Winter Van Checks: UK Rules for Fleets (2026)

Winter van checks matter more from late October onwards. The clocks went back on 25 October 2026, so more drivers are now starting or finishing their shifts in the dark, often on wet or icy roads. The legal rules are clear, and most are already part of a proper daily walkaround check.

What does the law say about driving a van in winter?

There are no separate winter rules for vans, but cold, dark weather makes the year-round duties easier to break. The Highway Code rules on adverse weather say that before you set off you MUST be able to see, so you must clear all snow and ice from all your windows, and you MUST make sure lights are clean and number plates are clearly visible and legible.

Those rules are backed by law:

• Regulation 30 of the Road Vehicles (Construction and Use) Regulations 1986 requires all glass to be maintained so that it does not obscure the driver's vision while driving on a road.
• Regulation 23 of the Road Vehicles Lighting Regulations 1989 says a vehicle must not be used on a road unless its required lamps, reflectors and devices are in good working order and, for lamps, clean.

Do I have to clear snow off the van roof?

The Highway Code says drivers should remove all snow that might fall off into the path of other road users, and should make sure mirrors are clear and windows thoroughly demisted. That wording is "should" rather than "MUST", so it is advice rather than a stand-alone legal requirement. Windows, lights and number plates, however, are covered by the "MUST" rules above.

What is the legal tyre tread depth for vans?

For vans with a maximum gross weight up to 3,500kg, and zero-emission vans up to 4,250kg, regulation 27 of the Construction and Use Regulations sets a minimum tread depth of 1.6mm. It must be met across a continuous band covering the central three-quarters of the tread and around the entire circumference of the tyre.

DVSA's van daily walkaround check guidance asks drivers to check that tyres have a legal tread depth, are inflated correctly, have no deep cuts on the sidewall or tread, and show no wire or cord. It also warns that you can get 3 penalty points on your licence for each tyre that is not safe and legal. Grip matters most in winter: the Highway Code says stopping distances will be at least double in wet weather and can be ten times greater on icy or snowy roads.

Which walkaround check items matter most in winter?

All of DVSA's checklist still applies, but these items are the ones winter weather hits hardest:

• Windscreen and glass: not damaged or obscured, with nothing in the swept area of the wipers.
• Washers and wipers: working correctly and in good condition.
• Lights and indicators: all working, with lenses fitted, clean and the right colour.
• Mirrors and cameras: in place, working and not obscured.
• Tyres: legal tread depth, correct pressure and no damage.
• Battery: secure, in good condition and not leaking.
• Number plates: secure and easy to read.
• Fluids: coolant, windscreen washer fluid and other levels correct, with no leaks.

On dark mornings a rushed check by torchlight can easily miss a failed bulb or a worn tyre, so asking for photos of tyres and lights helps.

What happens if a van is stopped with a winter defect?

DVSA's guidance says police and DVSA officers can stop and check your vehicle. If it is dangerous, DVSA can stop you using it until the problem is fixed, and you may be fined, prosecuted or given penalty points. Using a van in a dangerous condition can lead to an unlimited fine and a prison sentence. Our guide to S-marked prohibitions explains what happens when a defect should have been obvious at the walkaround, and our article on LED headlight bulbs and the MOT covers a common lighting question.

How can fleets keep winter checks consistent?

If your business has an operator licence, DVSA says drivers should record and report defects, and record "nil" defects when nothing is found. For everyone else it is good practice. A van check app gives drivers the same checklist every morning, captures photos and timestamps, and sends defects straight to the person who needs to fix them.
