D4 Medical Assessment form
Some doctors will be able to fill in both the vision and medical assessment sections of the report. If your doctor is unable to fully answer all the questions on the vision assessment, you must have it filled in by an optician or optometrist.
As of 20 June 2019, DVLA no longer accepts medical applications (D4) completed by Doctors on Wheels Ltd.
