What does it mean when the phrase 'road blocked' is reported?

When the phrase 'road blocked' is reported, it indicates that all lanes of the roadway are obstructed to traffic. This means that vehicles cannot pass through in either direction due to some form of barrier or obstruction, which could be caused by accidents, road construction, or other incidents. This designation is crucial for dispatchers and drivers because it informs them that they will need to find alternative routes, as there is no possibility of travel on that specific route until the blockage is cleared. Understanding this terminology helps ensure that traffic flows smoothly and safely, avoiding congestion and potential hazards that could arise from trying to navigate through a blocked road.
