What should you do when approaching a stationary emergency vehicle on a highway containing at least four lanes, with at least two lanes proceeding in your direction of travel?

• Flash your headlights to alert the driver of your presence.
• Honk your horn and try to proceed past that vehicle with enough speed.
• Slow down and move into a lane that is not adjacent to the vehicle.
  Explanation:

  "When you see stationary utility, construction, maintenance, recovery, survey, or solid waste vehicles with flashing amber lights, you should slow down and move to a lane that is not next to the vehicle if it is safe to do so. On highways with at least four lanes, with two lanes going in your direction, you must slow down and move to a lane that is not next to the vehicle if it is safe to do so."
• None of the above.
