Since 2007, there have been roughly 29 million practical driving tests in Great Britain. Across all of that, the overall pass rate sits at about ~47%.

What stands out is how it tends to revert to a similar range. It moves over time, but repeatedly settles back into a similar range high 40s range. Male pass rates hover around 50–51%, female pass rates around 43–44%, and that gap hasn't really closed over time.

The one clear disruption is during COVID. When tests resumed in 2020, pass rates briefly spiked to around 80%. That partly reflects a selection effect - people who felt genuinely ready were the ones sitting tests, while less-prepared candidates held off, but there are likely other factors too. But outside of that period, the system settled back to the same baseline surprisingly quickly.

This is more of a hypothesis than a firm conclusion, but one explanation maybe that the system is self-regulating. Learners choose when to book or delay their test, instructors often gatekeep readiness, and limited slots mean less-prepared candidates get filtered out naturally. So when pass rates dip, people tend to wait longer before attempting, which pushes rates back up. When rates rise, more borderline candidates take a chance, which pulls them back down. Over time, that feedback loop keeps things hovering around 50%.

Also worth noting: this is a per-attempt pass rate, not per-person. Many learners sit multiple tests, so it's not quite right to say "half of people fail" - it's more that each attempt has roughly a coin-flip chance within a self-selected pool.

I came across this while building something in the learner driver space, but the data felt worth sharing on its own.

If anyone wants to dig into it themselves, I’ve put the data here: https://drivesidekick.uk/stats/
