Wow so much red tape to drive a small motorhome.
I don't know if I have reached the end of the tape, yet. They still might ask for a hospital medical.
These ‘grandfather’ rights, however, are not renewed automatically, so if you wish to retain them after 70, you must ask to do so and will need to provide a medical certificate with the renewal request The medical cost is significant, so many people don't bother to apply. As has become clear, re-applying is a gaff and expensive. So, think carefully before NOT applying!
My medical cost £100 from my GP and lasts for one year to apply. The eyesight test costs nothing. I would agree, think carefully.
There must be hundreds of Oaps driving motorhomes illegally, a mate of mine has just downsized for this very reason.
You are probably right.
