Question

You are driving on a public road and need to turn your vehicle around you can use a three-point turn

Answer 1

Depending on how big or small the road is that you're using. If the road is small, you can use a 3-point turn, and if its big, you could probably do a full u-turn. Therefore, you can do a three point turn on a public road--IF a u-turn is allowed on that road.
