“It must only be used for the disabled person’s personal needs. It cannot be used by the nominated driver for their own personal use”
Going to work also meets the disabled personal needs, as it buys food to keep them alive and a roof over their head ot going out to buy toilet role, would also meet personal needs…..
However, it can’t be used by the nominated driver for their sole pleasure, unless there is a benefit to the disabled person, like being told to get out of their space for an hour. This also applies to Motability rules.
