Choosing The Right South Dakota DUI Attorney

Going through the process of a DUI defense in South Dakota is crucial and it is important to have someone represent the case who understands DUI law. Ask the following questions before choosing a DUI attorney in Sioux Falls:

  • How many years have you practiced DUI law in South Dakota?

  • What counties are you experienced in?  Minnehaha, Lincoln, Brookings, Clay, Davison, Lake, Moody, Union, Turner, McCook, Yankton? 

  • How many South Dakota DUI cases have you defended? How many in the last year? What is your success rate?

  • What percentage of DUI cases go to trial?

  • Do you work with breathalyzer and/or blood test toxicologists? Please explain your understanding of alcohol toxicology in relation to a DUI Arrest.

  • Do you have experience with drug DUI cases?

  • How frequently do you file a motion to suppress the evidence on DUI cases?

  • Do you have experience with DUI cases based upon being in “actual physical control” and not driving the motor vehicle?

Drug Related DUI Offenses

​We have great deal of experience defending DWI/DUI cases. Some of our clients have been accused of being under the influence of a drug(s) or a combination of drugs and alcohol while driving.  In a drug DUI case, it is important to hire an attorney that is familiar with the specialized tests (Drug Recognition Examination- DRE) that law enforcement may use while investigating drug-based DUI cases. Drug-related DUI case investigations typically involve many more field sobriety tests than an alcohol-based DUI. In addition to the differing field sobriety tests, a portion of drug DUI investigations usually take place at a police station or law enforcement center before the defendant is taken to the jail or booked into custody. If these tests were not completed, it could greatly reduce the strength of the State’s case.

Restricted Permit or Work Permit for DUI or DWI Convictions

​Ryan Duffy Law can also advise you on how to obtain a work permit (restricted driving permit) if your license is revoked because of a DUI conviction, applying for SR-22 vehicle insurance, and getting your driver’s license back at the end of a revocation period.  We can assist you in dealing with bond conditions that are commonly imposed for an alcohol related charge.  The Court often orders defendants to comply with the 24/7 sobriety program as a condition of release if they have been charged with a DUI. We can help educate you on the different options available to you.  The most common 24/7 sobriety program options include: twice daily PBT(s) (preliminary breath tests), utilization of the SCRAM alcohol ankle monitor, or use of a portable PBT unit (remote breath).
