How often must a CDL holder renew their license in Pennsylvania?

A CDL holder in Pennsylvania is required to renew their license every 5 years. This periodic renewal helps ensure that drivers continue to meet the necessary safety and regulatory standards associated with operating commercial vehicles. Regular renewals provide an opportunity for the state to confirm that there have been no significant changes in the driver's status, such as medical issues or violations that could affect their ability to drive safely. This interval also allows for the updated dissemination of new driving laws or regulations that CDL holders must adhere to, helping maintain road safety for all users.
