Driver's License Test Prep
Texas Practice Regulatory Signs

According to the Texas manual, how must drivers treat regulatory traffic signs?

  1. A.
    Obey them in the same manner as traffic laws. Correct
  2. B.
    Treat them as advisory unless a fine is posted.
  3. C.
    Obey them only during posted daylight hours.
  4. D.
    Follow them only when other drivers are present.
The Why

The answer is "Obey them in the same manner as traffic laws."

The manual treats a regulatory sign as the law itself, not as a posted suggestion. Choice B is the pull for a reader who has driven under yellow advisory speed panels and generalized advisory to the whole family: but a No U-Turn or No Left Turn sign carries the full force of statute.

Why the others miss

The traps in the wrong answers

B. Treat them as advisory unless a fine is posted.

Every regulatory sign is enforceable; the advisory category is a separate warning family. This answer generalizes from the yellow advisory speed panel to the whole regulatory table on the same page.

C. Obey them only during posted daylight hours.

Regulatory signs apply around the clock unless the sign itself carries a time plate. This answer carries the school-zone rule (the posted speed applies only when the yellow lights flash) over to every regulatory sign, expecting each to name its own hours.

D. Follow them only when other drivers are present.

The manual attaches the obligation to the sign itself, not to the presence of witnesses. This answer treats regulatory signs as social conventions and leans on an empty-road excuse the statute does not offer.
