The D4 sign, officially known as 'Mandatory Direction — Straight Ahead', is a crucial traffic sign used in the Netherlands. It dictates that you must proceed directly forward through the intersection or junction where it is displayed. This sign is often found at locations where turning is prohibited for safety reasons or because the road ahead is intended exclusively for through traffic. Drivers must comply with this directive to ensure safe traffic flow and avoid violating traffic rules.
This D4 sign mandates continuing straight, prohibiting turns. Grasping its meaning is crucial for safe Dutch driving and passing your theory test. Our detailed explanation covers its implications and proper recognition.
D4 is a blue mandatory direction sign with a single upward arrow, meaning that only straight-ahead movement is allowed. It is typically installed before intersections, junctions, or road forks where turning left or right would be unsafe, undesired, or reserved for specific users. The sign helps maintain smooth traffic flow on through routes and prevents conflicts with oncoming or crossing traffic at side roads that are not intended for general turning.
This sign requires drivers to continue straight ahead and forbids turning off the main direction at the next junction or split. It is used where side roads are not suitable for turning traffic or where through movement must be protected. When you see this sign, choose the correct lane in advance and follow the carriageway straight on without turning or making a U-turn.

The two arrows on the sign show the permitted movements, and all other directions, such as left turns or U-turns, are forbidden while the restriction applies.
