What is recognized as the least safe turn?

The least safe turn among the options given is a Y Turn. This maneuver requires a driver to make more complex adjustments to their vehicle's path compared to the other types of turns, often involving moving from one lane to another to make two distinct changes in direction. The nature of a Y Turn can lead to confusion and increases the potential for collisions because of the multiple lanes being crossed and the need for careful observation of surrounding traffic.

In contrast, a U Turn, while generally considered dangerous due to the need to cross oncoming traffic, is typically a one-time movement that can be planned and executed with full visibility. A right turn tends to be safer than both a Y Turn and a U Turn because it is usually done from a dedicated lane and involves fewer conflicts with oncoming vehicles. A left turn can also be risky but is often done at intersections with dedicated left turn signals, which mitigates some of the risks involved.

Thus, the complexity and potential for conflict inherent in a Y Turn contributes to its classification as the least safe turning maneuver among the given choices.
