If you drive an LGV or PCV you must follow the rules on how many hours you can drive and the breaks you need to take. These rules are designed to keep you, your passengers and other road users safe by reducing the number of accidents caused by drivers falling asleep at the wheel. See the rules on drivers’ hours on GOV.UK.
Although there are analogue tachographs in older vehicles, all vehicles registered since 1 May 2006 must be fitted with a digital tachograph. If you’re a vehicle operator you can download data from the digital tachographs in your vehicles using a smart card. Apply for a digital tachograph company smart card at GOV.UK.
