What is the manual's rule for choosing your driving speed at night?
-
A.
Never above forty-five miles per hour after sunset
-
B.
The same speed you would drive by daylight
-
C.
Slow enough to stop within the distance you can see ahead Correct
-
D.
Ten miles per hour under the posted daytime limit
The answer is "Slow enough to stop within the distance you can see ahead"
Night speed is bounded by how far ahead you can see, not by a fixed mph figure. Drivers who expect the manual to print a night-only cap the way daylight rules use a posted number reach for A on that expectation.
The traps in the wrong answers
A. Never above forty-five miles per hour after sunset
The manual sets no fixed nighttime mph cap; it ties night speed to what the driver can see. This answer expects the manual to print a night-only speed number the way daylight rules use a posted figure.
B. The same speed you would drive by daylight
The manual specifically shortens night speed to match reduced visibility, not to match daylight speeds. This answer ignores the visibility-based rule the manual sets to override daytime habits at night.
D. Ten miles per hour under the posted daytime limit
The manual does not print a 10 mph nighttime discount; speed is set by visible distance, not a fixed subtraction. This answer invents a fixed nighttime discount from the posted number, a rule of thumb the manual never states.
