What is the purpose of the left lane when there are three or more lanes going in one direction?

• A. To allow for slower traffic
• B. To facilitate merging
• C. To go faster or turn left
• D. To park temporarily

Answer: (C)

The left lane on a multi-lane road is primarily designated for faster-moving traffic and is often utilized for passing slower vehicles as well as for making left turns. This design helps maintain smooth traffic flow, allowing drivers who wish to travel at higher speeds or those needing to change lanes more efficiently to do so without disrupting the pace of vehicles traveling more slowly in the right lanes. Understanding this function encourages safe driving practices, such as using the left lane primarily for overtaking and not for regular travel at slower speeds. The other options do not align as clearly with the intended use of the left lane. For instance, the left lane is generally not meant for slower traffic, as slower vehicles should remain in the right lanes to help avoid congestion. Merging typically occurs in the rightmost lanes, as that is where entering traffic most commonly joins the roadway. Lastly, parking temporarily does not apply to the left lane usage, as parking should be conducted in designated areas away from moving traffic for safety reasons. Thus, the left lane's role in facilitating faster speeds and left turning provides a clearer understanding of its purpose on the roadway.
