If you passed a driving test in 1958 and drive a motorhome at 3.5 ton, what type/weight of trailer are you/can you tow, if any. Meaning that if you tow any trailer is that allowed? I know you a restricted on weight if you passed you test after 1997 (I think ) but before that date, what are the rules. I know that you can - at the age of 70 plus- take a medical and drive over 3.5, but that means HAVING to pass a medical every 2 years. But what if you drive at 3.5 ton and then pull a trailer of say 1 ton.
