Problem: Poor Route Planning Wastes Fuel
When routes aren't well planned, vehicles end up travelling unnecessary distances, leading to higher fuel consumption. In the UK, where fuel costs around £0.55 per mile, inefficient routing can quickly become a costly problem for fleets. The issue gets worse when considering "empty miles" - trips made without carrying any cargo.
Empty miles are a major drain on resources. In 2021, over 20% of the distance covered by cargo trucks across Europe was driven without freight. For UK fleets, even a small reduction - just 1% fewer empty miles per truck - could save over 380 litres of fuel per vehicle annually.
Route deviations add another layer of inefficiency. Without real-time monitoring, drivers may take unscheduled detours, which waste fuel and time. Studies show that 46% of unplanned route changes lead to extra fuel usage. To make up for lost time, drivers often speed, which can increase fuel consumption by as much as 20%. Static route planning also overlooks fuel-intensive manoeuvres, such as left-hand turns in the UK, further driving up costs.
Altogether, these inefficiencies lead to avoidable expenses that telematics technology can significantly reduce.
Solution: Real-Time Route Optimisation
Telematics systems leverage live traffic data and GPS tracking to create more fuel-efficient routes. Unlike static plans that can quickly become outdated, these tools allow fleet managers to adjust routes dynamically, avoiding delays caused by congestion or roadworks. This "eco-routing" approach can cut fuel consumption by 3.3% to 9.3% compared to traditional methods.
The benefits are clear in practice. One large European fleet used detailed route planning to track "Planned vs. Actual Stops" and doubled its order capacity - all without increasing its workforce or extending working hours. Similarly, an electrical product supplier adopted automated routing and tracking systems, reducing unnecessary trips and achieving a 4% drop in fuel costs.
GRS Fleet Telematics offers tools specifically designed to help UK businesses reduce fuel waste. For instance, its geofencing feature establishes virtual boundaries around designated routes, immediately notifying dispatchers if a vehicle strays off course.
The platform also allows fleet managers to compare scheduled stops with real-time GPS data, identifying whether deviations are due to unavoidable traffic issues or preventable driver behaviour. Insights like these help refine routing strategies and cut down on inefficiencies.
"The return on telematics is quite immediate, maybe about a month. Fleet managers could see 15 to 20% savings on their costs." – Juan Cardona, VP Sales, Latin America, Geotab
Additionally, multi-stop routing features ensure vehicles are used more efficiently by reducing empty miles. By bundling loads and seeking backhaul opportunities, some fleets have cut empty miles from 25% to 22%, saving millions of miles overall. On average, this approach reduces 11.4 miles per load, making a noticeable difference in operational costs.
Problem: Driver Habits That Burn Extra Fuel
The way a driver handles a vehicle has a direct impact on fuel consumption. Aggressive driving, which includes rapid acceleration, hard braking, and speeding, pushes the engine to work harder than necessary. For instance, rapid acceleration burns more fuel, while harsh braking wastes the energy that has already been used.
Studies in Europe show that frequent quick acceleration and sudden braking can boost fuel consumption by as much as 40%. Speeding makes things worse: a truck driving at 75 mph uses 27% more fuel compared to one going at 65 mph. For heavy vehicles, every 1 mph increase above 55 mph results in a 0.1 mpg drop in fuel efficiency.
Excessive idling is another common issue. Drivers often leave engines running during breaks, deliveries, or while waiting at depots. However, idling for more than 10 seconds uses more fuel than restarting the engine. In some fleets, idle times can account for 40% to 50% of total engine operation time.
These habits not only waste fuel but also increase wear and tear on vehicles, leading to higher maintenance costs. Without proper insight into driver behaviour, fleet managers may find it challenging to identify who needs guidance or pinpoint areas of inefficiency.
Telematics offers a way to tackle these challenges by providing real-time feedback on driver performance.
Solution: Driver Behaviour Monitoring and Coaching
Telematics systems monitor driving habits in real time, giving fleet managers detailed insights into vehicle operation. By tracking metrics like acceleration, braking, speeding, and idling, these systems generate reports that pinpoint areas for improvement.
The results can be impressive. Scott Logan, Transport Manager at WJ, used telematics data to improve fuel efficiency by 12%, saving the fleet £160,000 overall. This initiative also reduced vehicle breakdowns and the time spent on repairs.
GRS Fleet Telematics provides eco-driving analytics that help businesses in the UK identify and address fuel-wasting habits. Managers can set specific idling limits, such as 30 seconds or less, to cut down on unnecessary fuel use. Some systems even offer in-cab alerts that prompt drivers to turn off the engine if idling exceeds three minutes.
Promoting eco-driving techniques, like smooth acceleration and anticipating traffic to avoid sudden braking, becomes much easier with the help of telematics. Instead of relying on assumptions, managers can provide targeted feedback based on actual data, helping drivers understand how their actions affect both fuel consumption and vehicle health.
Problem: Delayed Maintenance Hurts Fuel Economy
When maintenance is only addressed reactively, small issues like underinflated tyres or clogged filters can linger, quietly sabotaging fuel efficiency. Over time, worn-out components demand more fuel to keep vehicles running. For instance, something as simple as underinflated tyres can significantly reduce fuel economy. Without regular checks, these problems often go unnoticed until they lead to costly breakdowns and emergency repairs.
This approach not only increases repair bills but also affects day-to-day operations. Vehicles running with unresolved issues burn more fuel, reducing miles per gallon and driving up costs. As Teletrac Navman UK aptly puts it:
"A well-maintained truck operates at maximum efficiency, and that includes getting the most out of every drop of petroleum burned".
The absence of real-time diagnostics means fleet managers are stuck with fixed service schedules or delayed alerts, allowing inefficiencies to persist. Shifting to a proactive approach is essential for maintaining fuel-efficient operations.
Solution: Scheduled Maintenance Based on Vehicle Data
Telematics offers a smarter way to manage maintenance by introducing a proactive, data-driven model. These systems use real-time diagnostics and OBD-II data to monitor vehicle health continuously, identifying inefficiencies before they escalate into bigger problems. Instead of sticking to arbitrary service intervals, condition-based maintenance adjusts schedules based on how vehicles are actually used and the wear they experience. Automated alerts notify managers of potential issues - like reaching mileage thresholds or triggering diagnostic codes - helping keep engines in peak condition.
Fleet managers can also automate reminders for routine services and certification checks, ensuring nothing important is overlooked. Pre-trip electronic inspections further enhance efficiency by flagging fuel-draining issues, such as low tyre pressure, before vehicles hit the road. Integrated tyre sensors take this a step further, sending instant alerts for underinflation, which can cut fuel efficiency by up to 10% if left unchecked.
This forward-thinking approach minimises emergency repairs and keeps vehicles running at their best. By tackling problems early, fleets can maintain consistent performance, reduce rolling resistance, and lower overall maintenance costs.
Here’s a comparison to illustrate how telematics-enabled maintenance outshines traditional reactive methods:
| Feature | Telematics-Enabled Maintenance | Traditional Reactive Management |
|---|---|---|
| Scheduling Basis | Real-time diagnostics and actual usage | Fixed intervals or breakdown response |
| Issue Detection | Automated alerts for early wear signs | Driver reports or manual inspections |
| Fuel Impact | Maintains peak MPG through early intervention | Efficiency declines as components wear |
| Cost Profile | Lower planned costs with 5–10% savings | Higher emergency repairs and lost productivity |
Problem: Fuel Theft and Unauthorised Vehicle Use
Fleet managers without proper monitoring tools face a major challenge: fuel theft and unauthorised vehicle use. These issues not only drive up costs but also disrupt the smooth running of operations.
The numbers paint a worrying picture. Reports show a 90% rise in fuel theft incidents in 2022 and a further 77% increase in 2023, with losses accounting for up to 6% of a fleet's total fuel costs. Considering that fuel typically makes up 30–40% of total operating expenses, even minor theft can hit the bottom line hard. Nori Gale from WEX explains the wider impact:
"Fuel theft... not only incurs direct financial losses but also disrupts operations, affecting delivery schedules and client trust."
But theft isn’t the only problem. Unauthorised personal use of fleet vehicles adds to operating costs. Some drivers use company vehicles for personal errands or side jobs, racking up unnecessary mileage and burning fuel without contributing to business revenue [18,20]. Rush Akin, Chief Revenue Officer at RoadFlex, highlights the potential cost:
"A single driver fuelling a personal vehicle just twice a week can cost an agency over £4,000 per year."
For mid-sized fleets, the financial toll can be staggering. If just 10% of drivers misuse fuel cards, annual losses could exceed £50,000. Fraudulent practices like filling "jerry cans" or "buddy fills" further distort fuel data. Studies reveal that 1–3% of all fleet fuel transactions are fraudulent, and this can climb to 3–5% when analysed alongside telematics data.
Solution: Fuel Tracking and Vehicle Security
Telematics offers a powerful way to tackle fuel theft and misuse. By combining real-time monitoring with precise transaction tracking, fleet managers can pinpoint suspicious activity. For example, telematics can cross-check fuel card transactions with GPS data, flagging transactions made when a vehicle isn’t at a fuel pump [17,20]. Alerts for sudden fuel level drops while a vehicle is stationary can indicate siphoning attempts [16,19]. Additionally, transactions exceeding a vehicle's tank capacity can expose "jerry can" or buddy fill fraud [17,18].
Geofencing adds another layer of protection. By setting virtual boundaries around depots or authorised areas, managers receive instant notifications if a vehicle leaves these zones during unauthorised hours. Continuous tracking ensures that unauthorised use is quickly identified, no matter the time.
For fleets facing higher risks, GRS Fleet Telematics offers dual-tracker technology. This includes a primary wired tracker backed by a secondary Bluetooth device. Even if thieves disable the main tracker, the backup ensures the vehicle remains traceable, resulting in a 91% recovery rate within 24 hours. The system also includes remote immobilisation, which allows managers to disable vehicles being used without permission.
Technology alone isn’t enough, though. Clear internal policies are essential to reinforce these measures. Nadia Nyaz from Fleetyr underscores this point:
"The 'I didn't know the fuel card could only be used for the work car' excuse has actually been a winning defence method [in court]... It's up to your internal company policy to outline to employees the rules."
Telematics provides the hard evidence needed to hold employees accountable, while clear policies ensure everyone understands the rules. With prices starting at just £7.99 per month per vehicle, these tools integrate easily into existing operations, turning fuel data into actionable insights that safeguard both assets and budgets.
