Every year, when the clocks go back on the last Sunday in October, the darker evenings bring more than just a chill in the air — they bring increased road risk too.
For fleet drivers and managers, this seasonal shift can mean a sudden rise in collisions, changes in driver behaviour, and extra challenges keeping vehicles roadworthy and compliant.
Let’s explore what you can do to prepare, and how Fleet Service GB can help your business stay safe and efficient through the darker months.
Why the Clock Change Matters for Fleets
When we switch from British Summer Time (BST) to Greenwich Mean Time (GMT), daylight fades earlier. The evening rush hour — when roads are busiest — suddenly takes place in near-darkness.
According to recent figures from the AA and Fleet News, there’s typically an 11% increase in crashes in the weeks following the clock change, particularly between 4pm and 7pm.
Darker evenings, glare from low sun, slippery roads and driver fatigue all combine to create risk. For fleet operators, this means higher chances of rear-end shunts, minor collisions, and downtime — all of which can hit productivity and profit.
Key Risks for Fleet Drivers and Managers
Reduced Visibility and Glare
As the light fades earlier, drivers spend more time behind the wheel in the dark. Glare from headlights, low winter sun and dirty windscreens can all make it harder to spot hazards.
What to do:
- Check all vehicle lights weekly and replace bulbs immediately.
- Clean windscreens inside and out to reduce reflections.
- Encourage drivers to use anti-glare or polarised glasses if needed.
Changing Driving Conditions
Autumn weather can be unpredictable — wet leaves, rain, fog and icy patches all affect grip and braking distance.
What to do:
- Make sure tyres and brakes are in top condition.
- Encourage slower speeds and longer following distances (at least four seconds).
- Review route timings to avoid peak risk periods after dark.
Driver Fatigue
The darker mornings and shorter days can impact sleep patterns and alertness. Fatigued drivers are slower to react and more prone to errors.
What to do:
- Schedule regular breaks on longer routes.
- Use telematics data to monitor and manage driver fatigue.
- Run seasonal driver briefings to refresh awareness and safety habits.

FAQs About Daylight Savings and Fleet Safety
When do the clocks go back in the UK?
The clocks go back one hour at 2am on the last Sunday in October, marking the end of British Summer Time (BST) and the start of Greenwich Mean Time (GMT).
Why does road risk increase after the clocks go back?
Because dusk and darkness fall earlier, visibility drops and fatigue sets in sooner. Drivers often aren’t fully adjusted to the time change, leading to slower reactions and higher accident rates.
How can fleets reduce the risk of accidents?
Carry out regular vehicle checks, update driver training, and plan routes carefully. Encourage safe speeds and longer following distances to give drivers more reaction time.
How can Fleet Service GB help during seasonal changes?

Yes. FSGB offers a wide range of driver training modules, including courses on driving in low light and poor weather conditions — helping your drivers stay safe and confident through autumn and winter.
