From March 2015 farmers no longer need a tachograph fitted to their vehicles if the distance travelled is less than 100km from their operating base. Before March this distance was 50km. The base is defined as where the vehicle starts off that morning, following an 11-hour driver rest period. The new 100km exemption will apply to vehicles or vehicle-and-trailer combinations with a maximum weight of 7,500kg being used to carry materials, equipment or machinery for the driver’s use in a farming capacity, as well as vehicles used to carry live animals to and from local markets and slaughterhouses. Vehicles will no longer have to be fitted with tachograph reading equipment and drivers will no longer have to comply with EC drivers’ hour rules, instead falling under GB domestic drivers’ rules.
