As above. Its VOSA that people need to be worried about, the average copper doesn't know the ins and outs of towing laws. However VOSA are very sharp on towing weights and safety.
As i said earlier in the thread too, just because people have or do tow with them and over long distances it doesn't mean you should. Very few are manufactured to operate the brakes and you can leave plenty of room and try to plan ahead but you can't guarantee that you'll never have to brake in a hurry. The ones mention in this thread i'm interpreting as being intended for motorhomes and as such the brakes operate to prevent the towed car trying to dive under the motorhome when breaking. Theres no doubt about the ability to tow the small car but its a world away from towing a saph with a mundano!

Found this from the NTTA site:
I have a motor home and want to tow a Fiat Seicento behind it using an A-frame. This car has a kerb weight under 750 kg so am I legal with this outfit? Sorry no is the answer. The law regards this as an unbraked trailer and you are allowed to tow up to 750 kg Gross Trailer Weight, not a car’s kerb weight. The figure you have to use is the car’s Gross Vehicle Weight or Maximum Permitted Weight. This is usually at least 300 - 400 kg more than the kerb weight. We have no knowledge of any car sold in the UK that has a GVW under 750 kg. The only vehicle we know that is completely legal to tow with an A-frame is the French Aixam small "car". This is a full four seater and details can be obtained from Aixam UK on 01926 886100. An A-frame or dolly can only be used to recover a broken down vehicle to a place of safety. Transporting a car is, therefore, illegal. A-frames may be offered with a braking system that applies the car's brakes. These do not conform to the law as the car then becomes a "braked trailer" and has to conform to European Directives contained within the Construction and Use Regulations. It does not conform to the European Directive 71/320/EEC and amendments regarding braking requirements in any way. The use of this A-frame for transportation is illegal. It is still OK for use to recover a vehicle to a place of safety.
