Hawaii's primary keep-right rule is found in Hawaii Revised Statutes §291C-41.
A vehicle traveling at less than the normal speed of traffic under the existing conditions generally must be driven in the right-hand lane available for traffic, or as close as practicable to the right-hand curb or edge of the roadway.
This slower-traffic rule does not apply when the driver is overtaking and passing another vehicle traveling in the same direction or when preparing for a lawful left turn at an intersection or into a private road or driveway.
Hawaii also has a specific turnout rule for two-lane roadways. If a vehicle is traveling 10 miles per hour or more below the posted speed limit, passing is not possible or permitted, and five or more vehicles are immediately following behind, the driver must move off the roadway at the nearest safe location where enough space exists for the trailing vehicles to pass.
The turnout requirement does not apply when pulling off the roadway would create an unsafe situation.
Hawaii therefore combines a traditional slower-traffic keep-right rule with a specific five-vehicle turnout requirement intended to prevent long traffic backups on two-lane roads.
Exceptions
- Overtaking and passing another vehicle traveling in the same direction.
- Preparing for a lawful left turn at an intersection or into a private road or driveway.
- Avoiding an obstruction when moving left is necessary and safe.
- Traveling on a roadway divided into three marked lanes under applicable lane rules.
- Traveling on a roadway designated and signposted for one-way traffic.
- For the five-vehicle turnout rule, pulling off the roadway would create an unsafe situation.
Penalties
Violations of Hawaii's keep-right and roadway-use requirements may result in a traffic citation.
The exact fine and total amount due depend on the specific violation and applicable court assessments. Drivers should verify the amount shown on the citation or with the court handling the case.
