Understanding DUI/DWI Penalties
There are four main factors that determine the severity of the penalties incurred:
- The age of the driver
- The substance impairing you. This may be drugs, or alcohol, or both
- The category of your driver’s license (Restricted, CDL)
- Whether you refused a chemical test
Chemical Test Refusal
– Every state has some version of the “Implied Consent” law
– This law carries serious consequences for refusing a chemical test
– The penalties for refusing a chemical test in South Dakota are:
1st Refusal
- 1 year license suspension
2nd Refusal
- 1 year license suspension
3rd Refusal
- 1 year license suspension
Lookback Period
- In South Dakota the lookback period is 10 years
- Any arrest for DUI/DWI within 10 years of your first offense results in higher penalties
Zero Tolerance
- Drivers under 21 with a BAC of .02% or more will be charged with DUI/DWI
- A BAC of .08% and above will result in the same penalties as drivers 21 and over
Penalties for Underage Drivers (under 21)
DUI/DWI Penalties/Alcohol/Drug related (Non-Aggravated)

- $2000 fine
- Prison (1 year maximum)
2nd Offense

DUI/DWI Penalties/Alcohol/Drug related (Aggravated)
- There are no set guidelines for Aggravated DUI/DWI penalties in South Dakota
- It is generally understood that the penalties will be harsher, but the exact figures are at the discretion of the judge
- The most significant difference is that a charge of Aggravated DUI/DWI makes it mandatory for you to be evaluated by a state approved mental health and substance abuse counselor
CDL Drivers (Commercial)
- Those with a commercial driver’s license (CDL) are held to a stricter standard
- The BAC threshold is significantly lower (0.04%), and the penalties incurred are often much more severe
- An initial DUI conviction in a passenger or commercial vehicle will result in a one year CDL suspension
- A second DUI conviction in a passenger or commercial vehicle will result in a permanently revoked CDL
SR-22 Insurance Requirements
- SR-22 Insurance is a requirement in many states as a condition of restoring your driving privileges
- Most, but not all states have SR-22 statutes
- In South Dakota an SR-22 must be filed with the Department of Motor Vehicles (DMV) before your driving privileges can be restored
- You must maintain your SR-22 for a period of 3 years following the restoration of your driving privileges
- Should you lapse at any point, your insurance company will inform the DMV and your license will be revoked
Wet Reckless
- Wet Reckless is a general term that refers to a plea bargain that may reduce the severity of the charge against you
- South Dakota does allow for plea bargains in DUI/DWI cases
- It can only be pleaded down to reckless driving
- This allows you to avoid a criminal record
- Any subsequent DUI/DWI arrests within the look-back period will reverse the original plea bargain
- The reckless driving will revert back to a full DUI/DWI conviction and lead to enhanced penalties in this case
- This plea bargain is typically only allowed for first time offenders with no aggravating factors involved
