Underage First Offense DUI


In South Dakota, underage drivers face specific penalties for a first-offense DUI, which are notably distinct from those for adults. If an underage driver is found with a blood alcohol concentration (BAC) of 0.02% or higher, they violate the state’s zero tolerance law and can be convicted of a Class 2 misdemeanor. The key consequences include a license suspension for 30 days on a first offense. If the BAC is 0.08% or higher, the underage driver faces the same penalties as an adult, which generally includes jail time, fines, and potential installation of an ignition interlock device​ (dui.drivinglaws.org)​​ (Legal Beagle)​.

Moreover, the overall approach to underage DUIs emphasizes rehabilitation, aiming to correct behavior through measures like mandatory participation in substance abuse programs and possible restricted licenses for essential travel (to work, school, etc.), following program completion and reinstatement processes involving SR22 insurance​ (Legal Beagle)​.

CDL First Offense DUI Penalties

In South Dakota, the penalties for a first offense DUI while holding a Commercial Driver’s License (CDL) are severe due to the lower allowed blood alcohol concentration (BAC) limits for commercial drivers. Here are the key points regarding a first offense CDL DUI in South Dakota:

  1. BAC Limit for CDL Holders: CDL drivers are held to a stricter standard than non-commercial drivers. If you’re operating a commercial vehicle, a BAC of 0.04% or more is considered over the legal limit, compared to the general limit of 0.08% for non-commercial drivers.
  2. Penalties and Disqualifications: For a first offense DUI with a BAC of 0.04% or more, a CDL driver will face a one-year disqualification of their commercial driving privileges. If the offense involves transporting hazardous materials, this disqualification extends to three years.
  3. Additional Consequences: Beyond the immediate disqualification, drivers can also face additional criminal penalties similar to those for non-commercial DUI offenses, such as potential jail time, fines, and the requirement of an ignition interlock device, depending on the circumstances of the case.

The state takes these violations seriously, especially given the potential safety risks associated with operating large commercial vehicles. CDL holders are therefore strongly advised to avoid consuming alcohol entirely before or while driving commercial vehicles.

For more specific details on navigating these laws or legal assistance, it’s advisable to consult resources or legal experts familiar with South Dakota’s transportation and DUI laws​ (dui.drivinglaws.org)​​ (SD Truck Info)​​ (DUI Process)​.

Ignition Interlock Requirements First Offense DUI

In South Dakota, a first offense DUI does not automatically require the installation of an ignition interlock device (IID) for all offenders. The requirement to install an IID typically depends on specific factors such as the driver’s Blood Alcohol Content (BAC) level at the time of the arrest or other court orders. Generally, higher BAC levels or additional circumstances might influence such a mandate as part of the conditions for reinstating driving privileges or obtaining a restricted license.

However, South Dakota laws do allow courts the discretion to order the installation of an IID as part of the penalties for a DUI offense, which could include situations involving higher BAC levels or other aggravating factors. It is advisable for individuals facing a DUI charge in South Dakota to consult legal counsel to understand the specific requirements and conditions that may apply to their case​ (Intoxalock)​​ (DUI Arrest Help)​.

Implied Consent Law

South Dakota’s implied consent law states that by driving on the roads, drivers are deemed to have given their consent to chemical testing to determine their alcohol concentration or the presence of drugs. Under this law, if you’re arrested for a DUI and you refuse to submit to a blood, breath, or urine test, your driver’s license will be revoked for one year for a first offense refusal. This refusal can also be used as evidence against you in court. The law is meant to discourage drivers from refusing tests, as such actions are viewed negatively and carry significant administrative penalties​ (dui.drivinglaws.org)​​ (SD Truck Info)​.

DUI Class Requirements

In South Dakota, first-time DUI offenders are typically required to complete a DUI education class, which can vary in length depending on the court’s specific requirements. The most common requirement is a 12-hour DUI education class. It’s important to note that online DUI classes are not recognized as fulfilling the state-mandated requirements for residents who committed their offense within South Dakota. Offenders must attend a local class approved by the state.

If you’re considering taking an online class because you received your DUI in another state or you are not a resident of South Dakota, you should first verify with the authority requiring the class to ensure that an online class would be accepted​ (DUI Law Center)​​ (DUI Process)​.

Driver License Hearing

In South Dakota, if you’re a first-time DUI offender, you’re required to attend a driver license hearing.

The hearing itself is conducted by the Secretary of the Department of Public Safety, and it is your opportunity to present reasons why your driving privileges should not be suspended or revoked​ (DMV.ORG)​.
