(a) The Office of the State Traffic Administration may determine those portions of any state highway where overtaking and passing or driving to the left of the highway would be especially hazardous and may by appropriate signs or markings on the highway indicate the beginning and end of such zones. A local traffic authority, as defined in § 14-297, may, in accordance with standards approved by the Office of the State Traffic Administration, determine and designate such no-passing zones on highways under its jurisdiction. When such signs or markings are in place and clearly visible to an ordinarily observant person, each driver of a vehicle shall obey the directions thereof. Except as provided in subsection (b) of this section, a violation of the provisions of this section shall be an infraction.

(b) The driver of a vehicle may overtake and pass, in a marked no-passing zone, pedestrians, parked or standing vehicles, animals, bicycles, electric bicycles, mopeds, scooters, electric foot scooters, vehicles moving at a slow speed, as defined in § 14-220, or obstructions on the right side of the highway, as listed in subdivision (2) of subsection (a) of § 14-230, provided such overtaking and passing may be conducted safely, with adequate sight distance and without interfering with oncoming traffic or endangering traffic, as defined in § 14-297.
