HCC §24-151
Minimum speed rules for driving on highways
Read the official text at hawaiicounty.gov ↗This section sets minimum speed rules. You must not drive so slowly that you block normal traffic, unless it is needed for safety or required by law. On roads with speed limits of 40 mph or more, you must not go more than 15 mph below the limit if you can help it. If you are going too slow, you must pull over to let others pass.

(a) No person shall drive a motor vehicle on a highway at such a slow speed as to impede the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or in compliance with law. (b) When a speed limit is set at forty or more miles per hour, the driver of a vehicle proceeding on such highway shall not operate the driver’s vehicle at a speed less than fifteen miles per hour below the posted speed limit whenever practicable except when necessary for safe operation. (c) No person shall drive a motor vehicle on a highway at a speed lower than the required minimum speed, if to do so would impede other vehicular traffic. Such person shall pull to the side of the highway wherever safe to do so and stop if necessary to allow other vehicles to pass the slow-moving vehicle. VEHICLES AND TRAFFIC § 24-152 Division 3.
