Under what conditions are U-turns legal within city limits?

U-turns can be legal within city limits under specific conditions that ensure the safety of the driver and other road users. When evaluating the options provided:

• A U-turn is permissible if the road is clear and there is sufficient time to safely execute the maneuver. This ensures that the driver can complete the turn without interfering with the flow of traffic.

• The presence of a broken line signifies that lane changes and U-turns are allowed, which provides a visual cue that the maneuver can be performed legally in those designated areas.

• If there are no prohibiting signs present, it indicates that local traffic regulations do not restrict U-turns at that location. Absence of such signs means drivers have the green light to make the turn provided they do so safely.

Combining these conditions, a U-turn is legally permissible within city limits when the road is clear, the lane markings allow for such a maneuver, and no signs discourage the action. Therefore, it is accurate to state that all of these conditions must be met for a U-turn to be considered legal.
