Article 3. Overtaking And Passing
21750. The driver of a vehicle overtaking another vehicle or a bicycle proceeding in the same direction shall pass to the left at a safe distance without interfering with the safe operation of the overtaken vehicle or bicycle, subject to the limitations and exceptions hereinafter stated. 21751. On a two-lane highway, no vehicle shall be driven to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction unless the left side is clearly visible and free of oncoming traffic for a sufficient distance ahead to permit such overtaking and passing to be completely made without interfering with the safe operation of any vehicle approaching from the opposite direction. 21752. No vehicle shall be driven to the left side of the roadway under the following conditions: (a) When approaching or upon the crest of a grade or 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. (b) When the view is obstructed upon approaching within 100 feet of any bridge, viaduct, or tunnel. (c) When approaching within 100 feet of or when traversing any railroad grade crossing. (d) When approaching within 100 feet of or when traversing any intersection. This section shall not apply upon a one-way roadway. 21753. Except when passing on the right is permitted, the driver of an overtaken vehicle shall safely move to the right-hand side of the highway in favor of the overtaking vehicle after an audible signal or a momentary flash of headlights by the overtaking vehicle, and shall not increase the speed of his or her vehicle until completely passed by the overtaking vehicle. This section does not require the driver of an overtaken vehicle to drive on the shoulder of the highway in order to allow the overtaking vehicle to pass. 21754. The driver of a vehicle may overtake and pass to the right of another vehicle only under the following conditions: (a) When the vehicle overtaken is making or about to make a left turn. (b) Upon a highway within a business or residence district with unobstructed pavement of sufficient width for two or more lines of moving vehicles in the direction of travel. (c) Upon any highway outside of a business or residence district with unobstructed pavement of sufficient width and clearly marked for two or more lines of moving traffic in the direction of travel. (d) Upon a one-way street. (e) Upon a highway divided into two roadways where traffic is restricted to one direction upon each of such roadways. The provisions of this section shall not relieve the driver of a slow moving vehicle from the duty to drive as closely as practicable to the right hand edge of the roadway. 21755. (a) The driver of a vehicle may overtake and pass another vehicle upon the right only under conditions permitting that movement in safety. In no event shall that movement be made by driving off the paved or main-traveled portion of the roadway. (b) This section does not prohibit the use of a bicycle in a bicycle lane or on a shoulder. 21756. (a) The driver of a vehicle overtaking any interurban electric or streetcar stopped or about to stop for the purpose of receiving or discharging any passenger shall stop the vehicle to the rear of the nearest running board or door of such car and thereupon remain standing until all passengers have boarded the car or upon alighting have reached a place of safety, except as provided in subdivision (b) hereof. (b) Where a safety zone has been establilshed or at an intersection where traffic is controlled by an officer or a traffic control signal device, a vehicle need not be brought to a stop before passing any interurban electric or streetcar but may proceed past such car at a speed not greater than 10 miles per hour and with due caution for the safety of pedestrians. (c) Whenever any trolley coach or bus has stopped at a safety zone to receive or discharge passengers, a vehicle may proceed past such trolley coach or bus at a speed not greater than 10 miles per hour. 21757. The driver of a vehicle shall not overtake and pass upon the left, nor shall any driver of a vehicle drive upon the left side of, any interurban electric or street car proceeding in the same direction whether the street car is actually in motion or temporarily at rest, except: (a) When so directed by a police or traffic officer. (b) When upon a one-way street. (c) When upon a street where the tracks are so located as to prevent compliance with this section. 21758. In the event any vehicle is being operated on any grade outside of a business or residence district at a speed of less than 20 miles per hour, no person operating any other motor vehicle shall attempt to overtake and pass such slow moving vehicle unless the overtaking vehicle is operated at a speed of at least 10 miles per hour in excess of the speed of the overtaken vehicle, nor unless the passing movement is completed within a total distance not greater than one-quarter of a mile. 21759. The driver of any vehicle approaching any horse drawn vehicle, any ridden animal, or any livestock shall exercise proper control of his vehicle and shall reduce speed or stop as may appear necessary or as may be signalled or otherwise requested by any person driving, riding or in charge of the animal or livestock in order to avoid frightening and to safeguard the animal or livestock and to insure the safety of any person driving or riding the animal or in charge of the livestock.
