Thanks for your story and input with regards to the DVLA It does look like we have to jump through many hoops but guess safely is paramount.
Husband doesn’t want to drive at the moment, very low, trying Sinemet and only hope this will helps.
Luckily the car is automatic and guess the mirrors would help with stiffness/vision although neither a problem at the moment. Insurance is due soon and as he is not driving we have decided to wait until we hear back from the DVLA.
I will bare in-mind your tips!
Best wishes and thanks.
