Driver behaviour quietly determines whether your fleet is profitable or expensive. Two drivers, same route, same vehicle, can produce a 20% gap in fuel cost and a 5× gap in accident risk. Behaviour monitoring closes that gap.
What to monitor
1. Speeding
Driving above the posted limit or above your company's policy. The single biggest predictor of accident severity.
2. Harsh braking
Frequent harsh-brake events usually indicate either tailgating or distracted driving.
3. Rapid acceleration
Burns fuel faster than steady acceleration and stresses the drivetrain.
4. Sharp cornering
Shifts cargo, wears tyres unevenly, and is uncomfortable for passengers.
5. Excessive idling
A van idling 90 minutes a day burns roughly 3 litres for nothing.
The benefits add up fast
- 25–30% fewer accidents within the first year of monitoring
- 10–15% reduction in fuel spend from smoother driving
- Lower insurance premiums in many policy renewals
- Less brake, tyre, and clutch wear — direct maintenance savings
- More professional service that customers can feel
How to roll it out without losing the team
1. Communicate before you switch on
Tell drivers what is being measured and why. Frame it as safety and fuel — not surveillance.
2. Build a fair scorecard
Combine multiple metrics so a single bad event does not destroy a driver's score.
| Metric | Suggested weight | Sample threshold | |--------|----------------:|-------------------| | Speeding | 25% | <5 events / 100 km | | Harsh braking | 20% | <3 events / 100 km | | Rapid acceleration | 15% | <3 events / 100 km | | Idle time | 15% | <10 minutes / trip | | Seatbelt use | 15% | 100% | | On-time arrivals | 10% | >95% |
3. Coach before you punish
First poor score = conversation. Second = re-training. Third = formal action. Drivers who improve almost always stay improved.
4. Reward the leaders
Public recognition, fuel cards, or a small monthly bonus for the top three drivers does more for behaviour than any number of warnings.
5. Lead by example
If management drives company vehicles, the same scoring rules must apply.
A note on privacy
Always be transparent with drivers about what is tracked, when (working hours only), and why. A clearly written policy prevents misunderstandings and supports your case in any future dispute.
