Winter driving presents unique and serious challenges for HGV drivers. Ice, snow, reduced visibility, and wet roads all dramatically increase stopping distances and the risk of losing control of a large, heavy vehicle. An articulated lorry travelling at 60 mph on a dry road requires approximately 96 metres to stop; on ice, that distance can increase to 600 metres or more. This comprehensive guide covers the essential techniques, legal requirements, and practical preparations that HGV drivers need to stay safe during the winter months in 2026.

Why Winter Is Particularly Dangerous for HGV Drivers

HGVs are more vulnerable to winter conditions than cars for several reasons. Their greater mass means they take much longer to stop and are harder to control in a skid. Their high centre of gravity makes them more susceptible to rollover, particularly on bends and slip roads. Their large flat sides act as sails in crosswinds, which are more common during winter storms. Articulated lorries can jackknife if the trailer brakes lock before the tractor unit brakes. And the cab's elevated position means the driver may not feel the road surface conditions as clearly as a car driver.

Pre-Journey Preparation in Winter

Vehicle Check

Before setting off in winter conditions, complete a thorough walkaround check with particular attention to:

• Tyres: Check tread depth (minimum 1 mm, but 3 mm is recommended for winter driving), tyre pressure (cold pressure should be correct — tyres lose approximately 1 psi for every 10°F drop in temperature), and tyre condition. Consider winter tyres if operating in areas with regular snowfall.
• Brakes: Check air pressure and listen for leaks. Ensure the trailer brake system is functioning correctly.
• Lights: All lights must be clean and working. Winter conditions reduce visibility significantly, making lights even more important.
• Windscreen and mirrors: Clear all ice and snow from the windscreen, all windows, mirrors, lights, number plates, and the roof of the cab before setting off. Driving with an obscured windscreen is a criminal offence.
• Windscreen washer fluid: Use a winter-grade screen wash that will not freeze in the reservoir or on the windscreen. Top up before setting off.
• Fuel: Keep the fuel tank at least half full in winter. Diesel can gel in very cold temperatures — use winter-grade diesel or add a diesel anti-gel additive if temperatures are forecast to drop below -10°C.

Route Planning

Check weather forecasts and road condition reports before setting off. The Met Office and the Highways Agency's Traffic England website provide up-to-date information on road conditions, closures, and weather warnings. Plan an alternative route in case your primary route becomes impassable. Allow extra time for your journey — do not put yourself under pressure to maintain normal journey times in adverse conditions.

Emergency Kit

Carry an emergency kit in the cab during winter, including a shovel, a bag of sand or grit, traction mats, a torch, warm clothing and blankets, food and water, a first aid kit, a warning triangle, and a fully charged mobile phone. If you become stuck in snow, these items could be essential.

Driving Techniques in Winter Conditions

Ice and Snow

On ice or snow, the key principles are to drive smoothly and gently, avoid sudden inputs, and maintain much greater following distances than normal. Specific techniques include:

• Reduce speed significantly: On snow or ice, reduce your speed to well below the speed limit. There is no safe speed on ice — even 20 mph can be too fast to stop in time if a hazard appears.
• Increase following distance: Leave at least 10 times the normal following distance on ice. On a motorway in normal conditions, the two-second rule gives approximately 55 metres at 60 mph. On ice, allow at least 550 metres.
• Brake gently and early: Apply the brakes gently and progressively. Avoid sudden braking, which can lock the wheels and cause a skid or jackknife. Begin braking much earlier than normal for junctions, roundabouts, and bends.
• Use engine braking: Change down through the gears to use engine braking before applying the service brake. This reduces the risk of wheel lock.
• Avoid sudden steering inputs: Steer smoothly and gently. Sudden steering movements on ice can cause the vehicle to slide or the trailer to swing.
• Use ABS correctly: If your vehicle has ABS, apply firm, continuous pressure to the brake pedal — do not pump the brakes. ABS will modulate brake pressure automatically to prevent wheel lock.

Skid Recovery

If the tractor unit begins to skid, ease off the accelerator and steer gently in the direction you want to go. Do not apply the brakes. If the trailer begins to swing (jackknife), ease off the brakes immediately and steer to correct the tractor unit. Jackknife recovery is extremely difficult at speed — prevention through smooth driving is far more effective than attempting recovery.

Fog

In fog, reduce speed and use dipped headlights and rear fog lights when visibility falls below 100 metres. Do not use full beam — it reflects off the fog and reduces visibility further. Maintain a safe following distance and be prepared to stop. Do not assume the road ahead is clear because you cannot see any hazards. Switch off the rear fog light when visibility improves to avoid dazzling following drivers.

Crosswinds

HGVs are particularly vulnerable to crosswinds due to their large, flat sides. In strong crosswinds, reduce speed and be prepared for sudden gusts, particularly when emerging from sheltered areas (cuttings, bridges, buildings) onto exposed sections of road. Be especially careful when overtaking or being overtaken by other large vehicles, as the aerodynamic interaction can cause sudden steering inputs.

Flooding

Never attempt to drive through floodwater of unknown depth. Water as shallow as 30 cm can cause loss of control of an HGV. If you must drive through shallow floodwater, drive slowly (no more than 5 mph) in first gear, maintain a steady engine speed, and test your brakes as soon as you emerge from the water. Do not attempt to drive through water that is flowing rapidly or that is deeper than the bottom of the vehicle's doors.

Legal Requirements in Winter

There are no specific UK laws requiring winter tyres on HGVs, but drivers have a legal duty to drive in a manner appropriate to the conditions. Driving too fast for the conditions — even if below the speed limit — can result in prosecution for dangerous driving if an accident occurs. The Highway Code states that you should reduce speed in adverse weather conditions and increase following distances.

Clearing ice and snow from the vehicle before setting off is a legal requirement. Driving with an obscured windscreen is an offence under the Road Vehicles (Construction and Use) Regulations 1986. Driving with snow on the roof of the cab is not explicitly illegal but can result in prosecution if the snow falls and causes an accident or obstruction.

Tachograph and Drivers' Hours in Winter

Winter conditions can significantly extend journey times. Under drivers' hours rules, you must not drive beyond your legal driving time limit, regardless of the conditions. If adverse weather means you cannot reach your destination within your legal hours, you must stop and take a rest period. Plan your journey to allow for delays, and communicate with your transport manager if conditions are causing significant delays. The tachograph will record your driving time accurately — do not be tempted to continue driving beyond your legal limit to meet a delivery deadline.

Winter Driving and Driver CPC

Advanced driving techniques for adverse weather conditions are covered in Driver CPC periodic training. If you have not recently completed a CPC module on defensive driving or hazard perception, consider booking one before the winter season. These modules cover skid avoidance, emergency braking, and route planning in adverse conditions, and can significantly improve your confidence and competence in winter driving.
