Drivers are being urged to book an MOT early this year to avoid a backlog as the pressure of the pandemic mounts on mechanics.
Experts have predicted a surge in bookings after the Driver and Vehicle Standards Agency (DVSA) granted a six-month extension on MOTs last year due to Covid.
This extension will change what was once an even spread of MOTs across the year, to a high concentration in the latter months of 2021.
Car-owners are now being urged to book their vehicles in as soon as possible to help ease the strain during autumn and winter.
The surge in demand is expected to come not from those who took advantage of the extension but for those who have a MOT due in October, November, and December.
Motorists will need to book their vehicles in order to remain road legal - and to avoid a fine for driving without a valid MOT certificate.

A spokesperson for LeaseCar.co.uk said: “Over the last 18 months garages have felt the pressure from the sheer volume of work that they are receiving.
“We’re encouraging those who haven’t already to book their MOT’s in good time, as to avoid the last-minute rush and relieve the pressure on mechanics.
“Not only this but as we move into the autumn and winter period it’s important that our vehicles are safe for the roads especially as the conditions begin to change.
Concerns not only surround the road safety and legality of British motorists but also the mental and physical strain on the country's mechanics.

MOTs must be renewed every 12 months unless your vehicle is less than three years old, in which case an MOT must be carried out on its third anniversary.
The fine for driving without a valid MOT certificate can be anywhere up to £2,500 and in some cases three points on your licence.
According to GOV.uk the maximum charge for an initial car MOT is £54.85 and £29.65 for a motorcycle.
