A white sign with a red circle and a slash through a symbol means:
-
A.
The action shown is recommended.
-
B.
The action shown is a warning.
-
C.
The action applies only at posted times.
-
D.
The action shown is prohibited. Correct
The answer is "The action shown is prohibited."
A red circle with a slash through a symbol is the universal prohibition mark: it tells you the action shown inside the circle is not allowed (no left turn, no right turn, no U-turn, and so on). Recommendations and advisories do not use a slashed circle, warnings use yellow diamonds, and time-of-day limits are spelled out in text on regulatory signs. Choice A flips the sign's meaning entirely, reading the slashed circle as an endorsement of the pictured action when the mark exists precisely to forbid it.
The traps in the wrong answers
A. The action shown is recommended.
Recommendations and advisories are not marked with a slash. The slash indicates prohibition. This answer inverts the prohibitive meaning of the slashed red circle, treating a 'do not' marker as an endorsement.
B. The action shown is a warning.
Warnings use yellow diamond signs, not a red circle with a slash. This answer confuses prohibitive regulatory signs (red circle and slash) with the separate category of warning signs.
C. The action applies only at posted times.
Time restrictions are written out in text on regulatory signs, not shown by the slashed circle. This answer reads a time-of-day qualifier into the slashed circle, which the manual treats as an unconditional 'do not' instruction.
