(4) show the vehicle identification number; and

(c) A permit holder must keep the cab card in the cab of each permitted tow truck.
(d) The department may order a permit holder to surrender a cab card if the permit is suspended or revoked under this chapter.
(e) If the department determines that the cab card system described by Subsections (a) through (c) is not an efficient means of enforcing this subchapter, the executive director by rule may adopt an alternative method that is accessible by law enforcement personnel in the field and provides for the enforcement of the permit requirements of this subchapter.
(f) A cab card or a permit issued under the alternative method described in Subsection (e) must be valid for the same duration as a certificate issued under Section 2308.106.
