Final answer:
The maneuver to turn around when the road is too narrow is called a three-point turn.
Step-by-step explanation:
When the road or street is too narrow to make a U-turn and you cannot go around the block, the maneuver to turn around is called a three-point turn or a three-point turnabout. A three-point turn is a technique used to reverse the direction of your vehicle by making three separate movements - one to the left or right, one forward, and one final turn to complete the turn. This is typically done by backing into a driveway or pulling into a safe space on the opposite side of the road.
For example, imagine you are driving on a narrow one-way street and need to turn around. You cannot make a U-turn due to the size of the road, and there are no alternative routes. In this situation, you would perform a three-point turn to safely reverse your direction and continue your journey.
