What lane must drivers use on the highway for passing?

Drivers are required to use the left lane on the highway for passing slower vehicles. This is because the left lane is designated as the passing lane, where drivers can safely maneuver around vehicles that are traveling at lower speeds. By using the left lane for passing, it promotes the smooth flow of traffic and reduces the chances of accidents caused by sudden lane changes. This practice is common in many states, including Nevada, where keeping the right lane for slower traffic and using the left lane for overtaking helps maintain an orderly and efficient driving experience.

The right lane is often utilized for vehicles traveling at or below the speed limit, while the middle and shoulder lanes serve different functions and are not typically designated for passing.
