Ask him to let you see his court and sentence documents.
If he doesn't have them, ask him to write a letter to the court requesting them.
His responses should tell you everything you need to know.
First Conviction:
Must complete DUI school before hardship reinstatement. Customers who wait out revocation period before reinstatement need only show proof of enrollment or completion to become re-licensed. If customer enrolls and is reinstated after revocation period expires,
failure to complete the DUI school within 90 days after reinstatement will result in license cancellation; the driver cannot then be re-licensed until DUI school is completed.
