Fuel-Efficient Driving Techniques for HGV Professionals
Fuel is typically the largest single operating cost for any haulier, often accounting for 30 to 40% of total running costs. A 44-tonne artic averaging 8 miles per gallon at diesel prices of £1.50 per litre spends roughly £700 to £900 per week on fuel. Even small improvements in driving style can save significant money — and many employers actively monitor and reward fuel-efficient drivers.
Progressive Shifting
Modern HGV engines produce maximum torque at relatively low revs — typically 1,100 to 1,400 RPM. The most fuel-efficient technique is to shift up early and let the engine work in its torque band rather than revving high. Block shifting (skipping gears, such as going from 4th to 6th) is perfectly acceptable and saves fuel.
Anticipation and Momentum
The golden rule of fuel-efficient driving is keep the truck moving. Every time you brake, you waste the energy used to reach that speed. Read the road ahead:
- Ease off the accelerator early when approaching roundabouts, junctions, or traffic
- Maintain a safe following distance so you can adjust speed gradually
- Use engine braking on downhill sections rather than the service brake
- Time traffic lights where possible to avoid a complete stop
Cruise Control
Use cruise control on motorways and dual carriageways to maintain a steady speed. Constant speed is more efficient than repeatedly speeding up and slowing down. However, switch it off on hilly terrain — cruise control tends to over-fuel going uphill and waste momentum going downhill.
Tyre Pressures
Under-inflated tyres increase rolling resistance and fuel consumption significantly. A tyre that is 15% under-inflated can increase fuel consumption by 2 to 3%. Check pressures regularly when tyres are cold. Correctly inflated tyres also last longer and handle better.
Idle Reduction
An idling HGV engine burns approximately 1 to 2 litres of diesel per hour. If you are stopped for more than a couple of minutes and it is safe to do so, switch off. Many modern trucks have auxiliary heaters and cab comfort systems that run without the main engine.
SAFED Training
SAFED (Safe and Fuel Efficient Driving) is a structured training programme that counts towards your Driver CPC hours. It covers all the techniques above in a practical, on-road setting. Many drivers report fuel savings of 5 to 15% after completing SAFED training.
How It Affects Your Agency Score
Many logistics companies track driver fuel performance through telematics. If you work via an agency, your fuel efficiency, harsh braking events, and idling time are often reported back. Drivers with consistently good scores get first pick of the best shifts and routes. Poor scores can result in being de-preferred by clients. Driving efficiently is not just about saving the planet — it directly protects your income.
