As an independent courier driver, you own a vehicle, and your duties are to deliver important documents or transport packages to clients. As a courier, your responsibilities include ensuring the packages and documents arrive safely with clients, logging all deliveries, and getting signatures from clients. The types of goods or documents you delivered depend on the type of vehicle you own. For example, if you have a pickup truck or sprinter van, you can deliver packages for retailers or contract with delivery companies when they need extra delivery drivers, especially during a busy season or holiday.
