Questions (3)

1. A lane change:
  1. Should be done quickly.
  2. Should be done slowly. ✓
  3. Should be done with a jerking motion.

Answer: B. Should be done slowly.

A lane change should be done slowly and smoothly, not quickly or with a jerking motion. The handbook's lane-change rule says to signal first and then move over slowly and smoothly. It gives a practical reason: if another driver is in a spot you missed, a gradual move gives that person time to sound the horn or get out of the way. That is why the slow, smooth approach is the one the test expects.
2. When you need to change lanes:
  1. Other vehicles will likely get out of your way.
  2. You should change lanes slowly and smoothly. ✓
  3. You should wait to change lanes until you are in an intersection.

Answer: B. You should change lanes slowly and smoothly.

3. When making a lane change, your turn signal:
  1. Should always be used. ✓
  2. Should only be used if there is traffic present.
  3. Should only be used between dusk and dawn.

Answer: A. Should always be used.

Your turn signal should always be used when you make a lane change. The handbook says to use turn signals properly, activate them when required and at appropriate times, and cancel them after completing a turn or lane change. It also describes using the turn signal as part of moving into the lane you need. Nothing in these passages makes signaling a lane change depend on traffic being present or on the time of day, so the signal is treated as a normal part of the lane change itself.
