Hawaii has a basic speed limit rule that requires people to drive in a reasonable and prudent manner depending on traffic and weather conditions. Perhaps due to its rugged geography and narrow roads, Hawaii has the lowest maximum speed limit on any state in the U.S.

School zones              25 mph

Within city limits         25-45 mph

Highways                    45-55 mph

Interstate highways    60 mph


  • In some jurisdictions, U-turns will not be allowed but in general, it is legal to do so if you have good visibility in both directions and do not obstruct any traffic.

  • At traffic signals, you generally have to follow the arrow when turning.

  • Parking can be difficult in built-up areas such as Honolulu but you should have no problems in smaller towns and near attractions.

  • It is illegal to park on the sidewalk or in any way that blocks a driveway of any kind.

  • You should leave no more than 12 inches between your vehicle and the curb.

  • Double parking is not permitted.
