What do you do when you first see a flashing yellow signal light?

  1. Stop and wait

  2. Increase your speed

  3. Slow down and proceed with caution

  4. Speed up and pass

The correct answer is: Slow down and proceed with caution

When you approach a flashing yellow signal light, it indicates that you should proceed with caution. This means that you should slow down and be prepared to stop if necessary. Option A is incorrect because stopping is usually only necessary at a solid yellow or red light. Option B is incorrect because increasing your speed can be dangerous if there are other vehicles or pedestrians nearby. Option D is incorrect because you should never speed up or pass when approaching a flashing yellow light, as it could potentially cause a collision with other vehicles or pedestrians.
