South Dakota Drunk Driving Laws

South Dakota law prohibits driving with a blood alcohol content (BAC) of .08%. It is also against the law to be under the influence of alcohol, drugs, or any substance to the extent that the driver is not capable of driving the vehicle safely.  

Having a valid prescription for a certain drug is not a defense to driving while under the influence of a prescription drug if it prevents them from being able to safely drive.

Implied Consent: Yes

Enhanced Penalties: BAC of .17% or more; child present in the vehicle; an accident causing serious bodily injury or death; previous convictions within ten years

The BAC is .02% if you are a driver under the age of 21 years old and on a first offense of this type you can face a 30-day license revocation for a first offense, 180 days for a second offense, and 1 year any third or subsequent offense.

The typical penalties you may face in South Dakota for a drunk driving offense include the following:

First offense is a Class 1 Misdemeanor: Driver’s license suspension of 30 days to up to one year. Drivers may qualify for a restricted license to get to their job but will be subject to 24/7 sobriety testing.

Second offense is a Class 1 Misdemeanor: Driver’s license suspension of not less than one year. If you drive during a period when your license is revoked, you could face mandatory jail time of 3 days.

Third offense is a Class 6 Felony: Driver’s license suspension of one year. If you drive during the license suspension period, you can face a mandatory minimum of 10 days in jail.
