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

Driving in the left lane of a highway is appropriate primarily when you are passing slower vehicles or when the right lane is closed. The left lane is typically designated as the passing lane, and its primary purpose is to allow faster-moving traffic to overtake slower vehicles safely.

When you encounter slower traffic in the right lane, the correct action is to use the left lane for passing. This helps maintain a smooth flow of traffic and reduces the risk of accidents caused by abrupt lane changes or sudden stops. Additionally, if the right lane is closed due to construction or other interruptions, using the left lane becomes necessary to continue your journey safely.

The other scenarios presented do not align with safe driving practices. For instance, exceeding the speed limit is unsafe and illegal, so driving in the left lane under such circumstances is inappropriate. Additionally, driving in the left lane merely because there is no traffic in the right lane does not justify using it, especially if you are not passing another vehicle. Lastly, while comfort is important, it should not dictate lane choice; adhering to traffic laws and ensuring safety should always be the priority.
