Any time you intend to use your company's vehicle to tow a caravan or any trailer, you need to study and understand all the laws that apply. It is important to consult your fleet manager to guide you about the requirement of your display trailers. The laws governing over towing trailers are categorized as discussed below
Specific Trailer Restrictions
If the vehicle you are using to tow is not equipped with air brakes system that can be connected to your trailer, then the heaviest trailer that can be allowed on UK roads is utmost 3500kg GVW (gross vehicle weight). This means that it must have a maximum width of 2.55m and a length of seven meters. This length excludes the drawbar and coupling. If the towing vehicle weighs more than 3500kg gross vehicle weight, then it needs to have a maximum width of 2.55m, a length of 12m, a total length of vehicle and trailer of 18m, a minimum of four wheels and the overhang of load from the rear of the trailer should be utmost 3.05m. It is advisable to check the VIN plate on the chasis and the vehicle's handbook for the manufacturer's recommendedsuggested towing weight limit.
The Maximum Weight That the Trailer Should Carry
This depends on whether or not your trailer has brakes. If the trailer in unbraked, it should carry a weight of utmost 750kg. Generally, the plated GVW (gross vehicle weight) of any unbraked trailer should be less than half the overall kerb weight of the vehicle that is being used to tow it. For braked trailers with overrun brakes can carry a weight of utmost 3500kg gross trailer weight. You are not to exceed your trailers Gross Train Weight. The maximum theoretically-possible weight of any trailer that can be legally towed is equal to Gross Train Weight minus the weight of your towing vehicle (this includes fuel, passengers, driver, and cargo).
Only trailers with legal number plates that are manufactured by a number plate manufacturer that is licensed are allowed on the road.
Apart from meeting the trailer's weight specification, this load needs to be tied down securely, evenly distributed, and try to avoid load projections. This increases the safety of the trailer.
Lighting for Trailers
Each trailer should have a number plate light, two triangular red reflectors, two red stop lights, two red sidelights, and amber indicators (they should flash between 60-120 times every minute) at the rear. If the trailer is more than 1.3m wide, it must have a fog lamp mounted either to the right of center or the centre of the towing vehicle. If the trailer's width is more than 1.6m it should have front position lights and if it is less, then it need front reflectors.
When on dual carriageways and motorways, the speed limit for trailers should not exceed 60mph. The speed limit on any other road is 50mph. Trailers should not be on the outside lane of any motorways.
Ensure that your trailer has been fitted with a 50mm ball coupling to BSI and ISO standards
