Read the first 6 Vehicle Safety Checks flashcards as text

  1. What should a driver check about the fuel/AdBlue levels during a walkaround check?

    Answer: Ensure both fuel and AdBlue are sufficient for the planned journey

    Both fuel and AdBlue (diesel exhaust fluid used in SCR emission systems) must be checked. Running out of AdBlue causes the engine to derate (reduce power) and can trigger a no-restart condition on some vehicles.

  2. During a pre-departure check, a driver finds a tyre has a bulge on the sidewall. What must they do?

    Answer: Do not drive — a bulged tyre must be replaced immediately

    A bulge on a tyre sidewall indicates internal structural damage. The tyre could fail catastrophically at any time and especially under load or speed. The vehicle must not be driven until the tyre is replaced.

  3. What is checked when testing the vehicle's horn during a walkaround inspection?

    Answer: That it sounds and is loud enough to be heard by other road users

    The horn must sound clearly and be audible. A working horn is a legal requirement. The driver should briefly sound it in a safe area to confirm it operates.

  4. An LGV driver checks the load and finds an axle weight may be overloaded. What should they do?

    Answer: Redistribute the load or refuse to drive until the weight issue is resolved

    Individual axle overloading is illegal even if the total vehicle weight is within limits. An overloaded axle can damage the road, cause handling problems, and result in prosecution. The load must be redistributed before driving.

  5. What should a driver check regarding the trailer's electrical connections?

    Answer: That both the ISO 7638 ABS/EBS connector and the 24N/24S lighting connections are fully engaged

    The driver must ensure all trailer electrical connectors are fully engaged: the ISO 7638 7-pin connector (for ABS/EBS brakes) and the 24N and 24S sockets (for lighting). Disconnected plugs mean no trailer ABS and no lights.

  6. What is the correct procedure when a driver discovers a defect during a journey?

    Answer: Stop safely as soon as possible, assess whether it is safe to continue, and report it to the operator

    If a defect is discovered mid-journey, the driver must stop safely when it is safe to do so, assess the severity of the defect, contact the operator, and decide whether the vehicle can continue safely or needs recovery.
