A yellow advisory speed sign is posted below a curve warning sign. According to the Texas manual, what does the speed number tell you?
-
A.
The minimum speed required for vehicles on the curve
-
B.
The highest speed you can safely travel around the curve Correct
-
C.
The average speed of traffic recorded at the curve
-
D.
The maximum speed legally permitted on the curve
The answer is "The highest speed you can safely travel around the curve"
An advisory speed sign gives the highest speed at which you can safely travel around the curve ahead. Choice D is the trap because the yellow panel is easy to read as a legal limit; drivers do that when they overlook that Texas posts legal speed maximums on white regulatory signs, not yellow advisory ones.
The traps in the wrong answers
A. The minimum speed required for vehicles on the curve
The advisory speed is a safe-travel ceiling, not a required floor. This answer flips the direction of the number, borrowing the logic of a minimum-speed regulatory sign.
C. The average speed of traffic recorded at the curve
The advisory panel gives a safe-travel figure for the curve ahead, not a recorded traffic statistic. Confuses the yellow advisory panel with a radar speed-feedback display, which does show measured traffic speeds rather than a posted safe-travel number.
D. The maximum speed legally permitted on the curve
Legal maximum speeds are posted on white regulatory signs, not on yellow advisory panels. This answer reads every yellow speed number as an enforceable limit rather than a safe-travel guideline.
