Which lane is designated for passing slower vehicles on multi-lane roads?

The left lane is typically designated for passing slower vehicles on multi-lane roads. This lane allows faster-moving traffic to overtake vehicles that are traveling at slower speeds in the other lanes. In many regions, traffic regulations emphasize that vehicles should primarily use the right lane for regular driving and only move to the left lane when they intend to pass. This not only enhances the flow of traffic but also promotes safety by reducing the likelihood of sudden lane changes and minimizing disruptions in the traffic pattern.

Using the left lane for passing also means that once a driver has successfully overtaken a slower vehicle, they should return to the right lane as soon as it is safe to do so, allowing others to use the left lane for passing as well. Proper lane usage is essential for maintaining order on the road, and using the left lane specifically for passing is a common practice that drivers should observe.
