What should you do when facing a red flashing light at an intersection where all traffic must stop?

• Yield to vehicles already in the intersection
• Yield to vehicles that stopped before you
• Yield to vehicles that arrived at the same time as you
• All of the above
  Explanation:

  "If you are facing a red flashing light at an intersection where all traffic is required to stop, you may proceed after you have stopped and yielded the right of way to any vehicle that is already in the intersection, any vehicle that stopped before you and is entering the intersection, and any vehicle that arrived at the same time as you and is to your right."
