A driver received this
The notice you have shown us is not addressed to any driver, it is addressed to Alphabet GB Ltd.
Can the driver appeal this..
No, as it is not addressed to them. At any rate, the driver should not be dealing with this. As it is a hire/lease car, the hirer should deal with any appeals, but at present, there is nothing for them to appeal. The hirer should speak to Alphabet, and ask if they have followed the instructions on the back of the notice, to transfer liability to the hirer. Once they have done that, the hirer should receive a notice in their own name.
Did the hirer receive anything else from Alphabet, other than that PDF?
