CDL Drivers provide critical transportation of goods and people for businesses and public agencies. They work in a variety of industries, including transportation, manufacturing, automotive, public works, construction and service. Across all industries, commercial drivers must maintain a high standard of care on the road and follow the regulations and rules that govern their license. Commercially licensed drivers may work as owner-operators of large trucks, contracting with businesses to provide services. They may also work as employees of trucking companies or specific organizations that need regular delivery or transportation services.
