Having done a bit of research recently on the legalities of trailing in South Africa I thought I try and write something about it. First off it seems that almost no-one knows the law. Trailer makers don’t even have a clue. Car manufacturers tell you how much you can trail but this doesn’t mean it’s legal… There are numerous stories in the forums, particularly fishing forums, of people being escorted to weigh bridges and having to leave everything on the side of the road and pay huge fines. Besides this, think of the insurance angle…you are happily towing your overweight boat behind your discovery 3 and have an accident… You’ve written off the car in front, your own vehicle and the boat. Time to call the insurance companies, but hang-on you were towing illegally – guess who gets to pay the bill!! The risks of towing illegally are huge..
