Thanks to fleet management with GPS devices, it is possible to measure and report certain data that reflects the behavior of the operator towards the vehicle. For example, average speed, unauthorized stops, fuel level, vehicle temperature, and more.
Without the technology, managing the use of fuel would not be impossible, but it would be very inefficient, because you would not have high-precision and remote-measurement devices in real time.
As a practical example, consider that traveling at speeds greater than 90 miles/h consumes at least 20% more than those less than 80 miles/ h. Luckily, if you have fleet management with GPS, you will be able to instantly determine if a driver exceeds the speed limit established in company policies, and you will be able to better control these behaviors.
