Yeah, I know it is an old thread but I just read it:

Sec. 546.002. WHEN CONDUCT PERMISSIBLE. (a) In this section, "police escort" means facilitating the movement of a funeral, oversized or hazardous load, or other traffic disruption for public safety purposes by a peace officer described by Articles 2.12(1)-(4), (8), (12), and (22), Code of Criminal Procedure.
(b) Section 546.001 applies only when the operator is:
