In Carlton v. State, 176 S.W.3d 231, 236 (Tex. Crim. App. 2005) the court addressed whether the allegation of a prior conviction under the evading arrest statute was an element of the offense. The court explained that when determining "whether any given fact constitutes an element of the offense," the court must look to the plain language of the statute involved and apply that plain language if it is not ambiguous.
