In most drunk driving cases in Wake County, the District Attorney attempts to prove impaired driving by demonstrating either that the person was “appreciably impaired” at the time he or she was driving, or the person blew a .08 or higher on the Intox EC/IR machine that is used at the Public Safety Center (Jail) or other departments in Wake County.
Your drunk driving case may therefore may be proved either by the officer who arrested you, or the officer in conjunction with the chemical analyst. About half of all of the law enforcement officers in Wake County are also chemical analysts, which means that the same person who arrested you will also testify about the breathalyzer results.
This makes it less likely that your case would be dismissed because of the absence of the chemical analyst, since the chemical analyst is also the arresting officer.
