marker measures 600x400mm to provide a clear visual profile. The combination of durable metal and reflective surfacing makes it suitable for high-traffic zones and outdoor environments exposed to the elements.
