    You are travelling through a tunnel that is becoming congested. What should you do if you have to stop?

    DVSA-style practice question · Incidents, accidents and emergencies

    The answer options

    • Maintain a safe gap from the vehicle infrontCorrect
    • U-turn and find another route
    • Ignore any warning messages
    • Pull up close to the vehicle ahead to save space

    Why that is the answer

    When stopping in a congested tunnel, you must maintain a safe distance from the vehicle ahead, leaving at least a five-metre gap. This gives you enough space to manoeuvre if the vehicle in front breaks down or if an emergency vehicle needs to pass. Pulling up close to save space is dangerous because it locks you in and increases the risk of a chain-reaction collision if you are hit from behind.

    How this comes up in the real test

    Questions from incidents, accidents and emergencies appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.

    The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
