Most insurance companies effectively ignore Parkinson’s as long as they have received confirmation from your neurologist confirming that you are safe to drive. The most important decision is the one you will take yourself or be guided by your wife or family as they will be the first people to tell you that they feel that you should not be driving - and don’t ignore them because the worst thing is to have an accident and have it removed by the courts! It’s a matter of continual self assessment.
