im trying to fully understand the driving licence renewal when you become 70 years old. 

My father in-law currently drives a RAV4 & tows a besacar caravan. I have read that after 70 if you had the b+e on your license you are able to drive a vehicle upto 3.5 tonne in weight  

can any one answer this question   If the combined weight of the whole outfit exceeds 3.5 tonne for the car & caravan would this be classed as over weight thus being illegal even if the tow vehicle is under the weight?
