May be of help to someone here. Involves towing restrictions with a 3.5 tonne truck. After buying a truck with a tacho fitted I decided to confrim a few points I had been told from different sources. Dont quote me on this but this is what I ended up with.
Tachograph in a 3.5 tonne gross vehicle
=========================================
If a tachograph is fitted in a 3.5 tonne gross vehicle it does not have to be used unless you are towing a trailer. Even then it may still not have to be used. (See Below)
Towing a trailer for business use with a 3.5 tonne gross vehicle
=================================================================
Tachgraph will have to be used unless ALL four rules apply below
Four rules to abide by:
1. Total combined weight does not exceed 7.5 tonne (Check legal train weight for truck)
2. Stay in a 50km (31.6 miles) radius of home base of vehicle.
3. for carrying materials, equipment or machinery for the driver’s use in the course of his work.
4. on the condition that driving the vehicle does not constitute the driver’s main activity.
If the trailer unloaded weighs more than 1,020 KGs an operaters licence will be required. (see below).
The following taken from VOSA website PDF file
(Rules on Drivers’ Hours and Tachographs Goods vehicles in the UK and Europe)
Exemptions and derogations
---------------------------
Vehicles or combinations of vehicles with a maximum
permissible mass not exceeding 7.5 tonnes that are
used:
• for carrying materials, equipment or machinery
for the driver’s use in the course of his work.
These vehicles shall be used only within a 50 km
radius of the base of the undertaking and on the
condition that driving the vehicle does not constitute
the driver’s main activity.
==================================================================================
Operaters Licence
=========================================================
No operaters licence will be needed if the trailer has an unladen weight of less than 1,020 KGs
The following taken from the transport office website (Vehicles outside Operator Licence Requirements)
It is also worth knowing that, when towing a trailer behind a vehicle that is around - or slightly below - 3.5 tonnes gross plated weight (e.g Ford Transit/Mercedes Sprinter sized vehicles), if the combined gross plated weights of drawing vehicle and trailer do not exceed 3.5 tonnes or (where there is no gross plated weight) the total unladen weights do not exceed 1,525 kgs, an operators licence will not be required. Please note that any trailer with an unladen weight of less than 1,020 KGs, need not be taken in to account in this calculation.
