Dense fog lets you see only a short distance ahead on a highway posted 55 mph. You slow to 50 mph, but at that speed you could not stop in time for a stalled car in the fog. Which statement is correct?
A travels on a two-lane road where dense fog hides the road ahead. The card states a 55 mph limit and A’s 50 mph speed, which is too fast to stop within the short visible stretch; no safe speed or stop point is selected.
Correct answer: You can be cited under the basic rule, because 50 mph is unsafe here.
Why
The basic rule applies on every road, at every hour. When you choose a speed, think about traffic, pedestrians, bicyclists, the road surface and width, intersections, weather and visibility. The rule never lets you go over the speed limit, but it often requires you to go well under it.
