With weather forecasters predicting further cold conditions across the UK, DAF Trucks is urging operators to intensify winter vehicle preparations and daily maintenance checks following record demand for its DAFaid roadside assistance service since the New Year.
The industry-benchmark DAFaid service experienced unprecedented winter demand, with the network successfully covering 898 jobs on Monday 5th January; the highest single-day volume ever recorded. The following day delivered the third-highest volume on record with 777 jobs. Across December, DAFaid received 9,024 calls for assistance, resulting in 7,902 jobs for the DAF network.
“That first Monday in January saw exceptional performance across the DAF network,” reports DAFaid Manager, Andy Mudie, “At one point we had 70 jobs awaiting dispatch. The response was brilliant. I’m proud of how DAFaid worked collaboratively to handle this remarkable demand, and their cooperation was crucial to achieving that record day.”

DAF Trucks emphasises that the majority of winter breakdowns requiring DAFaid assistance are entirely preventable through systematic winter preparation and rigorous daily walk-around checks. Analysis from National Highways reveals that tyres consistently account for 19.1% of winter breakdowns, while battery-related failures represent a further 18%. Cold weather compounds these vulnerabilities, reducing tyre pressure and grip while placing additional stress on electrical systems.
With winter demand reaching record levels, DAF encourages operators to utilise local DAF Dealer triage services for minor issues rather than calling roadside assistance. “Calling out a roadside technician for straightforward items like top-ups or fuse replacements comes at a cost and ties up resources,” Mudie explains. “During peak periods, this means genuine breakdown assistance is delayed while technicians travel to replace wiper blades or fuses. Many simple maintenance tasks can be conducted without roadside emergency services.”
Tyres remain the primary concern. Operators should check tread depth meets the 1mm legal minimum across three-quarters of the tyre width, though DAF recommends 3-4mm for winter conditions. Cold weather reduces both tyre pressure and grip, making regular pressure checks against manufacturer specifications essential. Inspect for cuts, bulges or exposed cords, and ensure spare tyres and chains are available.
Battery and electrical systems face increased demands in winter. Batteries older than three years, or those left at low charge levels over time, present higher failure risk. Check battery charge levels, inspect terminals for corrosion and examine all wiring, connections and earth straps. Slow cranking on start-up indicates reduced battery capacity requiring immediate attention. Cooling systems require antifreeze protection to at least -34°C. Test antifreeze strength, inspect coolant hoses for cracks or bulges, check coolant levels, and examine radiators for debris, leaks or corrosion signs.
Fuel systems are vulnerable to diesel waxing in cold conditions. Use winter-grade diesel where required, check fuel filters and replace if approaching service life, drain water separators to prevent freezing, and consider anti-waxing additives for extreme temperatures.

Air systems present particular winter risks as water freezes quickly. Drain air tanks daily if manual, or ensure auto-drains function correctly. Check air dryer cartridge condition and replace proactively before winter. Air leaks force compressors to work overtime, creating moisture that air dryers must handle.
For drivers, DAF recommends carrying essential items including de-icer, scraper, gloves, torch, emergency triangle, hi-vis gear, blanket and basic food and drink supplies.
DAF stresses that DVSA-standard daily walk-around checks become even more critical in winter conditions. A comprehensive check takes minutes but can prevent hours of roadside delays. “Even when stopping for a break, a simple walk around the truck to check tyres and inspect underneath can save you from a roadside breakdown,” advises Mudie. “That one morning when you're in a rush and skip the checks? That’s often when problems that could have been spotted turn into breakdowns.”
Essential daily checks include ensuring all lights function correctly, particularly as today's LED headlights do not generate heat to clear snow or ice. Clean lenses before use. Check that windscreen washers, wipers and heater-demister systems work properly, using winter-grade screen wash. Do not operate wipers when blades are frozen to the screen or when snow has accumulated on the vehicle, as this damages wiper linkages and can blow fuses.
Inspect the AdBlue system regularly; AdBlue freezes at -11°C and most systems stop operating below set temperatures. Check levels, ensure heater elements function correctly, and inspect lines for security.
