What does this traffic light indicate?

• Drivers must prepare to stop or clear the intersection if already in it.
  Explanation:

  "A solid red traffic light means drivers must come to a complete stop at the stop line or before entering the intersection. If a driver is already in the intersection when the light turns red, they must clear the intersection safely. Drivers must not proceed until the light turns green (except for permitted right turns after stopping and yielding)."
• Drivers must come to a complete stop and only proceed when safe.
• Drivers can proceed through the intersection without stopping.
• Drivers can only turn right at the intersection.
