    • BSlow right down and go if the road is clear
    • CStop only when traffic is coming

    Correct answer: A

    Regulation 29 of the Road Traffic (Traffic Signs) Regulations 2025 provides that the stop sign indicates that traffic shall stop before entering a major road. Slowing and continuing, or stopping only when traffic is coming, does not meet that requirement, and the duty applies whichever way you are turning.

    • CStop only when traffic is coming

    Correct answer: B

    Under Regulation 29 of the Road Traffic (Traffic Signs) Regulations 2025, the stop sign still requires traffic to stop before entering the major road. A quiet junction and a clear view do not turn it into a yield, and the duty to stop does not depend on whether your view is blocked.
