There are established electric traffic-control devices, exhibiting successively, one at a time, green, yellow, red, and yellow lights or signals, or rapidly intermittent flashing red or yellow lights or signals, at each of the four comers of the intersections of M and Eighteenth Streets, and M and Nineteenth Streets in the city.

(Ord. 339 § 1, 1951)

While such traffic-control signals are in operation, traffic shall be regulated thereby in the following manner:

A.    Green Light.

1.    Vehicular traffic facing the signal may proceed straight through the intersection or tum right or left therein, but vehicular traffic shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection at the time such signal is exhibited.

2.    Pedestrians facing the signal may proceed across the street within any marked or unmarked crosswalk.

B.    Red Light or Yellow Light When Shown Immediately Following the Green Light.

1.    Vehicular traffic facing the signal shall stop before entering the nearest crosswalk at the intersection, and remain standing until green light is shown alone.

2.    Pedestrians facing the signal shall not enter that portion of the street, at the intersection, lying between curbs or curblines.

C.    Rapid Intermittent Flashes of Red Light. Vehicular traffic facing such signal shall stop before entering the nearest crosswalk at the intersection.

D.    Rapid Intermittent Flashes of Yellow Light. Vehicular traffic facing such signal may proceed through the intersection only with caution.
