The Driver's Handbook names one combination of conditions that "often initiate a collision" with pedestrians. What is it?

Correct answer: D. Twilight combined with pedestrians in dark clothing

Twilight plus dark clothing. The Handbook's words are: "Pedestrians in dark clothing, especially at night, are difficult to see. Extra care is needed when driving in low-light conditions. Twilight and dark clothing often initiate a collision." The two problems compound each other — at twilight your headlights are not yet doing much work but your eyes have already lost their daytime sharpness, and a person in dark clothes returns almost none of what light there is. The same section warns to "be extra cautious at twilight when children may still be playing outside, but are difficult to see." This is not a rule with a number attached; it is a cue to slow down and look harder at a specific time of day.
