When is a driver prohibited from using the left lane on a highway?

A driver is prohibited from using the left lane on a highway primarily when that lane is not intended for passing. In many jurisdictions, including Georgia and other states, the left lane is designated as a passing lane, and its primary purpose is to allow faster vehicles to overtake slower ones. Using this lane for purposes other than passing can lead to safety issues, such as impeding traffic flow and increasing the likelihood of accidents as drivers behind may become frustrated and attempt to pass on the right.

The intent behind this regulation is to maintain smooth traffic flow and enhance safety for all road users. Therefore, if a driver is riding in the left lane without the intention to pass, they may be disrupting the normal operation of the roadway, which can lead to traffic violations and possible penalties.

While driving at a slower speed can be a reason for not using the left lane, it's specifically about the lane's intended purpose for passing that is at the heart of this regulation. Similarly, the conditions of traffic or the distance of the trip are not relevant aspects for the prohibitions regarding left lane use.
