Texas Car / Permit practice question · Road Signs

A red, eight-sided (octagonal) sign means you must:

Red octagonal road sign

Answer choices

  • slow down and merge to the right
  • come to a complete stop before the stop line or crosswalk— Correct answer
  • sound your horn, then continue
  • stop only if another vehicle is coming

Why this is the answer

An octagon is used only for stop signs. It means you come to a complete stop, yield to pedestrians and other vehicles, then go on carefully, stopping behind the stop line or before the crosswalk. Slowing down is not enough, and the rule applies to every vehicle that reaches the sign, not just when cross traffic is coming.
