the half of the roadway upon which the vehicle is traveling, or when

the pedestrian is approaching so closely from the opposite half of

the roadway as to be in danger.

(b) No pedestrian shall suddenly leave a curb or other place of

safety and walk or run into the path of a vehicle which is so close

that it is impossible for the driver to yield.

(c) Paragraph (a) shall not apply under the conditions stated in

Section 11-503(b).

(d) Whenever any vehicle is stopped at a marked crosswalk or at

any unmarked crosswalk at an intersection to permit a pedestrian to
