Has an officer stopped you for suspicion of driving under the influence? The officer may have asked you to perform several field sobriety tests. These tests may have led the officer to ask you to submit a breathalyzer test. The South Carolina Implied Consent Law requires drivers to take a breath or other DUI/DWI test if an officer has reason to suspect driving under the influence. In other words, when you obtain a state driver’s license, you imply that you will agree to provide a DUI test upon an officer’s direction.
