Those who have been offered an extension up until July will still be able to delay exams until the new date.
However those who are due to have a test in August will not be offered an extension and must get a test secured before their original due date.
This means many motorists who are due to have an exam in August must secure a valid MOT pass certificate to remain on the roads.
Those caught breaking the rules could face strict £1,000 fines and extra charges if their car is impounded.
This information can be accessed by anyone with your number plate and shows up on systems used by police cars Automatic Number Plate Recognition (ANPR) cameras.
This could lead to drivers being prosecuted for their actions and then issued heavy fines and penalties.
Driving without a valid MOT certificate could also put drivers at risk of invalidating their car insurance policy.
This could lead to drivers being issued heavy chargers to repair their vehicle and may leave owners blacklisted from securing affordable cover.
Experts have warned drivers could be caught out by the latest rule change through simply not being aware the extension scheme had ended.
Roads Minister Baroness Vere saId: “As people return to our roads, it is vital that motorists are able to keep their vehicles safe.
“That’s why as restrictions are eased, from 1 August MOT testing will again become mandatory.
“Garages across the country are open and I urge drivers who are due for their MOT to book a test as soon they can.”
The DfT has issued specific advice to any motorists who are vulnerable or self-isolating and still require a test
Affected drivers should contact their local garage for assistance as many are offering pick-up and drop-off services.
This will ensure drivers can get their car checked and avoid being issued fines without having to visit a garage.
