When is it permissible to drive in the left lane of a multi-lane road?

Driving in the left lane of a multi-lane road is generally permissible when passing another vehicle. This practice is critical for maintaining smooth traffic flow and ensuring safety on the roads. The left lane is typically designated for faster-moving traffic and overtaking slower vehicles. By passing on the left, drivers can minimize disruptions and help alleviate congestion that might arise if many vehicles are attempting to switch lanes inappropriately. Thus, using the left lane for its intended purpose not only follows traffic regulations but also promotes safe driving habits.

Other scenarios, such as merging with traffic or navigating around construction zones, may require specific considerations and appropriate lane usage that typically prioritizes safety and the effective flow of vehicles.
