In every state, it is illegal to operate a vehicle while under the influence of drugs or alcohol. In South Dakota, this crime is referred to as driving under the influence (DUI), while in some other states it is referred to as driving while intoxicated (DWI). This article provides an overview of South Dakota's main DUI laws.
Code Section |
South Dakota Code section 32-23-1: Driving Under the Influence |
What's Prohibited? |
No person may drive or be in actual physical control of a vehicle while:
|
| Lawful Use of Drugs is No Defense | The fact that a person charged with driving under the influence has been prescribed a drug isn't a valid defense under this section. |
Penalties |
The penalty for a DUI offense varies depending on whether the offender has been convicted of driving under the influence in the past (and if so, the number of times), and on how drunk the offender was at the time of the arrest. For a first DUI offense with a blood alcohol concentration of 0.08% to 0.16%: Class 1 misdemeanor punishable by up to one year in jail and/or a fine of up to $2,000. Additionally, the defendant's driving privileges will be revoked for at least 30 days. The court may also revoke the defendant's driving privileges for a period of up to one year, or restrict the privilege in a manner that the court sees fit for up to one year. However, the court may allow the defender to drive to and from work, sobriety testing, school, or counseling programs. If arrested with a 0.17% or greater blood alcohol concentration: Any person convicted of driving under the influence with a blood alcohol concentration of 0.17% or greater will also be required to undergo a court-ordered evaluation by a chemical dependency counselor. |
Because the legal drinking age in South Dakota is 21, drivers who are under 21 may be convicted of driving under the influence if they have a blood alcohol concentration 0.02% or greater. It is a Class 2 misdemeanor for any person under the age of 21 to drive, operate, or to be in actual physical control of any vehicle:
Underage driving under the influence in South Dakota is punishable by up to 30 days in jail, and/or a fine of $500. Additionally, the court will suspend the offender's driver's license for 30 days for a first offense, 180 days for a second offense, or one year for a third or subsequent offense. However, the offender may be permitted to drive to and from work, school, or counseling programs.
