When is it safe to return to your lane after passing a vehicle?

• When the driver you passed slows down to let you return to your lane
• When you are at least 50 feet ahead of the vehicle you passed
• When you can see the tires of the vehicle you just passed in your rearview mirror
  Explanation:

  "Do not return to the right side of the road until you can see the tires of the vehicle you passed in your rear-view mirror. Signal when you are about to return to your lane."
• Only after you have put your turn signal on
