Armored cars are designed to resist attempts at robbery and hijacking, being able to withstand bullets from most handguns and rifles, as well as extreme degrees of heat, explosives, and collisions.The earliest form of armored transportation for valuables that actually went into production were the "ironclad" treasure wagons designed by the Cheyenne and Black Hills Stage Company during the American Old West.Many jewelers use armored cars to transport jewelry and materials to their stores, as the valuable nature of such items make them vulnerable to potential robbery attempts.With the advent of GPS technology, armored cars are often equipped with tracking devices that can be monitored by the company, letting them see if the vehicle leaves the planned route.Training may also include guidance on remaining calm in emergency situations, such as confronting armed criminals; assisting injured colleagues; notifying local law enforcement; following traffic rules; and choosing the safest routes for transportation.[6] Five member states of the European Union, namely Denmark, Greece, Ireland, Sweden, and the Netherlands, as well as the United Kingdom, prohibit weapons during cash-in-transit (CIT) operations.
