The DUI statutes nowhere provide for a suppression remedy for procedural violations. Instead, Code § 18.2-268.11 states that a violation of the procedural steps of Code §§ 18.2-268.2 through 18.2-268.9 “shall go to the weight of the evidence and shall be considered with all the evidence in the case.” See Shumate v. Commonwealth, 207 Va. 877, 883, 153 S.E.2d 243, 247 (1967) (<HOLDING>); Snider v. Commonwealth, 26 Va.App. 729, 734,
