Class 1 Aluminium Obstruction Marker | Road Hazards

Traffic controllers and road maintenance crews use this obstruction marker to alert motorists to fixed hazards. It is a specialised addition to a site's road signs inventory, designed to sit at the edge of the carriageway where physical barriers or roadwork equipment may encroach on the driving lane. This ensures that drivers are warned of a potential collision point before they reach the obstruction.

By providing a high-visibility warning, this marker reduces the risk of vehicle impacts in low-visibility conditions or high-traffic zones. The large surface area allows the warning to be seen from a distance, giving drivers ample time to adjust their speed or lane position. Because it is constructed from aluminium, it withstands the harsh environmental exposure typical of roadside installations without warping or corroding, meaning fewer replacements are needed during long-term projects. Site supervisors benefit from a reliable marker that stays upright and visible throughout the duration of the works.

This marker is built from Class 1 aluminium and measures 1800x450mm. These specific dimensions and material properties make it suitable for permanent or semi-permanent installations on high-speed rural roads or urban construction zones.
