Final answer:
To ensure pedestrian safety, a motorist should yield the right of way at crosswalks, stop for pedestrians in marked and unmarked crosswalks, and exercise caution at intersections. Speeding up when approaching pedestrians is not a safe practice.
Step-by-step explanation:
To ensure pedestrian safety, a motorist should do all of the following, except for speeding up when approaching pedestrians to clear the road quickly. Speeding up near pedestrians can increase the risk of accidents and harm to pedestrians. Instead, it is important for motorists to yield the right of way at crosswalks, stop for pedestrians in both marked and unmarked crosswalks, and exercise caution at intersections.
