A blanket ban on diabetes sufferers who use insulin driving public service and heavy goods vehicles has been removed.
Under the new law, people on insulin can now apply to the DVLA to drive larger vehicles such as buses and lorries.
As long as the candidate meets the specific criteria, drivers with insulin-treated diabetes will be able to apply to drive all vehicle categories.
Road safety minister, Mike Penning, said: "We have listened to expert advice and it is clear that treatment and diagnosis has improved since the existing medical standards were put in place, so a blanket ban is no longer needed. These changes strike the right balance in allowing as many people as possible to drive, without compromising road safety."
Last year changes were also made for motor vehicle drivers who suffer from sever hypoglycaemia, in order to meet EU medical standards.
