Read the first 6 Tachograph Rules & Drivers' Hours flashcards as text

  1. What is a 'Smart' (second generation) tachograph's main additional feature compared to older digital tachographs?

    Answer: It communicates remotely and uses GNSS (GPS) to record location data

    Second generation (Smart) tachographs use GNSS (global navigation satellite system) for location recording and can communicate remotely via DSRC (Dedicated Short Range Communications). They record location data at the start and end of each journey.

  2. When a driver takes a 45-minute break, can they split it?

    Answer: Yes: first 15 minutes then 30 minutes, in that order only

    The 45-minute break can be split into two parts: the first must be at least 15 minutes and the second must be at least 30 minutes, and they must be taken in that order. The order cannot be reversed.

  3. What does a tachograph symbol showing a bed mean on the mode selector?

    Answer: Rest or sleep period

    The bed symbol on a tachograph mode selector indicates that the driver is taking a rest or sleep period. This is distinct from the break mode and is used for daily and weekly rest periods.

  4. An enforcement officer asks to see a driver's tachograph records. The driver must produce records for:

    Answer: The current day and the previous 28 days on the card

    When requested by an enforcement officer, a driver must be able to produce their driver card (which stores 28 days of data) and any manual records or printouts. The officer can examine records stored on the card.

  5. What must a driver do when they change from driving one vehicle to driving another vehicle on the same day?

    Answer: Record the vehicle registration of both vehicles on a manual printout

    The driver card belongs to the driver and must be inserted into the tachograph of every vehicle they drive. The card records all driving regardless of which vehicle is used.

  6. What is the penalty category for a 'most serious' tachograph offence in the UK?

    Answer: An immediate prohibition and potential prosecution

    The most serious tachograph and drivers' hours offences can result in an immediate prohibition on the driver and vehicle, followed by prosecution in the magistrates' court, with potentially unlimited fines.
