Grünpfeil

Grünpfeil, in German traffic terminology, refers to a traffic sign and the associated rule that allows a vehicle to proceed in a specified direction on a red light at signal-controlled intersections after coming to a full stop and ensuring the way is clear. The sign shows a green arrow in the direction of travel and is used in combination with standard red signals. The allowed direction is always indicated by the arrow (for example, Grünpfeil rechts for right turns, Grünpfeil geradeaus for straight-ahead movement), and the exact conditions are defined by accompanying signs.

The Grünpfeil is employed in several European countries, notably Germany and Austria, as a means to reduce delays at busy intersections while maintaining safety. Its use is typically restricted to intersections where special traffic control has been implemented and where a clear view of cross traffic and pedestrians can be maintained. The general principle is that a driver must stop completely at the stop line, yield to pedestrians and opposing traffic, and only proceed in the indicated direction when the maneuver can be performed safely.

Variants and scope vary by country and municipality. Some jurisdictions require additional signaling or specific times for Grünpfeil permissions, while others rely on signage at the approach to designate where the rule applies. In all cases, drivers must not use the Grünpfeil if the path is blocked or if another signal prohibits the turn.

As with many traffic signs, local regulations govern the precise application of Grünpfeil, and motorists should consult the relevant national or regional road traffic laws for exact details.
