HM Senior Coroner for Lancashire Dr James Adeley:

"The current system for 'ensuring' drivers meet the visual legal standards is ineffective, unsafe and unfit to meet the needs of society as evidenced by the deaths of Marie Cunningham, Grace Foulds, Anne Ferguson and Peter Westwell where the DVLA continued to provide licences to drivers who had failed to meet the legal sight requirements."

Terry Wilcox, of Hudgell Solicitors, representing the families of Mrs Cunningham, Mrs Foulds and Mr Westwell, said loop holes that are available for drivers who want to evade reporting on their eyesight are "jaw-dropping".

Rob Heard, chairman of the Older Drivers' Forum, warned that more people would die if changes were not made soon.
