  1. Ask the officer for identification
  2. Refuse to interact until a marked unit arrives
  3. Step out of the vehicle immediately to speak with them
  4. Drive to the nearest police station before stopping

Answer: A — Ask the officer for identification

A non-uniformed officer in an unmarked car should be asked for identification before the driver proceeds.

2. A traffic signal at an intersection is completely dark due to a power outage. How should drivers treat the intersection?

  1. As a yield-only intersection for all directions
  2. As a four-way stop
  3. As having no right-of-way rules at all
  4. As reserved for the road with more lanes

Answer: B — As a four-way stop

A non-working signal turns the intersection into an all-way (four-way) stop.

3. A driver increases speed from 30 mph to 35 mph before a frontal collision. How does the impact change?

  1. It is about the same
  2. It is roughly a third more violent
  3. It is twice as violent
  4. It becomes survivable regardless of impact type

Answer: B — It is roughly a third more violent

A frontal impact at 35 mph is about a third more violent than at 30 mph.

4. A driver travels 55 mph, at the posted limit, during a snowstorm and crashes. Can they be cited for speed?

  1. Yes, but only if another vehicle was also speeding
  2. Yes, because posted limits assume ideal conditions and speed must suit conditions
  3. No, because they did not exceed the posted maximum
  4. No, because citations only apply above the posted limit

Answer: B — Yes, because posted limits assume ideal conditions and speed must suit conditions

Limits are set for ideal conditions, so a driver can be cited for driving too fast for conditions even at or below the posted limit.

5. On a divided highway, when may a driver cross the median or barrier?

  1. Only to pass a slower vehicle
  2. Anywhere it looks clear of traffic

If a driver cannot see at least a quarter mile ahead, they should not pass.

7. A driver notices another vehicle sitting in their blind spot while they want to change lanes. What is the correct response?

  1. Flash their turn signal at the other driver to signal them to pass
  2. Speed up or slow down until there is room
  3. Stop in the lane until the other car passes
  4. Force their way into the lane since they have the right-of-way

Answer: B — Speed up or slow down until there is room

With a car in the blind spot, the driver should speed up or slow down until there is room, never forcing their way in.

10. A school bus stops to load children on a four-lane road that has no barrier or median separating the directions. Must an oncoming driver on the other side stop?

  1. No, because it is a four-lane road
  2. Yes, but only if the road has five lanes
  3. No, only vehicles behind the bus must stop
  4. Yes, because there is no barrier separating the roadway

Answer: D — Yes, because there is no barrier separating the roadway

Drivers must stop on a four-lane road without a barrier when a school bus is stopped.

11. A school bus is stopped across a dedicated two-way left-turn lane on a four-lane road, loading children on the far side. Must a driver on the near side stop?

  1. No, a two-way left-turn lane separating the roadway means the driver need not stop
  2. No, but only if the bus is completely off the road
  3. Yes, unless the bus has its stop sign folded away
  4. Yes, all drivers on any road must always stop

Answer: A — No, a two-way left-turn lane separating the roadway means the driver need not stop

Drivers need not stop when the bus is on the opposite side of a four- or five-lane road separated by a dedicated two-way left-turn lane.

  3. No, right turns should be made from the left-most lane
  4. Yes, but only on multi-lane roads

Answer: A — No, a right turn should be made without swinging left first

A right turn should not involve swinging left first, and should be made from the right-most lane.

14. Two drivers approach an intersection from opposite directions, both signaling to turn left. How should they complete their turns?

  1. They should each wait for a traffic signal before proceeding
  2. Whichever driver arrived first turns first while the other waits
  3. Each should turn to the right of the center of the intersection
