Clocks Change 2026: How to Drive Safely as Nights Fall

Every fixture in the British motoring calendar has one big autumn moment that catches drivers out year after year: the clocks going back. It's not a new rule and nothing has changed about how it works, but it's worth a proper look because the safety impact on the roads is real, predictable, and largely avoidable if you know what's coming.

This year the change lands on Sunday 25 October 2026, when clocks move back an hour at 2am, according to GOV.UK. That's the moment British Summer Time ends and the country reverts to Greenwich Mean Time. For drivers, the practical upshot is simple: a commute that was daylight the Friday before is suddenly dusk or dark the following Monday. Your eyes, your routine and your reaction times haven't caught up yet, and that mismatch is exactly where the risk lives.

When do the clocks go back in 2026?

GOV.UK confirms the clocks go forward 1 hour at 1am on the last Sunday in March and back 1 hour at 2am on the last Sunday in October, every year, without exception. For 2026 that means the clocks go back on Sunday 25 October. There's no announcement to wait for and no year-to-year variation in the mechanism, only the specific date, which always falls on the final Sunday of the month.

The effect on your day is immediate. Sunset creeps forward by roughly an hour overnight, so a 5.30pm finish that was daylight on the Friday is dark by the following Monday. Mornings get lighter for a few weeks, then the natural drift of the season starts pulling sunrise later again too, and by December you're driving both ends of the commute in the dark.

Why does driving get riskier when the clocks go back?

This isn't a one-off blip, it's a well-documented seasonal pattern. RoSPA's Road Safety Observatory notes that road casualty rates increase with the arrival of darker evenings and worsening weather conditions, and every autumn when the clocks go back and the evenings become darker earlier, road casualties and the casualty rate rise. One piece of research cited in the same review found 10 per cent more RTIs killing or injuring a pedestrian in the four weeks following the clocks going back than in the weeks before it.

There are a few things stacking up at once here. Traffic volumes don't drop just because it's dark, the evening school run and rush hour still happen at the same clock time, only now under headlights rather than daylight. Drivers haven't adjusted their habits yet, so speeds and following distances often stay set for daylight conditions. And it's not just the dark itself, autumn brings wet roads, fallen leaves and low sun glare into the mix at the same time, which compounds the problem rather than replacing it.

Casualty patterns vary by year, region and road type, so for the latest official figures check the Department for Transport's reported road casualties statistics, and for current MOT lighting requirements check the DVSA's MOT inspection manual.

Practical steps to keep yourself and others safe

Get your lights and windscreen sorted

• Check both dip and full beam, indicators, brake lights, fog lights and number plate lights before the change, not after you've already been caught out in the dark.
• Clean the windscreen inside and out. A film of grime scatters oncoming headlights and makes glare far worse than it needs to be.
• Top up washer fluid and check your wiper blades. Wet, low-sun mornings are brutal on tired blades.

Adjust your driving to the dark

• Slow down slightly and increase your following distance. Reaction times and depth perception are both worse at night, even for experienced drivers.
• Give yourself more time for journeys you'd normally rush. A daylight ten-minute drive can easily take longer once you're navigating unlit lanes or wet roundabouts.
• Dip your headlights promptly for oncoming traffic and use fog lights only in genuinely poor visibility, not as an extra pair of headlights.

Watch for vulnerable road users

Pedestrians and cyclists are far harder to spot in low light, particularly in dark clothing on unlit roads. Slow down near schools, bus stops and residential streets in the early evening, when children and commuters are still moving around but the light has already gone.

Manage headlight dazzle

Glare from modern headlights is a genuine and growing complaint. RAC research quoted in Parliament found that Hansard records almost every driver thinks that some headlights are too bright, and more than half have been temporarily blinded by them. If you're dazzled, avoid staring directly at the oncoming lights, look towards the left edge of your lane and the white line instead, and slow down rather than swerving.

Headlight brightness standards and vehicle lighting rules are set out in the MOT inspection manual, so if you're worried about a specific fault, check the current requirements via DVSA rather than relying on general advice.

Getting your car properly ready for the dark months

Before the nights properly close in is a sensible time to look over any car you own or are about to buy. A quick check on registration can flag whether a car has picked up MOT advisories for lighting, tyres or wipers that you'd want sorted before winter, alongside its full test history, DVLA details and any outstanding safety recalls. You can run that for free using our reg lookup tool, which also gives you a market valuation as a rough guide if you're weighing up your options.

If you're looking at a used car specifically for the darker months ahead, whether that's something with better visibility, decent headlights or simply newer, it's worth going a step further than the free check. Our vehicle history check, with data provided by Experian, covers whether a car is recorded stolen, has been an insurance write-off, is carrying outstanding finance, its previous keepers, and whether it's been imported, exported or scrapped. That's the kind of background detail you genuinely want settled before you hand over any money, particularly on a car you're about to rely on through wet, dark winter commutes.

Thinking about a change before winter?

If your current car isn't giving you much confidence on dark, wet roads, autumn is a reasonable time to start looking. A free valuation gives you a starting point on what your existing car might be worth as a rough market guide, bearing in mind that actual figures vary with condition, mileage, spec and demand at the time. From there, if you decide a change makes sense, you can look at car finance options, subject to status and affordability, to help spread the cost of something more suited to the season ahead.

The bottom line

None of this is new, the clocks have gone back on the last Sunday of October for well over a century, but that doesn't make the safety dip any less real each year. The fix isn't complicated: check your lights and windscreen before the change lands, slow down and give yourself more space once the evenings turn dark, and stay alert for pedestrians and cyclists who are just as caught out by the switch as you are. A week or two of extra care while everyone adjusts goes a long way towards keeping the fifteen minutes after 25 October 2026 uneventful rather than eventful.
