Since the new digital tachograph was introduced, onboard sensors monitor data such as vehicle position, speed and direction. Tachograph data detects if a tachograph card is present, and records the time when a driver begins and ends a driving shift pattern.

Fleet managers can monitor tachograph data to ensure jobs are being performed correctly. Identifying which driver is driving which vehicle and how long they drive for, how fast they go and which direction they head in. All of this is vital in running a smooth operation, and any strays outside of the permitted session can be flagged up to fleet management operators.

It can also be used to work out variances across different drivers. Some drivers may operate more efficiently, drive smoother and can be rewarded for greater output. Where other drivers can be offered advice on how to improve their tachograph data and productivity.
