Some info taken from BRINK towbars website. Laws and regulations If you have a towbar installed on your car, several legal rules and requirements are in effect. If you are driving with a trailer, caravan, boat trailer or horsebox attached, there are many rules to follow at home and abroad as well. MOT test During the MOT test, your towbar construction is checked as well. Your towbar ball should not be too worn and the locking mechanism should function properly for a detachable towbar. In addition, three important requirements are checked. Type test The towbar has to have a type test. This is listed on the type plate of your towbar. If the type plate is missing, you may only tow a trailer that weighs less than 750 kg, load included. In addition, your trailer including load should not weigh more than the total weight of the towing car. Wet en regelgeving Indicators When towing a trailer, your car should have indicators on the side. Towbar and Nose Weight The weight with which the coupling of your trailer, caravan, boat trailer or horsebox pushes down on the towbar, should not exceed the limit set by the towbar manufacturer. This value is listed on the type plate of your towbar. In addition, check the Hand Book of your car and the towed vehicle, as other values might be listed there. The basic principle is that the lowest value determines the maximum weight, which you should never be exceeded. Visible license plate It is not allowed for the towbar to (partially) cover your car’s license plate. If the plate is covered or partially covered, you need to move the license plate and adjust the license plate lights. A towbar with detachable ball could be an alternative. Changes The rules and regulations with regard to towbars and trailers are subject to change. We recommend regularly checking the DVSA website in order to stay abreast of the latest applicable rules and regulations.
