Arkansas's primary left-lane and keep-right rule is found in Arkansas Code §27-51-301.
On a multilane highway, a vehicle generally may not be driven continuously in the left lane unless one of the statutory exceptions applies.
A driver may use the left lane when overtaking and passing another vehicle traveling in the same direction.
The left lane may also be used when the other lanes traveling in the same direction are closed because of construction or repair, when those lanes are in disrepair or otherwise unsafe to drive, or when the driver is preparing to exit the highway on the left.
Arkansas previously framed the rule mainly around impeding other traffic, but the law was strengthened in 2021 so that continuous left-lane travel itself is restricted unless an exception applies.
Arkansas therefore has one of the clearer keep-right laws: on a multilane highway, the left lane is generally for passing or other specific situations rather than ordinary continuous travel.
Exceptions
- Overtaking and passing another vehicle traveling in the same direction.
- All other lanes traveling in the same direction are closed because of construction or repair.
- All other lanes are in disrepair or otherwise unsafe or undrivable.
- Preparing to exit the multilane highway on the left.
Penalties
Violation of Arkansas's left-lane or keep-right requirements may result in a traffic citation.
The exact fine and total amount due can depend on the specific violation, court costs and applicable assessments. Drivers should verify the amount shown on the citation or with the court handling the case.
