After a crash, which information should the involved drivers exchange according to the handbook?
Correct answer: Names and addresses, driver-license and registration information, and insurance information.
The handbook calls for exchanging driver, vehicle and insurance identification. Photographs or a repair estimate do not replace that information.

What blood-alcohol concentration meets South Dakota's per-se alcohol prohibition for an ordinary adult car driver?
Correct answer: 0.08% or more.
The ordinary per-se threshold is 0.08%. Impairment can still violate the law below that number; it is not a safe-drinking target.

An adult driver is stopped temporarily at a red light and opens a social-media feed. Is that outside South Dakota's driving-device prohibition merely because the car is stopped?
Correct answer: No; a traffic-light stop still counts as operating, and accessing social media is prohibited.
The definition includes temporary stops caused by traffic or traffic controls. The separate social-network rule prohibits accessing, reading or posting while operating.

Under current South Dakota DSS safety guidance, when should a young child move from rear-facing to forward-facing?
Correct answer: After reaching the rear-facing height or weight limit allowed by the seat manufacturer.
DSS recommends remaining rear-facing as long as the seat's height and weight limits allow. The handbook's old nine-month conversion wording is not used.

A 16-year-old rides in the back seat of an ordinary car. Does sitting in the rear remove South Dakota's restraint requirement for that passenger?
Correct answer: No; occupants under 18 must be properly restrained in all seating positions.
DSS states that all occupants age 17 and younger must be buckled up. The rear-seat position does not create an exemption for a minor.

You hold a valid South Dakota operator license and plan to drive. What does the immediate-possession rule require?
Correct answer: Have your driver license in your immediate possession while operating the vehicle.
A licensee must have the driver license in immediate possession while operating a motor vehicle and display it on a lawful demand. Merely having a valid record or memorizing the number does not satisfy that possession rule.
