The trade publication has learnt that those in particular hit are drivers over the age of 65, who are required to undertake an annual medical.
31 week wait
According to reports the DVLA are struggling to work their way through a backlog of renewals following the introduction of rigorous controls set up after the refuse truck tragedy in Glasgow back in 2014.
It understood there is currently up to a 31 week wait for a licence renewal following completion of a DVLA medical check.
A spokesman for the DVLA said: “We receive 3,000 medical cases a day and we deal with each as quickly as possible. We have processes in place to prioritise applications from professional drivers whose jobs may be at risk if we are made aware of their circumstances.
“We don’t want to hold on to anyone’s licence longer than necessary. However, in more complex cases we often need additional information from the driver or their doctor. Once this is returned we can make an evidence-based decision.”
