This sign means?

- You must come to a complete stop and do not proceed until safe ✓
- Bump 150 meters ahead
- Stop 150 meters ahead
- Stop only if other vehicles are approaching
Answer: A. You must come to a complete stop and do not proceed until safe
The sign means you must come to a complete stop and not go on until it is safe.
Why this is the answer
The handbook says a stop sign requires a complete stop. It tells you to stop at the marked stop line, or at the crosswalk, sidewalk edge or intersection edge if no line is painted, and to enter only after checking that the way is clear. That matches the answer: come to a full stop first and go on only when it is safe. The passages say nothing about a bump or a sign set 150 metres ahead, so those choices are not supported.
Why the other answers are wrong
- B. Bump 150 meters ahead — The passages do not describe any sign warning of a bump 150 metres ahead, so this meaning is not supported.
- C. Stop 150 meters ahead — No passage mentions a 150-metre distance for a stop sign; the rule is to stop at the sign location.
- D. Stop only if other vehicles are approaching — The handbook requires a complete stop, not a stop only when other vehicles are approaching.
Remember it
Full stop first, clear look second.
