Final answer:
To get a commercial driver's license in the U.S., you must be at least 18 years old for intrastate transport and 21 for interstate transport, with individual states possibly having additional specific requirements.
Step-by-step explanation:
In order to obtain a commercial driver's license (CDL) in the United States, individuals must meet the minimum age requirement, which is typically 18 years old for intrastate transport (transporting goods within a state) and 21 years old for interstate transport (transporting goods between states). These age requirements allow the government to ensure that commercial drivers have reached a level of maturity and responsibility necessary for the safe operation of commercial vehicles. It is important to note that while the federal government sets these general standards, each state may have its own specific requirements and processes for obtaining a CDL.
