Numbers to know

3 questions from the South Dakota practice test

1. 1. When must you stop for a South Dakota school bus?

   1. Whenever its red lights flash or stop arm is extended unless a physical barrier separates the roadway
   2. Only when you are behind it on a two-lane road
   3. Only during posted school hours
   4. Only if children have already stepped into your lane
   Show answer

   Whenever its red lights flash or stop arm is extended unless a physical barrier separates the roadway. South Dakota requires stopping for a school bus with flashing red lights or an extended stop arm at all times unless a physical barrier separates the roadway. Limiting the rule to drivers behind the bus, to school hours, or to children already in your lane misses that it applies whenever the red lights flash or the arm is out. After the red lights stop flashing and the stop arm is no longer visible, proceed slowly while watching for children.

2. 2. A school crossing guard tells you to stop. What does South Dakota require?

   1. Stop only if the guard is holding a red sign
   2. Continue slowly unless children are already in the crosswalk
   3. Obey only traffic lights and posted signs
   4. Follow the guard's direction to stop
   Show answer

   Follow the guard's direction to stop. School crossing guards are included in South Dakota's traffic control devices, along with law enforcement and highway personnel. Their directions are not optional suggestions. The choice about continuing until children are already in the crosswalk reacts too late and ignores the guard's authority. When a person directing traffic faces your lane and signals stop, brake before the crossing and wait for a clear release.

3. 3. When passing horseback riders or animal-drawn vehicles, what should you avoid?

   1. Avoid leaving extra space
   2. Avoid slowing before you pass
   3. Avoid using the horn or revving the engine
   4. Avoid looking for driveway turns
   Show answer

   Avoid using the horn or revving the engine. Horses can be frightened by sudden noise, so South Dakota tells drivers not to honk or rev the engine near animal-drawn vehicles or riders. Avoiding extra space is the opposite of a cautious pass. Look for rural warning signs, fields, and driveways, then pass slowly and expect an animal-drawn vehicle to turn left. Extra patience is important because riders and animals can react unpredictably to sound, speed, or tight clearance.
