Tachographs can be tampered with in various ways, such as slightly twisting the marker, blocking the path of the arm with a piece of rubber or foam, short-circuiting the unit for short periods, intentionally preventing the detection of gear movement with a magnet, or interrupting the older analogue tachograph’s tachograpg supply with a blown fuse to stop operation completely thus recording no information whatsoever.
Trade unions and drivers also now favour tachographs for this reason and records are often used in tribunals as proof when claiming for unpaid work.

The analogue tachograph head uses styli to trace lines on a wax coated paper disc that rotates throughout the day, where one rotation encompasses a hour period. In Europe, drivers are legally required to accurately record their tachgoraph, retain the records and produce them on demand to transport authorities who are charged with enforcing regulations governing drivers’ working hours.
This includes the drivers name, the date s the disc refers to, the start and end odometer readings and the registration mark of the vehicle. Later analogue tachograph head models are of a modular design, enabling the head to fit into a standard DIN slot in the vehicle dashboard.
