The correct answer is C) about three to four times as high.
Traffic fatalities are about three to four times as high at night compared to daytime.
That is why it is of the utmost importance to drive carefully at night, totally focused on the wheel and the road ahead. Always respect the speed signs and other traffic signs on the streets and highways. Stop at intersections and make sure no pedestrians are crossing. Turn your head on both sides, and never, ever drive under the influence of alcohol.
