Delivery truck drivers and driver/sales workers typically do the following:

• Load and unload their cargo
• Communicate with costumers to determine pickup and delivery needs
• Report any incidents they encounter on the road to a dispatcher
• Follow all applicable traffic laws
• Report serious mechanical problems to the appropriate personnel
• Keep their truck and associated equipment clean and in good working order
• Accept payments for the shipment
• Handle paperwork, such as receipts or delivery confirmation notices

Most drivers generally receive instructions to go to a delivery location at a particular time, and it is up to them to determine the best route. Other drivers have a regular daily or weekly delivery schedule. All drivers must have a thorough understanding of an area's street grid and know which roads allow trucks and which do not.

Light truck drivers, often called pickup and delivery or P&D drivers, are the most common type of delivery driver. They drive small trucks or vans from distribution centers to delivery locations. Drivers make deliveries based on a set schedule. Some drivers stop at the distribution center once only, in the morning, and make many stops throughout the day. Others make multiple trips between the distribution center and delivery locations. Some drivers make deliveries from a retail location to customers.

Driver/sales workers are delivery drivers who have additional sales responsibilities. They recommend new products to businesses and solicit new customers. These drivers may have a regular delivery route and be responsible for adding new clients located along their route. For example, they may make regular deliveries to a hardware store and encourage the store's manager to offer a new type of product. Driver/sales workers also deliver goods, such as take-out food to consumers, and accept payment for those goods.
