What is wrong on this page? One tap sends the category only, no text and nothing about you.
85.8% of first attempts passed in 2024 (1,506 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
Other sites may count retests or all attempts. This page uses 1,506 primary tests: 14.21% failed first time and 90.8% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 121 is shown separately.
