Tips to help your CT pass
Based on where CT models most often fail. For a full list, use our pre-MOT checklist.
Lights and electrics · 5.7% of CT tests
Walk round every light
With a helper, check headlights on dipped and main beam, sidelights, brake lights, indicators, the rear fog light and the number plate lamp. Replace blown bulbs in pairs and make sure no lenses are cracked.
Visibility · 3.1% of CT tests
Clear the view
Replace wiper blades that smear, fill the washer bottle and get chips in the windscreen repaired early, especially in the area directly in front of the driver.
Brakes · 2.7% of CT tests
Don't ignore brake warning signs
Grinding, squealing, a soft pedal or the car pulling to one side under braking are all worth investigating before the MOT. Check whether the last test noted worn pads or discs; if so, they may now be below the limit.
