Do Implied Consent Procedures Apply to the Withdrawal of Blood Pursuant to a Search Warrant?

In most DWI cases, the State obtains evidence of a defendant’s alcohol concentration from a breath-testing machine.  In order for the results of such a breath test to be admissible at trial, the State must follow the procedures set forth in the implied consent statutes, G.S. 20-16.2 and G.S. 20-139.1. Those statutes require, among other things, that a suspect be advised of his right to refuse testing and the consequences of such a refusal and that he be afforded an opportunity to contact a witness to observe the testing. Less frequently, a law enforcement officer will request that a person charged with an implied consent offense such as impaired driving submit to a blood test. Like the breath test results, the analysis of the defendant’s blood sample obtained pursuant to such a request is admissible at trial only if the State follows the procedures set forth in the implied consent statutes.  If the request for a blood test follows an earlier request for a breath test, then the officer must re-advise the suspect of his implied consent rights before asking for consent.  None of these rules apply, however, when blood is withdrawn pursuant to a search warrant.
