Drivers are supposed to tell the DVLA if they have a medical condition which would disqualify them from holding a licence.
However, some police forces have reported as many as 30 percent of over 70s with medical conditions fail to inform the DVLA of the issue.
Department for Transport data has also revealed over 70s are more likely to be involved in driver error collisions.
“It’s a way of getting out and communicating with others, it stops them feeling isolated and alone.
“There’s plenty of capable 70-year-old drivers, it’s not everybody, but at the moment the checks and the law aren’t strong enough.”
