U-turns are prohibited at which of the following locations?

• A. Intersections
• B. Two-lane highway
• C. Curves
• D. Four lane city street

Answer: (C)

U-turns are prohibited at curves primarily because they can create significant hazards for both the driver attempting the maneuver and other road users. In curves, visibility is often limited, which increases the risk of accidents. A vehicle making a U-turn can suddenly appear in the path of oncoming traffic that may not have a clear line of sight to the maneuver, leading to unsafe conditions.

While U-turns can also be restricted in other locations such as intersections or on two-lane highways, these areas might allow for U-turns if the conditions are safe and no signage prohibits the action. However, curves inherently offer less visibility and more unpredictable driving conditions, making them particularly dangerous for such maneuvers. Thus, prohibiting U-turns in these areas is a safety measure aimed at reducing the risk of collisions.
