On a highway with three or more lanes going in one direction, which lane should fast-moving vehicles use?

Fast-moving vehicles should use the left lane on a highway with three or more lanes going in one direction. This lane is often referred to as the “passing lane.” It is designated for vehicles that are traveling at higher speeds or are overtaking others.

Using the left lane for faster vehicles helps to maintain the flow of traffic and ensures that drivers can easily pass slower-moving vehicles that are typically found in the right or middle lanes. It is important to be aware of speed limits and traffic signs when using this lane. Keeping faster traffic in the left lane reduces the risk of accidents and improves overall highway safety.

The right lane is generally reserved for slower vehicles, merging traffic, or those preparing to exit the highway. The middle lane often serves as a buffer between slower traffic and faster-moving vehicles but is not specifically intended for high-speed travel. The emergency lane is designated for emergency vehicles and should not be utilized for regular driving, as it may obstruct emergency response operations and pose safety risks.
