A shortage of driving examiners has seen learners waiting more than twice as long as they should.
The Driver and Vehicle Standards Agency’s (DVSA) national waiting time target for driving tests is six weeks.
But the UK Government Department for Transport website states waiting times are currently at 14 weeks.
Aberdeen South MP Callum McCaig, SNP, has written to Under Secretary of State Tariq Ahmad about delays after constituents raised concerns.
Mr McCaig said: “One of the most frustrating aspects of this is waiting times are longer since I first raised this issue before Christmas.
“These days a lot of jobs require people to have a valid driving licence.
“We cannot allow Aberdonians to lose out because of the UK Government’s poor foresight and recruitment organisation.”
DVSA head of operations Phil Lloyd admitted there were delays.
He said: “Demand for driving tests is increasing and we acknowledge waiting times are currently higher than we would like in some areas.
“We are working to address this as quickly as possible and have been running driving examiner recruitment campaigns throughout 2015, which have resulted in 139 new examiners starting work at test centres across Great Britain.
“We have also made offers to another 115 people, and they are currently on the new entrant training course or waiting to attend it.”
