A truck driver is someone who is the driver of a large commercial vehicle called a truck. Typically, a truck driver transports goods over land from manufacturing plants to warehouses, distribution centers, and retail locations. Truck driving is an important sector of the industrialized world, and they are integral to places such as the United States.

In North America, independent truckers are owner-operated truck drivers that own their trucks and lease them out to either one or more companies to move their goods, whereas company truckers are drivers that just drive their company-owned trucks.

To avoid bad accidents due to driver fatigue, periods of driving are limited to 11 hours with a 10-hour break necessary immediately after that. Many truckers ignore this rule to earn more money, and it can lead to disastrous consequences.

There are many categories that both owner and company-owned truckers can come under such as auto haulers, dry van drivers, flat bed drivers, etc. All truck drivers are required to hold a special license called a Commercial Driver's License, which allows truck drivers to drive legally. One can obtain this license from the state truckers program, and the guidelines are pinpointed in federal law. Federal law also points out if any necessary special licenses are needed for special cases.

Special cases involve the transportation of hazardous materials, double and triple trailers, and tankers. The five-axle tractor-semi trailer is the most common form of 'truck,' and anything that goes above and beyond that is endorsed specifically from the company involved to make sure everything is legal and legitimate.
