§ 1124. Limitations on overtaking on the left. 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
authorized by the provisions of this chapter and 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 completely
made without interfering with the operation of any vehicle approaching
from the opposite direction or any vehicle overtaken. In every event the
overtaking vehicle must return to an authorized lane of travel as soon
as practicable and in the event the passing movement involves the use of
a lane authorized for vehicles approaching from the opposite direction,
before coming within two hundred feet of any approaching vehicle.
