Under what conditions is a U-turn allowed?

• A. When there is no sign prohibiting it.
• B. When not prohibited by signs and when it can be completed safely without impeding traffic.
• C. Only on highways.
• D. Never.

Answer: (B)

U-turns are allowed only when there is no sign prohibiting them and you can complete the maneuver safely without impeding traffic. This means you must have a clear view of oncoming vehicles, enough space in your lane to turn without crossing into opposing traffic, and no signs or road markings that forbid the turn. Even if there’s no sign, performing a U-turn in heavy traffic, on a hill or blind curve, or where it would cause others to slow or brake abruptly isn’t safe and isn’t allowed. On highways, U-turns are generally not permitted, so use a proper exit or turnaround instead.
