In Ex parte Ross, 522 S.W.2d 214 (Tex. Crim. App. 1975), the defendant challenged his DWI conviction by arguing that Tex. Penal Code section 6.02 required proof of a culpable mental state. Id. at 218. The Court of Criminal Appeals held that despite section 6.02, the State was not required to prove a culpable mental state in obtaining a DWI conviction. Id. at 218-19. Specifically, the court reasoned that the legislature did not intend to require proof of a culpable mental state for DWI when section 6.02 was enacted. Id. at 219.
