With the scrapping of the towing test we shouldn’t be lulled into thinking that we can just hitch up and go. If you have never towed before there is a lot to learn and understand before you do. The law regarding towing has changed and now you can tow legally with a vehicle with a gross weight of up to 3.5 tonnes (not including minibuses) without the need to take a further test.
What should you do? you really should seek training, in the New Year there will be a new accredited towing course launched by the DVSA and other parties. In the meantime follow the Government’s recommendations and have training with a qualified trainer who will steer you through the safety and manoeuvring elements and train you on how to tow safely on the road.
