This sign means?

- Dead end street ahead
- Slow moving vehicle ahead
- Stop sign ahead. Slow down ✓
- Yield right-of-way
Answer: C. Stop sign ahead. Slow down
This sign means a stop sign is ahead, so slow down and get ready to stop.
Why this is the answer
The handbook's list of common warning signs includes one whose stated meaning is that a stop sign is coming up and that you should slow down. Warning signs like this one tell you about a condition ahead so you can adjust before you reach it — here, easing off the speed and preparing to come to a complete stop at the stop line, crosswalk, sidewalk edge or intersection edge, whichever comes first. The passages don't describe this sign's shape or colour, so the meaning written in the warning-sign list is what you go on.
Why the other answers are wrong
- A. Dead end street ahead — Nothing in the passages lists a dead end street sign or says a warning sign tells you the road ends ahead.
- B. Slow moving vehicle ahead — A slow moving vehicle warning does not appear anywhere in the handbook passages provided, so it does not fit this meaning.
- D. Yield right-of-way — Yielding right-of-way belongs to the yield sign, which the handbook describes as a triangle with a white background and red border, a different sign with a different message.
Remember it
Warning signs give you time to react: if the message is a stop ahead, your foot should already be moving toward the brake.
