As the driver of a delivery or independent contractor cargo van, your duties are to deliver goods or services on behalf of your clients. Many van drivers work on temporary contracts or during seasonal upturns in business. Your responsibilities generally are to pick up shipments from your clients or from a centralized shipping depot, transport them to other clients along a specified route, and ensure that you make all deliveries promptly. Some delivery drivers transport perishable goods, such as flowers, food, or medical materials, so you need to have the proper storage equipment in your cargo van.
