Should just a simple test on the highway code, driver’s hours, etc, followed by a drive around the block, and maybe a reverse onto a bay.
Don’t forget to fill in an OPS13 (vehicle checklist) form, and have at least 15 minutes (DHL policy) on other work after you put your card in before you turn a wheel.
And also, you should get a “passport” which covers all DHL sites in the UK.
I wish you the very best of luck, and hopefully, you should cream it with no problems at all.
Garbo.
