A warning sign is posted along a stretch of highway that becomes slippery when wet. What does the manual say about that particular stretch?
-
A.
It has been treated with a sealant that repels standing water.
-
B.
It may be more slippery than other road surfaces when wet. Correct
-
C.
Its posted speed limit automatically drops in wet weather.
The answer is "It may be more slippery than other road surfaces when wet."
A warning sign on a slippery stretch tells you that piece of road can be more slippery than the surfaces around it when wet, so slow before you reach it. Option C carries the manual's 5-to-10-mph wet-road reduction from the Basic Speed Law rule of thumb and applies it as if the posted number itself dropped, but the sign only flags the condition.
The traps in the wrong answers
A. It has been treated with a sealant that repels standing water.
Reads the sign as reassurance the surface is treated, when it warns the opposite. This answer assumes a yellow sign on a highway marks completed maintenance rather than an active hazard, so the warning is read as a courtesy notice and the driver does not slow down.
C. Its posted speed limit automatically drops in wet weather.
Treats the warning sign as an automatic speed-limit change, but the sign only flags the condition. This answer carries the 5-to-10-mph wet-road reduction from the Basic Speed Law drills and treats it as an automatic drop in the posted number.
