When is it not permissible to pass a vehicle on the left?

Passing a vehicle on the left is prohibited at certain locations for safety reasons. Situations such as intersections, hills, or curves are particularly hazardous because visibility can be limited, and there can be unexpected obstacles or oncoming traffic that drivers cannot see in time. At intersections, vehicles may be turning or coming from different directions, and on hills or curves, the driver cannot ascertain whether the road ahead is clear, increasing the risk of a collision.

These rules are designed to ensure that drivers can make safe decisions and maintain control of their vehicles, as passing under these conditions could lead to dangerous encounters with other vehicles or pedestrians. Therefore, it is understood that avoiding passing at these critical points helps to promote overall road safety.
