What does the extreme left lane law refer to?

The extreme left lane law refers to the regulation that allows drivers to use the leftmost lane primarily for overtaking or passing other vehicles. This means that the left lane is intended for those who want to move faster than the flow of traffic, enabling safer and more efficient driving conditions.

By allowing its use for overtaking, the law aims to keep faster-moving vehicles in a designated lane, which can help reduce congestion and improve the overall flow of traffic. It is essential for drivers to understand that while they may use the left lane to pass, they should return to a right lane after completing the maneuver, ensuring that the left lane remains accessible for others who may need to overtake as well.

This understanding encourages responsible use of the roadway and helps maintain safety standards on highways. The other options do not accurately reflect the purpose of the extreme left lane law and may lead to misunderstandings about proper driving practices.
