Passes and fails are only half the story — advisories and defect codes build the wear picture.
These summaries cover 1,185,934,320 defect records linked to MOT tests. That includes advisories, minors, majors, and dangerous items coded to the DVSA manual.
Brand and model pages group those defects into owner maintenance, wear-and-tear, and systemic patterns — so you see why a model struggles at MOT, not just that it failed.
Free tools on CARMOTIQ show previews; deeper defect detail unlocks with credits. The underlying MOT facts stay the same either way.
