According to GOV.UK, cars first used before 1 August 1998 do not need to be fitted with a type approved towing bar. However modern cars must meet EU regulations designated for the vehicle you are using.
Experts say drivers can find precise weights in their handbook but urged road users to take caution.
They added “deference” should be taken to match the car’s condition and value as towing could cause damage.
They said: “Your handbook will give you the precise weights of your car (or your car club can help) and many later vehicles may have a max weights plate under the bonnet.
“But bear in mind that despite what the law says, it’s far preferable and safer (especially for towing novices) to stick to the industry’s recommended 85 percent rule (i.e. you only haul up to 85 percent of the car’s kerbweight).
ClassicCars4Sale also warns drivers to determine whether their classic car is “up to the task” of towing at all.
They warn towing a caravan or motorhome can add strain on any car, irrespective of age which could lead to damage
They warn this could affect the “hardest hit compliments” such as the transmission, engine and suspension.
