Has an officer stopped you for suspicion of driving under the influence? The officer may have asked you to perform a number of 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.
