An obstruction on a road is anything that prevents or slows down movement, making it difficult for vehicles or pedestrians to pass.

Obstructions can create hazards, causing drivers to slow down, stop, or change direction. It is important to clear these blockages to maintain safe and smooth traffic flow on roads.
