Your car, van or motorcycle’s MOT expiry date will be extended by 6 months if it’s due on or after 30 March 2020 - but you must keep your vehicle safe to drive.

I am guessing if you have a vehicle with an expired MOT already and want it on the road to use (for shopping obviously) then you still need to get it MOTed.
