Where it fails

Each area compared with a typical car of the same age and mileage, in points of pass rate. Tap or hover an area to see what to check.

Exhaust: 0.0% of tests fail on emissions & leaks, against 0.7% for a typical car of the same age and mileage. Listen for a blowing exhaust at start-up and look underneath for oil or fluid leaks.Suspension: 0.1% of tests fail on suspension, against 1.1% for a typical car of the same age and mileage. Listen for knocks over speed bumps and push each corner down: it should settle at once.Lights: 1.2% of tests fail on lights & electrics, against 2.8% for a typical car of the same age and mileage. Walk round the car with every light on, including brake, fog and number plate lights.Tyres: 3.1% of tests fail on tyres, against 4.8% for a typical car of the same age and mileage. Check the tread on every tyre, including the inner edge, and look for cuts or bulges.Brakes: 0.3% of tests fail on brakes, against 2.0% for a typical car of the same age and mileage. Brake firmly on the test drive: the car should stop straight with no pulsing or grinding.Lights: 1.2% of tests fail on lights & electrics, against 2.8% for a typical car of the same age and mileage.

Buying one or MOT due? Check these

  • Tyre damage & cracking
    Look for cuts, bulges and cracking on both sidewalls of every tyre.
  • Windscreen wipers
    Test the washers and wipers: a cheap fix, but a very common MOT fail.
  • Headlight aim
    Park facing a wall at night: both dipped beams should sit level and dip to the left.
  • Tyre tread depth
    Check every tyre, including the inner edge, has at least 3 mm of tread. Uneven wear can point to alignment or suspension problems.
  • Tyre pressure warning (TPMS)
    Make sure no tyre-pressure warning light stays on after start-up.
  • Brake pads
    Ask when the pads were last replaced and look for a brake-wear warning on the dash.
