What do i do with regards to giving the drivers details as it says it must be filled in, obviously the DVLA should have the log book by now and it should be changed over within a few days? The speeding ticket was issued on the 8th August, we got sold the car on 7th.
I need the drivers license number how on earth am i supposed to know that

as well as drivers date of birth, name and address.
I crapped myself when i opened it
