This sign means?

- Two-way traffic ahead
- Traffic may travel in one direction only ✓
- One-way traffic ends
- Do not turn right
Answer: B. Traffic may travel in one direction only
The sign means that traffic may travel in one direction only.
Why this is the answer
The handbook lists this among common regulatory signs and states that traffic may travel in one direction only. Regulatory signs give a direction that must be obeyed, so when you see this sign you should understand that vehicles are permitted to move only one way along that road or lane. It does not announce two-way traffic ahead, and it does not mark the end of a one-way section; it confirms that travel is one-way.
Why the other answers are wrong
- A. Two-way traffic ahead — The passage says traffic may travel in one direction only, not that two-way traffic is coming ahead.
- C. One-way traffic ends — The sign confirms one-way travel; the passage does not say it marks the end of one-way traffic.
- D. Do not turn right — The passage gives no right-turn prohibition for this sign, so it is not a do-not-turn-right sign.
Remember it
Link the sign to the phrase 'one direction only' — that is the whole rule, not a warning of a change ahead.
