The D1 Mandatory Direction sign, a blue circular sign with a white arrow, tells you exactly which way you must go. You are only permitted to drive in the direction indicated by the arrow. If two arrows are shown, you may choose either of the specified directions, but no other. This sign is crucial for guiding traffic safely through junctions and complex road layouts, ensuring predictable flow for all road users.
This D1 Mandatory Direction sign requires drivers to strictly follow the arrow's indicated path, crucial for safe navigation and compliance with Swedish traffic rules. Mastering its meaning is vital for passing your theory test and understanding specific road sign explanations.
This sign is a blue circular mandatory sign with one (or sometimes two) white arrow(s). It requires drivers to follow the direction(s) indicated, meaning you are not permitted to continue straight, turn, or enter a different direction than the arrow allows. The arrow design may be adapted to match the exact layout of the junction or roadway. In practice, it is used at intersections, channelised junctions, and one-way guidance points to force a safe and orderly traffic flow.
You must drive only in the direction shown by the arrow. If two arrows are shown, you may drive in either of the indicated directions.
Get clear, practical answers to the most common questions about the D1 - Mandatory Direction road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Swedish driving theory exam in Sweden.
The D1 Mandatory Direction sign means you must drive only in the direction shown by the white arrow(s) on the sign. You are prohibited from going in any other direction, including straight ahead if the arrow indicates a turn.
If the D1 Mandatory Direction sign displays two arrows, it means you have a choice between the indicated directions. You must select one of these two allowed directions and cannot proceed in any other path.
No, you cannot go straight if the D1 sign shows a turn. The sign explicitly mandates that you must follow the direction indicated by the arrow. Going straight when the arrow points to a turn is a violation of this sign's instruction and is prohibited.
A common trap is assuming you can go straight if the arrow points sideways, or not paying attention to the exact direction shown. Learners might also miss that if there are two arrows, you must choose one of them, not ignore the sign altogether. Always look carefully at the arrow's placement and direction.
You'll typically encounter the D1 Mandatory Direction sign at junctions, channelised intersections, or before specific road configurations where traffic flow needs to be strictly controlled. It's used to ensure vehicles follow a predetermined, safe path.

This sign is a mandatory instruction telling drivers which side of an obstruction, island, refuge, or traffic separator they must pass. It is typically shown as a blue circular sign with a white arrow pointing left or right, and sometimes with two arrows indicating both sides are permitted. The symbol may be adapted to local conditions, reflecting the physical layout of the road feature. Legally, it prevents drivers from choosing an unsafe side that could cause conflicts with oncoming traffic or pedestrians near the island.
The Yellow Light Arrow device provides a highly visible instruction showing which side road users must pass. It is commonly used where an obstacle, work zone, or temporary traffic arrangement requires vehicles to be guided to one side. The illuminated arrows can be steady or flashing to draw attention, especially in darkness or poor visibility. The device is directive rather than advisory, meaning you are expected to follow the indicated passing side. It helps prevent head on conflicts and keeps traffic aligned with the safe route through restricted or diverted sections.
