My OH kept his license, with the support of our neurologist, for 17 years, although he didn't drive far or often.They still had the knowledge they they could drive.
Then, a form from the DVLA, filled in by a locum GP at our surgery, (when renewal was due),.a doctor that my OH had never seen, but which stated that, he HAD seen him on a certain date, (that date was a letter from the neurologist to the surgery),with no indications that OH was not fit to drive, BUT the locum obviously didn't read it correctly/fully, and said that meds. had been increased, they hadn't, just dosage split but the same amount, and a great deal more that was inaccurate. That resulted in their driving license being revoked.
We challenged it and the locum wrote to the DVLA explaing his error. Error is too polite word as to how it destroyed my OH' s self esteem. I wish that I had taken it further than the surgery's manager, who I had to had to contact twice to even receive a reply and then it it was waffle. That GP should have been referred to the GMC for gross misconduct.I wish I had done so.
