Sample questions from this bank

Two real questions from the South Dakota set

These are pulled directly from the South Dakota question bank above, not invented for this page. In the practice test itself, the answer and explanation only show after you pick a choice.

Alcohol and DUI

South Dakota's 'Zero Tolerance' law for drivers under 21 sets the illegal BAC threshold at what level?

0.02%
0.08%
Any amount is legal as long as under 21 is not impaired

Show answer and explanation

0.02%. Unlike states that use 0.01% or an absolute zero standard, South Dakota sets the underage threshold at 0.02% BAC, well below the adult 0.08% level.

Laws and paperwork

Besides a standard auto liability insurance policy, which of the following is listed in South Dakota as an acceptable way to show financial responsibility?

A cash deposit or bond filed with the State Treasurer
A personal handwritten letter guaranteeing payment
A verbal agreement with the DMV clerk

Show answer and explanation

A cash deposit or bond filed with the State Treasurer. South Dakota allows several alternatives to a standard insurance policy, including a cash deposit or securities bond with the State Treasurer, a surety bond, or self-insurance for large fleets.
