When are you allowed to make a U-turn?

Making a U-turn is permissible when there are no signs prohibiting the action, and it is safe to do so. This means that before attempting a U-turn, a driver should carefully assess the situation to ensure there is enough space, that visibility is clear, and that no vehicles or pedestrians are at risk. It's important to be aware of local traffic laws, which may set specific rules about U-turns, and to look for signs indicating whether U-turns are allowed.

In contrast to other options: traffic lights regulate vehicle movement but do not directly dictate U-turn legality; U-turns are generally not restricted to only one-way streets; and while they can be made at intersections, the overall safety and absence of prohibitive signage are crucial factors to consider.
