The Texas manual lists three actions to take when you encounter a warning sign. Which action is on that list?
-
A.
Reduce speed to at least the posted speed signs Correct
-
B.
Maintain your current speed until you see the hazard
-
C.
Come to a complete stop before continuing
-
D.
Move to the outside lane if one is available
The answer is "Reduce speed to at least the posted speed signs"
The manual's three-step response to a warning sign is pay attention, follow instructions, and reduce speed to at least the posted speed. Choice C is the trap: a reader carries over the complete-stop rule from octagon stop signs, but a yellow diamond calls for slowing, not a full stop.
The traps in the wrong answers
B. Maintain your current speed until you see the hazard
The manual asks you to slow before the hazard, not to wait until you see it. This answer treats yellow diamonds as pure heads-up notices, waiting for the hazard to appear before adjusting speed.
C. Come to a complete stop before continuing
The manual calls for a speed reduction at a warning sign, not a complete stop. This answer applies the full-stop response learned from octagon stop signs to every yellow diamond hazard.
D. Move to the outside lane if one is available
Moving over is the response to a stopped emergency vehicle, not to a warning sign. This answer confuses the three warning-sign actions with the Slow Down or Move Over law taught in a different chapter.
