Under what condition is it not allowed to turn a vehicle to move in the opposite direction?

Turning a vehicle to move in the opposite direction is not allowed when approaching a curve or crest of a grade where visibility is obstructed. This rule is in place to ensure safety, as such areas typically present a higher risk of collision. The inability to see oncoming traffic clearly increases the chances of an accident if a driver attempts to make a turn in those situations.

In circumstances where visibility is limited due to the curvature of the road or the incline of a hill, other drivers may not have enough time to react if they suddenly encounter a vehicle making a turn. This regulation aims to promote safe driving practices by minimizing the potential for dangerous situations where the driver is unable to fully assess the conditions around them before making the maneuver.

Safe turning practices are essential for maintaining traffic flow and protecting all road users, which underscores the importance of adhering to regulations regarding turning in areas with visibility issues.
