What is the minimum age requirement to apply for a Commercial Driver's License (CDL) in Louisiana?

In Louisiana, the minimum age requirement to apply for a Commercial Driver's License (CDL) is indeed 18 years old. This age requirement allows individuals to operate commercial vehicles within the state borders. However, while you can obtain a CDL at 18, to drive across state lines or transport hazardous materials, you must be at least 21 years old. This regulation helps ensure that drivers have sufficient experience and maturity to handle the complexities of commercial driving, which often involves larger vehicles and more demanding road conditions. Therefore, the correct answer reflects the state policy aimed at ensuring safety on the roads.
