In a residential district, when is a U-turn permitted?

• A. Only at intersections on a green light.
• B. Across a double yellow line.
• C. If no vehicles approaching within 200 ft.
• D. If no vehicles approaching within 1000 ft.

Answer: (C)

In residential areas, a U-turn is allowed only when you can complete the maneuver without interfering with approaching traffic. The key safety factor is whether there’s a vehicle coming from the opposite direction within a short distance. If no vehicles are within 200 feet, you have enough time and space to finish the turn safely. If a vehicle is within 200 feet, you should not attempt the U-turn because it could force that vehicle to slow or swerve.

Why the other ideas don’t fit: crossing a double yellow line is typically not allowed for a U-turn; relying on a green light at an intersection doesn’t guarantee it's safe or allowed; and waiting for 1000 feet isn’t the standard distance used to permit a U-turn.
