A tachograph is a round instrument on a taxi or a truck dashboard, which looks like a clock. There is a roll of recording paper inside, and every motion of a vehicle with a tachograph is recorded, such as starting, traveling, hitting the brakes, and stopping. A computerized version of the tachograph is the driving monitoring system.

It can show information about when a vehicle starts and stops, how it travels, where is goes for delivery, and how long it takes to unload its cargo. This system records not only a vehicle's travel condition, but also the driver's work condition, in a memory card. The drivers of delivery companies used to write down all such information in a daily operation report, but it has become as easy as using a pocket calculator, thanks to this system.

By monitoring how a vehicle drives, it is possible to cut out unnecessary expenses and to ensure safe driving. For example, too many sudden accelerations or stops are not only considered dangerous but also a cause of fuel inefficiency. The companies and the drivers pay attention to these incidents after examining traveling data. Additionally, it is easy to calculate salaries using data in a memory card, which contains all the information for how much work was done by drivers in one day.

With the help of the driving monitoring system, companies are making efforts for safe driving and reliable delivery.
