Pre-Trip Check Before an Airport Run
At 5:40 a.m. you are due to drive a friend's 2012 diesel SUV from Portsmouth to Douglas-Charles Airport, a trip of about an hour, for a 7:30 a.m. check-in. Overnight rain was heavy. During your walk-around you find: the front-left tyre has a bulge on the inner sidewall; the spare is inflated but its tread is near the legal minimum; the brake fluid reservoir is at the MIN mark; the driver's wiper blade leaves a large smeared arc; the windscreen has a 10 cm crack along the bottom edge on the passenger side; the fuel gauge is just under half. The owner says the SUV 'always smells a bit of diesel' and that the brake warning light came on briefly last week but went out. You are the only available driver.
1. Which of these findings make the vehicle a no-go, and which are lesser defects to fix before driving?

The no-go items are the tyre bulge and the brake findings. A bulge in a sidewall means the tyre structure is damaged; it can fail at any speed, and a spare with tread near the legal minimum is not a proper long-trip replacement on wet roads. Brake fluid at MIN plus a history of the brake warning light is a hydraulic-system warning; the vehicle should not be driven until the leak or fault is found. The smeared wiper and the crack are lesser but still relevant: the wiper impairs vision in rain, and a crack can spread. The diesel smell needs checking for a leak. Half a tank of fuel is not a defect, but it is not the deciding issue. The correct decision is not to take the airport run in this vehicle.
2. What should you do about the airport trip and the owner's 'it always smells of diesel' comment?
Read the worked answer
Do not drive the SUV. The airport deadline does not override a known tyre or brake defect. Arrange a licensed alternative driver, a taxi, or a borrowed vehicle, and tell the owner specifically which items failed: the sidewall bulge, the brake fluid level and the warning light, and the diesel smell. Ask the owner not to authorise the vehicle for use until a mechanic has inspected the brakes and the fuel system. If you are pressured to drive, refuse and record the reason. Before any later trip, recheck tyre pressures and condition, brake fluid, wipers, lights and the crack; a crack in the swept area or one that grows is a replacement issue. A pre-trip check is only useful if a defect actually changes the plan.
