South Dakota DUI Laws
South Dakota DUI / DWI laws make it a crime for you to drive while under the influence of alcohol or drugs. It is a per se violation to have a blood or breath alcohol level (BAC) of .08 percent or higher (less for commercial and underage drivers). Even if your BAC is under the legal limit, you can be guilty of impaired driving if the prosecution can prove its case with other evidence such as erratic driving patterns and field sobriety tests. A DUI lawyer is best qualified to challenge the credibility of the evidence to make certain you have the best possible outcome for your case.
South Dakota "looks back" 10 years at the number of DUI convictions to determine whether the defendant is charged with a first, second, third or subsequent offense. Conviction penalties will vary depending on the facts and circumstances of your case but might include fines, incarceration, alcohol evaluation (for high-BAC drivers), community service, home confinement with electronic monitoring, intensive supervision, probation, victim impact panel and special assessments/surcharges (e.g., you may be required to pay the cost of confinement in county jail). A lawyer specializing in South Dakota DUI can tell you what to expect in your case.
Like other states, South Dakota has an implied consent law that makes it a crime to refuse a request for chemical testing (with probable cause) for drugs and alcohol. However, unlike other states, South Dakota is one of the only jurisdictions that does not utilize ignition interlock devices (as a penalty, condition for driving or other application). The laws are constantly evolving, so it is best to consult a South Dakota DUI lawyer for the most current information.
