What is required to renew a Class B Exempt License in Texas?

To renew a Class B Exempt License in Texas, it is essential to undergo a vision test to ensure the driver's eyesight meets the required standards for safe driving. In some cases, a written test may also be required, particularly if it is determined that the renewal conditions necessitate it, such as having certain violations or being due for additional evaluation. This helps maintain road safety by ensuring drivers still meet the necessary requirements to operate a vehicle safely.
