These Regulations provide for the issue of digital tachograph cards. Such cards are company cards, control cards, driver cards or workshop cards used in connection with digital tachographs. Most drivers of large commercial vehicles are subject to the "EU drivers' hours rules" set out in Commission Regulation (EEC) 3820/85, which limit continuous driving time and require drivers to take minimum breaks and rest periods. This helps to reduce the risks of drivers becoming involved in fatigue-related accidents and thus improves road safety. In order to enforce the drivers' hours rules, it is important to have a record of drivers' activities. Therefore, vehicles subject to the EU drivers' hours rules have to be fitted with a tachograph.
