Tex. Transp. Code § 548.255

If an inspection discloses the necessity for adjustment, correction, or repair, an inspection station or inspector may not issue a passing vehicle inspection report until the adjustment, correction, or repair is made. The owner of the vehicle may have the adjustment, correction, or repair made by a qualified person of the owner's choice, subject to reinspection. The vehicle shall be reinspected once free of charge within 15 days after the date of the original inspection, not including the date the original inspection is made, at the same inspection station after the adjustment, correction, or repair is made.
