Driving tests have been suspended for at least three months to help tackle the spread of coronavirus.
MOT tests for lorries, buses and trailers have also been suspended from Saturday.
However, critical workers will still be allowed to sit driving tests.
The Driver and Vehicles Standards Agency (DVSA) announced the measures and say they are being put in place to help prevent the spread of the virus as tests can lead to extended contact between candidates and examiners in vehicles.
UK transport secretary Grant Shapps said: “We are having to take big decisions to protect the public in our national battle against COVID-19. Regrettably, we have had to suspend driver testing for up to three months to help tackle the spread of the virus.
“It is vital that those who need a test can get one so DVSA is offering tests to those who have a critical need, such as the NHS and drivers delivering goods across the UK.
“Those who have tests cancelled will have priority when testing resumes.”
The suspension is in force in Scotland, England and Wales and covers car driving, motorcycle, lorry, coach and bus driving tests as well as approved driving instructor (ADI) tests and checks.
The DVSA say they will contact everyone with a test booked during this time to let them know it has been cancelled and one will be rebooked for them.
MOT checks for lorries, buses and trailers are also suspended for three months from Saturday.
All HGV and PSV vehicles with an MOT will be issued with a three-month temporary exemption certificate until further notice.
The UK department of transport say they will continue to keep MOT testing under review for cars, motorcycles and light vans.
