What is a U-turn?

A U-turn, known as a "U-vending" in Danish, is a maneuver performed by a driver to completely reverse the direction of their vehicle. This typically involves turning 180 degrees to proceed in the opposite lane of traffic. While seemingly straightforward, U-turns require significant space and careful judgment to ensure they are carried out without creating danger or impeding other road users. It's a maneuver often considered when a driver has taken a wrong turn or needs to return to a previous location.

When are U-turns Permitted in Denmark?

In Denmark, U-turns are generally permitted where there are no specific signs prohibiting them, and where it can be done safely without obstructing or endangering other traffic. This usually means wide, clear roads with good visibility, often in less congested areas. Before attempting a U-turn, a driver must always assess the road conditions, traffic density, and available space. Key considerations include ensuring there is enough clear road ahead and behind to complete the turn smoothly and without causing other drivers to brake or swerve.

Where are U-turns Forbidden?

It is crucial for Danish driving theory learners to know where U-turns are explicitly forbidden. Performing a U-turn in prohibited areas can lead to immediate danger and legal consequences. In Denmark, U-turns are strictly forbidden in the following situations:

• Where signs prohibit them: Look for road signs indicating "No U-turn" (often a U-shaped arrow with a red diagonal line through it).
• At intersections with traffic lights: U-turns are generally not allowed at signalized intersections due to the complex traffic flow and potential for collision.
• Where there is a solid double white line or barrier: These road markings indicate that crossing is prohibited, including for U-turns.
• If it would obstruct or endanger other traffic: Even if not explicitly signed, a U-turn is illegal if it forces other drivers to take evasive action, creates a hazard, or significantly holds up traffic flow.
• On motorways (motorveje): U-turns are strictly prohibited on motorways, including their entrance and exit ramps.

Performing a U-turn Safely

Executing a U-turn safely requires excellent observation and vehicle control. Before initiating the turn, check your mirrors and blind spots thoroughly. Signal your intention well in advance. Position your vehicle to maximize turning radius, often by moving to the far left (if safe and permitted) before turning sharply right. The maneuver should be completed as quickly and smoothly as possible, ensuring you maintain control of the vehicle at all times. Always prioritize waiting for a clear gap in traffic rather than rushing the turn and creating a hazardous situation.

U-turns in the Danish Driving Theory Exam

Questions about U-turns frequently appear in the Danish driving theory exam. These questions often test your knowledge of prohibited areas, correct signaling, and safe execution. You might be shown an image of a road scenario and asked whether a U-turn is permitted or what the correct action would be. It's vital to remember the specific prohibitions, especially regarding signs, traffic lights, and obstructing other traffic, as these are common areas of misunderstanding.
