The transport secretary has pledged to reduce the number of learner drivers in England waiting more than five months to sit practical tests.
Heidi Alexander said the government would aim to clear the backlog by next summer, providing at least 10,000 extra driving tests a month to help tackle the issue.
Current driving test wait times are "totally unacceptable", she told parliament's transport committee on Wednesday.
There is a minimum six-month wait to book a driving test in several areas of the UK, according to data from the AA.
The transport secretary said the new measures would help reduce average waiting times to no more than seven weeks by summer 2026.
It means the government is set to miss its original target for waiting times by up eight months.
The Driver and Vehicle Standards Agency (DVSA) had planned on cutting waiting times to seven weeks by the end of this year. It has blamed an "increase in demand and a change in customers' booking behaviour" for the backlog.
In order to tackle the delays, Alexander revealed plans to double training capacity so more driving examiners would be available.
She said she was also asking those in other DVSA roles who are qualified, but not longer examine, to temporarily "return to the frontline".
She said it would also reintroduce overtime pay incentives for everyone delivering driving tests.
A record 1.95 million tests were booked last year, but the government would now consult on changes to the test booking system, Alexander added.
