What is the proper technique for teaching a student a three-point turn?

1. Have the student perform the maneuver at normal traffic speed without stopping in a licensed driving-school program — a three-point turn requires traffic checks at each forward and reverse step.
2. Teach them to check for traffic in both directions, signal, turn sharply into the opposite lane, reverse, and complete the turn
3. Only teach this maneuver on a multi-lane highway with a wide shoulder
4. Tell the student to make a U-turn instead of practicing a three-point turn
