Based on the failure profile above, ten minutes with a torch before your test removes the most likely fail items:

Check tread with the 20p test and inspect sidewalls for cracking — tyres close to the limit are the country’s most common advisory
Replace smeared wiper blades and top up washer fluid — both are test items
Walk round with all lights on: one blown bulb is the most avoidable fail there is
Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
Check tread with the 20p test and inspect sidewalls for cracking — tyres close to the limit are the country’s most common advisory

Engine management light on?
