What To Know About DUI Charges In South Dakota
Driving under the influence is one of the most common South Dakota criminal charges. The state can charge you with DUI if law enforcement believes that you operated a vehicle while impaired by alcohol, drugs or a combination of both. This applies whether you are driving a car, motorcycle or even a boat. Some examples include driving with a blood alcohol content over the legal limit or refusing to take a breath test. A DUI attorney can explain your options and help you understand what you are facing.
Facing The Penalties For A South Dakota DUI
A DUI conviction can bring harsh penalties. Even a first offense can have long-lasting effects. Possible penalties include:
- Fines and court costs
- Jail time
- Loss of driving privileges
- Mandatory alcohol treatment or classes
- Installation of an ignition interlock device
- Increased insurance rates
The consequences of such a criminal offense become even more severe with repeat offenses or if someone was injured. Our DUI attorneys work hard to protect your rights and limit the impact of criminal charges on your future and your family.
Don’t Forget The Long-Term Effects Of A DUI Conviction

You could lose job opportunities and educational options. A DUI can also cause your reputation to take a permanent hit. With so much at stake, you need a dedicated DUI attorney on your side.

Frequently Asked Questions About DUI Charges In Sioux Falls
Our Sioux Falls DUI defense attorneys answer common questions from clients facing driving under the influence charges in South Dakota.
Can I refuse a breathalyzer test in South Dakota?
You can refuse a breathalyzer test in South Dakota, but doing so carries significant consequences under the state’s implied consent law. When you obtain a driver’s license in South Dakota, you automatically consent to chemical testing if law enforcement has reasonable grounds to believe you are driving under the influence.
Refusing the test results in immediate administrative penalties separate from any criminal DUI charges. Your driver’s license will be suspended for one year for a first refusal and two years for subsequent refusals. The prosecution can also use your refusal as evidence of consciousness of guilt in court, suggesting you knew you were intoxicated and tried to hide evidence.
How quickly can you start working on my DUI case?
We can begin working on your DUI case immediately after you contact us. Time is critical in DUI cases because South Dakota imposes strict deadlines for challenging license suspensions and requesting administrative hearings. You typically have only 30 days from your arrest to request a hearing to contest the administrative license suspension.
Missing this deadline means your license suspension becomes automatic. We prioritize DUI cases and move quickly to protect your driving privileges while building your criminal defense. During your initial consultation, we gather information about your arrest, review any documentation you have and explain the timeline ahead.
Can a DUI be expunged from my record in South Dakota?
Expungement allows a person convicted of a DUI to clear their criminal record from public view. Expunging a criminal record can restore a person’s rights. South Dakota does offer expungement for DUI convictions under certain conditions. You may be eligible for an expungement if you meet the following qualifications:
- There was a DUI charge, but no conviction and 180 days have passed since the arrest.
- If you were convicted of a misdemeanor DUI charge and at least one year has passed since the conviction or five years since the end of a sentence.
- If you were convicted of a felony DUI charge and at least 10 years have passed since completing a sentence.
Our attorneys can help you explore your expungement options.
