B. When the right half of a roadway is closed to traffic while under construction or repair;

C. Upon a roadway divided into three marked lanes for traffic under the rules applicable thereon;

(Ord. 413 § 10-9.2, 1965)

A. The following rules shall govern the overtaking and passing of vehicles proceeding in the same direction, subject to those limitations, exceptions and special rules stated in this section:

1. The operator of a vehicle overtaking another vehicle proceeding in the same direction shall pass to the left thereof at a safe distance and shall not again operate to the right side of the roadway until safely clear of the overtaken vehicle.

2. The operator of a vehicle, about to be overtaken and passed by another vehicle approaching from the rear, shall give way to the right in favor of the overtaking vehicle, on suitable and audible signal being given by the operator of the overtaking vehicle and shall not increase the speed of his vehicle until completely passed by the overtaking vehicle.

B. No vehicle shall be operated to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction, unless such left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be made completely without interfering with the safe operation of any vehicle approaching from the opposite direction or any vehicle overtaken. In every event, the overtaking vehicle must return to the right-hand side of the roadway before coming within two hundred feet of any vehicle approaching from the opposite direction.

C. No vehicle shall at any time be operated to the left of the centerline on a roadway under the following conditions:

1. When approaching the crest of a grade or upon a curve in the highway where the driver's view is obstructed within such distance as to create a hazard in the event another vehicle might approach from the opposite direction;

2. When approaching within one hundred feet of or traversing any intersection or railroad grade crossing;

3. When the view is obstructed upon approaching within one hundred feet of any bridge, viaduct, or tunnel;

4. On any roadway marked with a solid double centerline.

B. Upon a roadway which is divided into three lanes, a vehicle shall not be operated in the center lane except when overtaking and passing another vehicle where the roadway is clearly visible and such center lane is clear of traffic within a safe distance, or in preparation for a left turn or where such center lane is at the time allocated exclusively to traffic moving in the direction that the vehicle is proceeding and is designated by official traffic-control devices.

C. Official signs may be erected and/or the pavement marked directing slow-moving traffic to use a designated lane or designating those lanes to be used by traffic moving in a particular direction regardless of the center of the roadway and operators of vehicles shall obey the directions of every such sign and markings.

D. Traffic-control devices may be installed, prohibiting the changing of lanes on sections of roadway, and drivers of vehicles shall obey the directions of every such device. (Ord. 413 § 10-9.8, 1965)

Whenever any highway has been divided into two or more separate roadways by medial strips, every vehicle shall be driven only upon the right-hand roadway and no vehicle shall be driven over, across, or within any such medial strips except through an opening in such strips or at a crossover or intersection; provided, however, that a driver who enters such opening, crossover, or intersection shall yield the right-of-way to approaching vehicles before emerging upon the adjacent roadway of such divided highway, unless otherwise instructed. (Ord. 413.1 § 1(c), 1965: Ord. 413 § 10-9.10, 1965)

A. The county engineer or the Maui District Engineer of the Department of Transportation of the state are authorized to determine those portions of any highway where overtaking and passing or operating to the left of the roadway would be especially hazardous, and the engineers may by appropriate signs or markings on the roadway indicate the beginning and end of such zones.

B. Where signs or markings are in place to define a “no-passing zone” as set forth in subsection A of this section, no driver shall at any time drive on the left side of the roadway within such no-passing zone or on the left side of any pavement striping designed to mark such no-passing zone throughout its length. (Ord. 413 § 10-9.7, 1965)

C. Motor vehicles being operated upon any roadway outside of a business or residential district in a caravan or motorcade, whether or not towing other vehicles, shall be so operated as to allow sufficient space between each such vehicle or combination of vehicles so as to enable any other vehicle to enter and occupy such space without danger. This provision shall not apply to funeral processions. (Ord. 413 § 10-9.9, 1965)

A. The operator of any vehicle upon a public highway before starting, turning, or stopping such vehicle shall first see that such movement or cessation of movement can be made in safety; then if any pedestrian may be affected by such movement, the operator shall give a clearly audible signal by sounding a horn or other warning device, and whenever the operation of any other vehicle may be affected by this movement, the operator shall give a signal plainly visible to the operator of such other vehicle of the intention to make such movement. Such visual signal may be given either by the use of the hand and arm in the manner provided in this section, or by means of a mechanical or electrical device which meets the requirements set forth in this section, and which has been approved by the chief of police; provided, however, that whenever a hand and arm signal would not be visible both to the front and rear of such vehicle, then such vehicle must be equipped with, and the visual signal must be given by, such a mechanical or electrical device.

B. Whenever the signal is given by means of the hand and arm, the operator shall indicate his intention to turn to the left by extending his hand and arm horizontally from and beyond the left side of the vehicle; his intention to turn to the right by extending his hand and arm upward and beyond the left side of the vehicle; and his intention to stop or to suddenly decrease speed by extending his hand and arm downward from and beyond the left side of the vehicle, showing the palm of the hand to the rear; provided, however, that in a right-hand drive vehicle, the operator shall indicate his intention to turn to the left by extending his hand and arm upward and beyond the right side of the vehicle; his intention to turn to the right by extending his hand and arm horizontally from and beyond the right side of the vehicle; and his intention to stop or to suddenly decrease speed by extending his hand and arm downward from and beyond the right side of the vehicle showing the palm of the hand to the rear.

C. The signal required in this section to be given before turning to the right or left, whether given by means of the hand and arm or by means of a mechanical or electrical device approved by the chief of police shall be given continually during the last one hundred feet travelled by the vehicle before turning.

D. Where both streets or roadways are one-way, both the approach for a left turn and a left turn shall be made as close as practicable to the left-hand curb or edge of the roadway.

E. In all cases where official marks, buttons, signs or directional arrows painted on the pavement are placed within or adjacent to intersections, no operator of a vehicle shall execute a movement at such intersections, otherwise than as directed and required by such marks, buttons, signs, or arrows.
