Where:
On any road where part or all of the carriageway is temporarily closed.
These barricades are commonly found at construction sites, roadworks, accident sites, or areas where maintenance or emergency operations are being carried out.
They may include a boom arm, cones, or other temporary physical barriers to prevent vehicle access.

Purpose:
To warn drivers that the road ahead is temporarily inaccessible and that traffic cannot continue through the barricaded section.
The barricade ensures the safety of both motorists and workers by clearly indicating that entry is prohibited.
It also signals that drivers need to follow alternative routes or detours to reach their destination.

Action:
Reduce your speed as you approach the barricade and do not attempt to bypass or move it.
Pay close attention to additional regulatory or directional signs indicating an alternative route or detour.
Follow any instructions provided by traffic controllers, flag persons, or automated signals.
Exercise caution, as temporary road conditions may include uneven surfaces, construction equipment, or personnel working close to the traffic lanes.
Always proceed carefully and stay alert for changes in traffic patterns around the barricaded
