from a trafic cop point of view, weight he is interested in as below is the laden weight, he will take you to the weighbridge if he feels unit looks unsafe.
is the ifor williams website is refering to comercial vehicles, not plg, as all cars and 4x4 are.
we have 4 of there trailers i can ask them.
you cant exceed maximum train weight, you cant exceed maximum towing weight.
but even that said, if they feel the driver is not safe with load, no matter how heavy they will take action.
was this thread not meant to be lr bashing?
got off track
Department for Transport guide to legal requirements for trailers and towing
Statement
Requirements regarding trailers used on the road are given in the Road Vehicles (Construction and Use) Regulations 1986, as amended (C&U) and the Road Vehicles Lighting Regulations 1989, as amended (RVLR). The following is a summary of the main requirements.
1 Weight
In the case of light trailers, that are less than 3500kg in maximum laden weight, there is not any specified relationship in UK law between the weight of the towing vehicle and the weight of the trailer.
For M1 category vehicles (motor vehicles used for the carriage of passengers and comprising not more than eight seats in addition to the driver's seat) the maximum permissible trailer weight is quoted by the vehicle manufacturer. If this is exceeded it is possible that the Courts or Insurance Companies may take the view that this constitutes a danger.
The maximum laden weight of a trailer, which may be towed by a light goods vehicle depends on both:
■the stated gross train weight of the towing vehicle (GTW) and
■the vehicle manufacturer's recommended maximum permissible trailer weight.
Neither the maximum permissible trailer weight nor the maximum gross train weight (the laden weight of the trailer plus the laden weight of the towing vehicle) should be exceeded.
It is possible that the stated gross train weight is less than the sum of the stated maximum permissible laden weight of the towing vehicle and the stated maximum permissible laden trailer weight. In this case the towing vehicle and the trailer must be loaded such that each does not exceed its individual maximum limit and the sum of both does not exceed the maximum gross train weight.
It is not a requirement to display a notice of the unladen weight of the trailer or the towing vehicle, unless the towing vehicle is either a motor tractor or a locomotive, as defined in the C&U.
If the towing vehicle has a permissible gross weight in excess of 3.5 tonnes the maximum width and length of the trailer are 2.55 metres and 12 metres respectively. If, however, the gross weight of the towing vehicle is 3.5 tonnes or less, then the maximum permissible width and length are 2.3 metres and 7 metres respectively. In both cases, the overall length of the towing vehicle and trailer must not exceed either 18m or 18.75m depending on the type of towing vehicle.
The definition in C&U of the overall length of a trailer makes it clear that the coupling device and draw-bar are not included in the length dimension. In the case of a caravan, where a protective box is mounted on to the front, which is supported on the draw-bar for the purpose of storage gas tanks, for example, this box is included in the overall length.
These requirements also apply to visiting vehicles. Under Regulation 4(4) Item 2 of C&U, we permit a vehicle to be brought into Great Britian by a person resident abroad, provided that the vehicle complies in every respect with the requirements relating to motor vehicles or trailers contained in:
Braking requirements are prescribed in Regulations 15 and 16 of The Road Vehicles (Construction &Use) Regulations 1986 as amended.
■A trailer with a maximum design laden weight of more than 750 kg must be braked.
■An inertia (overrun) type braking system may be used up to a maximum permissible laden weight of 3500kg.
■It is not permitted to use an unbraked trailer, the laden weight of which exceeds 50% of the kerbside weight of the towing vehicle.
■For trailers up to 1500kg laden weight, it is permitted to use secondary coupling, which in the event of separation (NOT failure) of the main coupling, will retain the trailer attached to the towing vehicle, prevent the nose of the trailer from touching the ground and provide some residual steering of the trailer.
■Above 1500 kg laden weight, the trailer must be fitted with a device to stop the trailer automatically in the event of separation (NOT failure) of the main coupling. This is normally achieved by a breakaway cable attached to the parking brake mechanism where the trailer becomes detached from the towing vehicle.
