The D-3 road sign, a blue rectangle with a prominent white arrow, is an information sign indicating that traffic on the road or lane ahead moves in a single, specified direction. Drivers must adhere to the direction shown by the arrow to ensure traffic flow and safety, especially in busy urban areas. If you encounter this sign, remember that driving against the arrow is prohibited for most vehicles, although cyclists might have exceptions with supplementary plates.
This sign confirms that all traffic must move in the direction specified by the arrow, crucial for safe urban navigation and your theory test revision. Mastering road sign meaning is key to understanding traffic flow and avoiding violations.
The D-3 sign indicates a street where vehicular traffic is legally restricted to move in a single direction. It is a blue rectangular sign with a large white arrow pointing upward. This setup is common in dense urban centers to improve traffic flow and reduce head-on collision risks. If a T-22 supplementary plate is present, it indicates that bicycles are allowed to travel in the opposite direction (contraflow) on a designated lane.
Traffic on this road or lane moves in only one direction as indicated by the arrow.
Get clear, practical answers to the most common questions about the D-3 - One-Way Road road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations.

The D-3 sign, a blue rectangle with a white arrow, clearly indicates that traffic on that particular road or lane is restricted to only one direction. You must travel in the direction the arrow is pointing. This helps organize traffic and prevent head-on collisions.
When you see the D-3 sign, you must only drive in the direction shown by the white arrow. Driving or reversing against the direction of the arrow is prohibited and dangerous, unless you are a cyclist on a specially marked contraflow lane (indicated by a supplementary plate T-22).
Yes, while most vehicles must follow the arrow's direction, cyclists might be permitted to travel in the opposite direction on a designated lane if a supplementary plate (T-22) is present below the D-3 sign. Always check for such plates.
When making a left turn from a one-way street, you must position your vehicle at the far left edge of your lane before turning. This is a common maneuver on one-way roads and often tested in practical driving and the theory exam to ensure safe lane discipline.
Learners sometimes forget the rule about positioning for a left turn from a one-way street, or they overlook supplementary plates like the T-22 for cyclists. Understanding that 'one-way' applies strictly to the indicated direction, unless specific exceptions are clearly marked, is crucial.
