Lorry driver (Children of Earth: Day Two)

From Tardis Wiki, the free Doctor Who reference

One lorry driver for Harwood's Haulage once unknowingly transported Gwen Cooper and Rhys Williams, in the back of his lorry carrying raw potatos, from Cardiff to London. The driver finished his sandwich at Tony's Sandwich Bar across the street before leaving.

As transport manager, Rhys knew that the back of the lorry had an electronic code that even the driver didn't know, so he couldn't open it until he reached his destination. Once in London, the lorry driver had to brake for a line of children that suddenly stopped moving on the road. (TV: Children of Earth: Day Two)
