Which lane is designated for passing slower vehicles on multi-lane roads?

The left lane is designated for passing slower vehicles on multi-lane roads. This is a standard traffic rule not only in Utah but in many places across the United States. The left lane is typically reserved for faster-moving traffic and overtaking slower vehicles, while the right lanes are generally used for slower traffic and those preparing to exit or turn. This structure helps to maintain an efficient flow of traffic and reduces the likelihood of accidents caused by frequent lane changes.

Using the left lane for passing is crucial for safety, as it allows faster vehicles to overtake without having to weave in and out of traffic, which can lead to collisions. In situations where the left lane is blocked or occupied, drivers should wait until it is safe to pass while maintaining their speed within the posted limits in the right lanes. This ensures that all vehicles are moving harmoniously, keeping roadways safer for everyone.
