Is my Thai driver's license from thirty years ago still valid?

The original poster inquired about the validity of their Thai driver's license issued thirty years ago, which did not have an expiry date. Responses varied, with some confirming that the lifetime licenses are still valid, while another commenter advised to refer directly to Thai authorities for accurate information. However, recent changes in regulations were mentioned, indicating that current licenses need to be renewed every two years, with options for longer periods thereafter.
