On a three-lane road, what is the primary function of the right lane?

The right lane on a three-lane road primarily serves the purpose of accommodating slower-moving traffic, and it's also designed for vehicles that need to enter or exit the roadway. This lane is typically where vehicles are more likely to make right turns or merge into and out of traffic.

Drivers using the right lane can feel more comfortable traveling at or below the speed limit, which is essential for safety as they approach intersections or driveways. In contrast, other lanes are often intended for faster-moving traffic, particularly the middle lane, which is used for through traffic, while the left lane is primarily reserved for passing or overtaking slower vehicles.

Understanding the specific function of each lane helps maintain smooth traffic flow and enhances safety on the roadway.
