A trolley bay is a designated, secure, and easily visible area in a car park designed to hold shopping trolleys, preventing them from becoming hazards or causing clutter. These bays serve as a convenient central point for customers to return their trolleys after use, ensuring the trolleys are organized, reducing potential damage to vehicles, and streamlining the process for staff collecting them for return to the store. They are typically made of metal, come in modular or welded designs, and are found in shopping centres, supermarkets, and other commercial area.
