South Dakota Speed Limits

Speed limit questions are among the most commonly tested on the South Dakota DMV exam. The test will give you several close options — you need to know the exact number for your state, not just a rough estimate.
South Dakota DUI Laws
South Dakota uses the term DUI for impaired driving offenses. The legal blood alcohol concentration (BAC) limit is 0.08% for drivers 21 and older. For drivers under 21, South Dakota sets the limit at 0.02%.
Under South Dakota's implied consent law, by holding a driver's license you have already agreed to submit to chemical testing if an officer suspects impaired driving. Refusing a test typically results in an automatic license suspension — often longer than the penalty for a first-offense DUI.
