What is the minimum age for drivers to operate combination vehicles under Texas law?

Under Texas law, the minimum age for drivers to operate combination vehicles, such as tractor-trailers, is 18 years. This requirement is in place due to the complexity and responsibility associated with handling large and potentially dangerous vehicles that can carry heavy loads. Drivers must possess a valid Commercial Driver's License (CDL) to operate these vehicles, which is only issued to individuals who are at least 18 years old for intrastate driving or 21 years old for interstate driving. This age requirement helps ensure that drivers have sufficient maturity and experience to safely navigate the roads while operating larger vehicles that require a higher level of skill and attention.
