South Carolina drivers arrested on DUI charges will be pleased to hear that a DUI arrest, even if it comes with a breathalyzer test that seems to prove a high alcohol content, will not necessarily result in a DUI conviction. Indeed, it is important to remember that breathalyzer tests results are not always accurate, and state courts are fully aware of this fact.
According to South Carolina DUI law, for example, a failed breathalyzer test is not sufficient evidence to prove someone is guilty of drunk driving. State prosecutors must also show evidence of impairment. This is why police submit drivers to field sobriety tests and take detailed notes with regard to the outward behavior and appearance of drivers.
