When driving at safe speeds on an expressway, what should lane selection allow for?

Lane selection while driving at safe speeds on an expressway is crucial for maintaining a smooth flow of traffic and ensuring safety for all drivers. The correct focus of lane selection is to allow vehicles to pass on the left. This practice conforms to the convention that the left lane is primarily used for overtaking slower traffic. By keeping the left lane available for passing, drivers can efficiently navigate around vehicles traveling at slower speeds in the right lanes, which helps to reduce congestion and maintain a more uniform traffic speed.

Considering the context of expressway driving, choosing lanes that facilitate this type of passing ensures that drivers can maneuver safely while keeping an eye on traffic dynamics. Effective lane selection creates an environment where vehicles can flow together without significant disruption, aiding both safety and traffic efficiency.

When lane selection does not prioritize allowing vehicles to pass on the left, it could lead to unintended hazards, such as tailgating or abrupt lane changes, as drivers may become frustrated with slower vehicles blocking their passage. Thus, the importance of selecting lanes thoughtfully cannot be understated in promoting safe driving practices on expressways.
