How often must a Commercial Driver's License be renewed in Louisiana?

In Louisiana, a Commercial Driver's License (CDL) must be renewed every 4 years. This renewal period helps ensure that drivers maintain their skills, knowledge, and compliance with updated regulations or requirements as they evolve over time. Regular renewal is critical for safety on the roads, as it prompts drivers to stay informed about current laws, safe driving practices, and any changes in their health that may affect their ability to operate a commercial vehicle effectively. This structure also helps the state keep its records up to date and ensures that commercial drivers are periodically re-evaluated as technology and road safety protocols develop.
