3 questions from the South Dakota practice test
1. When must you stop for a South Dakota school bus?
- Whenever its red lights flash or stop arm is extended unless a physical barrier separates the roadway
- Only when you are behind it on a two-lane road
- Only during posted school hours
- 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 unless a physical barrier separates the roadway. Limiting the rule to drivers behind the bus misses traffic approaching from other directions. Use the red lights and visible stop arm as the cue, then proceed slowly after they end. Children may appear from the front or rear of the bus, so keep watching beyond the bus itself.
2. A school crossing guard tells you to stop. What does South Dakota require?
- Stop only if the guard is holding a red sign
- Continue slowly unless children are already in the crosswalk
- Obey only traffic lights and posted signs
- 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. Why does the South Dakota manual tell drivers to be especially watchful for bicyclists at night?
- Bicyclists are required to ride on the sidewalk after dark
- Some bikes may not have the reflectors or lights they should have
- Bicycles are not allowed on roads at night
- Bicycle lights are always bright enough to be seen
Show answer
Some bikes may not have the reflectors or lights they should have. Bicyclists should have reflectors or lights on their bikes, but the manual warns that some bikes may not have this equipment, so drivers must be especially careful and watchful for bikes and bicyclists. A rider with no lights can be invisible until the last moment. Slow down when approaching, pass with room, and remember that bicyclists have the same rights on the roadway as other vehicles. They are not required to leave the road at night.
