Our firm is prepared to assist you with fighting a criminal charge or protecting your rights during an investigation in which you are involved. A common type of charge that a North Carolina resident may face is a DWI (driving while impaired). According to North Carolina law, a driver who operates a motor vehicle with a blood alcohol content level of 0.08% or higher is guilty of DWI. To measure an individual’s BAC, field sobriety and breathalyzer tests are often used on the scene. There are highly specific procedures that officers are supposed to follow when administering these exams, and an error in the process may lead to the result being suppressed and the charge being dropped. It is also possible that the officer may not have had a sufficient reason to stop the driver, which would prevent the prosecution from using anything that happened during the stop.
