Right-Of-Way 
At intersections without traffic signals an approaching vehicle must 
yield the right-of-way to a vehicle which has entered the intersection 
from a different highway, and where the vehicles enter the intersec¬ 
tion at the same time the vehicle on the left must yield the right-of- 
way to the vehicle on the right. Where traffic signals are in operation 
vehicles proceeding on a green light, whether going straight ahead or 
turning, and vehicles turning to the right on a red light, must yield 
the right-of-way to other vehicles and to pedestrians lawfully within 
the intersection or adjacent crosswalks. Pedestrians crossing a high¬ 
way in obedience to a special pedestrian control signal have the right- 
of-way over all vehicles. Where no traffic or pedestrian control signals 
are in operation (a) pedestrians within marked crosswalks, or unmarked 
crosswalks at intersections, have the right-of-way over vehicles when 
the pedestrian is in the same path of the roadway as the vehicle or is 
approaching so closely from the opposite path as to be in danger, but 
no pedestrian may suddenly leave a curb or other place of safety and 
enter the path of a vehicle which is so close that it is impossible for 
the driver to yield; and (b) pedestrians crossing a highway at a point 
other than a crosswalk must yield the right-of-way to all vehicles, but 
the driver of the vehicle must nevertheless use due care for the safety 
of the pedestrian. Vehicles stopped at a crosswalk to permit a pedes¬ 
trian to cross the highway may not lawfully be passed by any other 
vehicle approaching from the rear. Vehicular traffic must yield the 
right-of-way to mounted persons crossing or about to cross a highway.
