Doctors lack the training required to assess patients' fitness to drive, according to research.
Researchers from Warwick University found doctors received little tuition on how certain medical conditions, like diabetes or dementia, affect fitness to drive.
Although most health professionals are aware of DVLA guidelines on fitness to drive, many are unable to distinguish reliably between medically unfit drivers, borderline drivers and fit drivers, research found.
For the research, undertaken for the Department for Transport, 1,519 health professionals, 358 patients and 55 medical school personnel were interviewed.
The MIMS summary of the DVLA guidance on medical standards of fitness to drive is now online.
