Observation, Speed & SpaceStandalone practice
A posted speed limit is 50 mph, but heavy rain makes the road difficult to see. How should you choose your speed?
Correct answer: Slow to a reasonable speed for the rain, even if it is below 50 mph
Why
A posted limit is a maximum for favorable conditions; a driver must use a lower reasonable speed when weather, visibility, traffic, or the road makes the maximum unsafe.
