Thanks Trev.
I just called DVLA and I’m very surprised!
Firstly got through to a human within 60 seconds…
And she told me that my license is ready to go and is being posted out tomorrow. I only sent it in last Thursday. Quick turnaround
She also said that I was legal to drive as soon as passed test, still sounds like a grey area though as you say if you have to explain it at the roadside.
Moot point for me now though cheers
