When is it permissible to drive in the left lane of a highway?

Driving in the left lane of a highway is primarily designated for passing other vehicles. This lane allows faster-moving traffic to safely overtake slower vehicles that are typically in the right lane. It is important to adhere to this rule to maintain traffic flow and ensure safety on the road.

When passing, it’s crucial to signal your intentions before changing lanes, check your mirrors and blind spots, and ensure that there is enough distance between your vehicle and the one you intend to pass. After successfully overtaking, drivers should return to the right lane when it's safe to do so, thus allowing other vehicles to use the left lane for passing as well.

Traveling in the left lane at all times, during heavy traffic, or simply when in a hurry does not align with safe driving practices or traffic laws, as these behaviors can lead to congestion and potentially dangerous situations on the road.
