Section 15.21 - SignatureThe applicant's usual signature is required on all applications for a driver license or identification certificate.
(1) The usual signature is preferred. If a man's name is John Henry Jones and his usual signature is J.H. Jones, he should so sign it. This section also applies to women. The usual signature is asked for simply because it will not disturb the applicant so much as it would to require the full name.(2) The signature on the application must be in ink. The license or certificate must include a facsimile of the license holder's signature or a space on which the holder shall write the holder's usual signature in ink immediately on receipt of the license or certificate.(3) The primary purpose of the signature is to identify the applicant and verify the information given on the application.(4) If an applicant cannot write his name, he may make his "mark." This is usually a cross in the place of his signature followed by the applicant's printed name. The Driver License field employee shall sign under the applicant's "mark" showing who printed the applicant's name.37 Tex. Admin. Code § 15.21
