When a road is divided into three lanes and there's no other marking or direction, what is the center lane used for?

When a road is divided into three lanes and there are no specific markings or indications regarding lane usage, the center lane is typically designated for overtaking. This allows vehicles traveling in the outer lanes—usually intended for general traffic flow—to change lanes and pass slower vehicles in the middle lane without disrupting the flow of traffic.

Using the center lane for overtaking maximizes road efficiency and enhances safety by providing drivers with a clear option for passing. This principle is common in traffic regulations, emphasizing the importance of using designated lanes appropriately to maintain smooth traffic movement.

In this scenario, while other uses of the center lane, such as turning left or parking, may exist in different contexts, they are not applicable when no additional markings or traffic signals are present to indicate such functions. Thus, overtaking becomes the primary and most appropriate use for the center lane in this situation.
