  2. Come to a complete stop Correct answer.
  3. Proceed only when the light turns green

  1. A school crossing
  2. A railroad crossing ahead
  3. A divided highway begins

  1. Stop, unless you are too close to stop safely Correct answer.
  2. Speed up to clear the intersection

  1. Drive through without looking for pedestrians
  2. Enter only if you are turning right
  3. Proceed straight or turn, yielding to pedestrians and vehicles already in the intersection Correct answer.

  1. You may turn left after yielding to oncoming traffic
  2. You must wait for the light to turn green

  1. A work zone
  2. A school zone or school crossing Correct answer.

  1. The vehicle on the right yields
  2. The vehicle traveling faster yields
