The South Carolina Implied Consent Law requires you to take a blood, breath or urine test if you’re arrested by an officer for suspicion of DUI/DWI. This law means that if you operate a vehicle in the state of South Carolina, you automatically consent to being tested for alcohol or drugs if you are lawfully arrested by an officer who has reason to suspect that you are driving under the influence. If you refuse to take the test, the penalty is an automatic six-month driver’s license suspension for the first offense. The six-month suspension applies only if you have not had any previous violations of South Carolina DUI laws within the past 10 years. Otherwise, the suspension period is up to one year.
