What is the required minimum age to obtain a Texas commercial driver’s license (CDL) for bus drivers?

To obtain a Texas commercial driver’s license (CDL) for driving a bus, the minimum age requirement is 18 years old. This age requirement aligns with federal regulations, which allow individuals as young as 18 to drive commercial vehicles within state lines. However, it's important to note that while 18 years old is the minimum age for intrastate driving, individuals must be at least 21 years old to operate a commercial vehicle across state lines or carry hazardous materials. Thus, the answer of 18 years old is correct for obtaining a Texas CDL specifically for driving a bus within the state.
