Regarding the three-month driving test suspension, be aware that the rearranged dates in June cannot be changed right now.
One of my pupils texted me tonight and said the time on the new date she’s been given isn’t convenient, but she couldn’t change it. I asked her for the booking reference so I could have a look and even on the first page the message above makes it clear you cannot do anything right now. If you do try to proceed further, you get this message.
It’s fairly clear. The entire DVSA is effectively closed as far as test bookings etc. go.
