2. Tachographs in light vehicles
If you use a smaller vehicle (eg a 4x4) for towing, you’ll only need a tachograph if its total weight is more than 3.5 tonnes.
Fitting a tachograph
Read the Driver and Vehicle Standards Agency (DVSA) guidance on where you can fit a tachograph unit in a vehicle.
Buying or leasing a vehicle
If you buy or lease a vehicle and it comes under the EU or AETR rules on drivers’ hours you’ll need to make sure it’s designed to have a tachograph fitted.
Phone DVSA if you’ve already bought a vehicle and are having problems fitting it with a tachograph. They can tell you where your nearest Approved Tachograph Centre is.
The Tachograph Centre can give you advice and help you get it fitted. It’s not always possible to fit a tachograph, however.
