Are you allowed to make a U-turn on a roadway with this sign?

Correct answer: NO

🔍 Situation analysis: From a driver's perspective, you are moving along a road where a vertical sign has been placed. This is sign D-3, which is a characteristic blue rectangle with a large white arrow pointing up. It indicates entry onto a one-way road or roadway. The question checks whether you have the right to perform a U-turn on such a section.

📖 Rule explanation: The answer is "No". Traffic regulations explicitly list places where U-turning is strictly forbidden. These include, among others, a one-way road. This rule is dictated by basic safety – if you were to turn around in such a place, you would automatically start moving "against the flow," heading straight for a head-on collision with other drivers who do not expect a vehicle coming from the opposite direction.

⚖️ Legal basis: Art. 22 sec. 6 point 4 of the Road Traffic Act.

💡 Tip: In the practical exam, students very often confuse the shapes of blue signs. The rectangular D-3 sign ("one-way road") informs you about how traffic is organized – it allows you to turn left and right at intersections, but absolutely forbids U-turns. Do not confuse it with the circular C-5 sign ("mandatory straight ahead"), which forbids any turns. Breaking this rule on a one-way road is a so-called critical error – the examiner will intervene using the brake, which will result in a negative score. Watch the signs!
