What is a Tachograph?

For those that are new commercial van owners or lorry drivers then you may not have heard of a tachograph before, in this article I will explain exactly how the device works and its purpose within the van and truck world.

Firstly, a tachograph is a device that is fitted to vehicles to record their vehicles speed over time. This is mainly installed in lorries and other large vehicles. A tachograph is commonly installed behind a vehicles speedometer and uses a stylus to record the vehicles information by means of a line that is drawn upon a moving paper disk. This paper disk is set out so that it does a full rotation during the space of twenty four hours. These types of device are very easily tampered with and as such are being replaced by a digital meter that is not only more secure but also much more reliable and precise.

Depending on your location within the world it may be mandatory to have a tachograph installed in your vehicle if it is used for commercial use, and you can be asked to make it available for inspection at anytime by any governing or policing bodies.

There are numerous reasons that a tachograph could be required in a van such as a Ford Transit Connect, rules such as restrictions on working hours whilst driving is one of the most important.

In some instances these devices are examined using a microscope should an accident involving the vehicle take place and can be of notable help to authorities when checking events prior to a collision.

Within the UK there are rules and regulations regarding driving hours, these are quite complicated and anyone with any questions regarding this are advised to contact the proper authorities such as VOSA and the Department for Transport.
