For many, the first full working week of January marks a return to normal operations.
Fleet vehicles are back on the road, drivers are returning to familiar routes, and schedules begin to fill up again after the festive slowdown.
However, this period also brings a higher risk of vehicle breakdowns, particularly for fleets that have seen reduced use over the Christmas period.
Cold weather combined with long periods of inactivity creates the perfect conditions for avoidable issues, especially with batteries and tyres. These problems often appear just as vehicles are needed most…
Why Batteries Fail And Vehicles Stutter After Christmas And New Year
Modern vehicles continue to draw power even when parked. Alarm systems, immobilisers and onboard electronics all slowly drain the battery. When a vehicle is left unused for several days or weeks, older or weaker batteries can lose enough charge to fail when the engine is started.
Cold temperatures make this worse. Low temperatures reduce a battery’s ability to deliver power, meaning a battery that may have coped in milder weather can struggle during winter.
As drivers return to work and vehicles are restarted after the break, flat batteries are one of the most common causes of early January downtime.
This applies to all vehicle types – petrol, diesel and electric vehicles all rely on a 12-volt battery to power essential systems. Even electric vehicles with sufficient charge in the main battery can be immobilised by a failing auxiliary battery.
The Operational Impact On Fleets
Tyres are another area of concern as fleets restart, with cold air causing tyre pressures to drop, sometimes by a noticeable amount. Vehicles left standing on under-inflated tyres can suffer uneven wear or damage that is only identified once the vehicle is back in daily use.
Low tyre pressures also increase braking distances and reduce grip, particularly on wet or icy roads. For fleet operators, this can affect safety, fuel efficiency and overall running costs.
While a single breakdown may seem minor, the impact across a fleet can be significant. Delayed starts, missed appointments and unplanned maintenance all put pressure on operations during a busy return-to-work period.
Breakdowns also present safety risks. Vehicles stopped at the roadside during winter months are exposed to poor visibility, low temperatures and increased traffic volumes, putting drivers at greater risk.
The start of January is an ideal time to reinforce basic vehicle checks and good habits. Encouraging drivers to report warning lights promptly, ensuring vehicles are driven before returning to full use, and checking tyre pressures and battery health can prevent many issues.
Fleet data can also help identify vehicles that have been inactive for extended periods or are regularly used for short journeys, both of which increase the likelihood of battery problems.
By addressing these risks early, fleets can reduce avoidable downtime, improve driver safety and ensure vehicles are ready for the demands of the year ahead.
