Fuel is one of transport companies’ biggest expenses. Even small changes in truck driving can have a major impact on monthly costs. That’s why more companies are turning to driver behaviour monitoring and personalised driver coaching.

A recent case in Finland shows just how much difference this can make. Thanks to Mapon solutions, just one driver was able to save €1,000 on fuel costs per month. Your fleet can achieve the same or even better results. Read on to learn how to do it.

A new driver, a clear plan

When a new truck driver joined one of our Finnish client’s’ fleet, the company decided to track performance from the start. They didn’t just want to see how the driver handled the vehicle – they wanted to make fuel efficiency part of the daily routine.

In the first weeks, they closely monitored fuel consumption, idling, and use of eco speed. These insights became the base for a two-week personalised eco-driving training program.

Before training: Higher fuel use, more idling, and less eco speed. Driver score: C.

Training that changes habits

The training wasn’t just a classroom lecture. It combined real data with real-time feedback.

  • After each trip, the driver received a report showing exactly where improvements were needed.
  • The fleet manager coached directly, pointing out moments of excessive idling, speeding, or missed opportunities to use cruise control.
  • Progress was tracked week by week, so the driver could see the difference for themselves.

This made the learning process easy and specific. The driver wasn’t just told what to do differently – they could see the effect of their actions on the numbers.

After training: Fuel use dropped, idling fell, eco speed and cruise control improved. Driver score: B.

The results after one month

The impact of driver behaviour monitoring became visible quickly:

  • Fuel use dropped by 5.2 L per 100 km.
  • Eco speed and cruise control were used more often, reducing unnecessary fuel burn.
  • Idling times decreased, saving even more fuel.

For a single driver, these changes may seem small at first. But when you add up the kilometres, the savings tell a bigger story.

Big savings from small changes: €1,000/month per driver, €20,000+ for a 20-truck fleet.

What the numbers mean

This driver covers around 3,000 km every week. With fuel costing around €1.80 per litre in Finland, the improvements translate into more than €1,000 saved every month.

Scale that to a fleet of 20 trucks, and you’re looking at savings of more than €20,000 each month.

Over a year, that’s close to a quarter of a million euros.

And the benefit doesn’t stop with money. Lower fuel use also means fewer emissions, helping the company meet sustainability targets.

Why monitoring makes the difference

Technology plays an important role here. Tracking driver behaviour on the Mapon fleet management platform gives managers data, not just assumptions. It shows where fuel is wasted and highlights good habits that should be encouraged.

But data alone doesn’t change behaviour. Without regular feedback, many drivers slip back into old routines. That’s why our client combined monitoring with coaching and consistent follow-up.

It’s the combination of clear data and ongoing guidance that makes positive results stick.

Practical eco-driving tips for fleets

Companies don’t need to wait for a full program to start seeing results. Here are practices any driver can apply right away:

  1. Reduce idling: turn off the engine if the stop will last longer than a minute. Even short idle times add up over a month.
  2. Use cruise control: on highways, cruise control helps maintain steady speed and cuts fuel use.
  3. Stick to eco speed: driving just 5–10 km/h slower on long stretches can reduce consumption without major delays.
  4. Anticipate traffic: look ahead, brake less, and coast when possible instead of accelerating hard.
  5. Check tyre pressure: under-inflated tyres increase rolling resistance and fuel burn.

Small improvements in these areas can add up quickly across a fleet.

Lessons for you

This case shows that meaningful savings don’t always require new vehicles or expensive technology. Sometimes the biggest gains come from how existing trucks are driven.

For any transport company, the key steps are:

  1. Monitor driver behaviour to understand current habits.
  2. Train drivers with data-driven feedback instead of generic advice.
  3. Provide ongoing coaching to prevent slipping back into wasteful habits.
  4. Track progress over time to see results and keep motivation high.

Mapon ensures long-term impact

Fuel efficiency isn’t just a cost issue. It’s also about staying competitive and complying with ever-tightening sustainability regulations.

For our Finnish client, it started with one driver and one training program. The results speak for themselves, and the same approach can be scaled to the whole fleet.

If your company wants to achieve the same, Mapon can help with the tools and insights to track progress and keep improvements on track. Reach out to learn how smart driver behaviour monitoring could work for your fleet!
