What age must a driver be to apply for a Commercial Driver's License (CDL) in Texas?

In Texas, a driver must be at least 21 years old to apply for a Commercial Driver's License (CDL). This requirement is in line with federal regulations that govern the operation of commercial vehicles across state lines, ensuring that drivers have reached a level of maturity and responsibility necessary for handling larger and more complex vehicles. While there are provisions for drivers as young as 18 to obtain a CDL for intrastate driving—meaning within Texas only—they cannot engage in interstate commerce until they are 21. Thus, the age requirement is designed to enhance safety on the roads by ensuring that commercial drivers are adequately mature and responsible enough to operate large vehicles that require special skills and handling.
