Do UK Driving Test Pass Rates Vary by Time of Day?

#The pattern in the data

Aggregated DVSA data shows a small but consistent variation in pass rates across the day:

• Early morning (8:00 to 9:30): ~46% pass rate
• Late morning (10:00 to 11:30): ~50% pass rate
• Early afternoon (12:00 to 14:30): ~48% pass rate
• Late afternoon (15:00 to 16:30): ~46% pass rate
• Evening slots (after 16:30, weekday £75): ~47% pass rate

The total spread between best and worst time blocks is around 4 percentage points.

#Why late morning is the sweet spot

Several things converge between 10am and 11:30am:

• Rush-hour traffic has eased, reducing the chance of stressful junction moments
• Daylight is reliably full, no glare or visibility issues
• Examiners are at their alertness peak, fresher than late afternoon
• School-run traffic has cleared from residential routes
• Candidates have time to wake up properly without losing the day

#Why early morning is harder

Tests starting before 9am hit two problems: rush-hour congestion on routes, and candidate grogginess. Pass rates dip slightly even though traffic congestion can sometimes work in your favour by slowing the pace of the test.

#Why late afternoon is harder

After 3pm, you face the school run, returning commuter traffic, and (in winter) fading daylight. Examiner fatigue is also a small factor, although DVSA distributes the most demanding tests across the day to limit this effect.

#Time-of-day vs centre choice

A 4-point time-of-day swing is meaningful but small compared with the 35-point gap between best and worst centres. Choose your centre first, then optimise time of day within whatever slots are available. Do not sacrifice a good centre for a "better" hour at a worse one.

#Practical implications

• When booking, if multiple slots are available, prefer 10am to 11:30am where possible
• Avoid booking immediately after a heavy lunch or early in the morning if you struggle to wake up
• Match the time of your lessons to the time of your test for the final two weeks
• Do not pay extra for an evening or weekend slot if a weekday morning is available, the pass rate is no higher

#When time of day matters most

The effect is largest at busy urban centres, where rush-hour traffic genuinely complicates the drive. At rural centres, the time of day barely shifts the pass rate. If you are testing in central Birmingham or inner London, hour selection is worth the effort. If you are testing in Lerwick, it is noise.
