Customers have been asked to report drivers who misuse parent and child parking bays. The RAC says: “Parent and child parking bays are found in private car parks across the country, particularly in supermarkets. The Blue Badge scheme mainly applies to parking on public roads and local authority car parks. You won't usually receive a council Penalty Charge Notice because supermarket car parks are private land. These concessions generally do not automatically extend to private supermarket or retail park car parks.
