The B4 sign signals the start of a priority road, meaning traffic joining from side roads must usually yield to you. It's crucial to understand this sign as it defines your right of way at upcoming intersections. While you generally have priority, always drive defensively, remain aware of other road users, and be prepared to adjust your speed or brake if necessary, especially in adverse conditions or if another driver fails to yield.
Learn the key details of the B4 - Priority Road Begins road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in Sweden. Use this overview to understand the sign clearly and recognise it confidently during the Swedish driving theory exam.
This sign indicates the start of a road where you generally have priority at intersections, unless another sign or traffic control states otherwise. It is placed at the beginning of the priority road and repeated after intersections to confirm that the priority status continues. The purpose is to create a predictable flow on main routes and reduce uncertainty at junctions. Even with priority, you must still drive defensively, watch for errors by others, and adjust to conditions such as poor visibility, slippery roads, or pedestrians and cyclists.
You are entering a priority road, and traffic joining from side roads must normally yield to you at intersections.
Get clear, practical answers to the most common questions about the B4 - Priority Road Begins 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.
When you see the B4 sign, you are entering a road where you typically have priority over traffic on intersecting side roads. This means other drivers should wait for you to pass before they enter the priority road. The sign is placed to ensure smoother traffic flow on main routes.
Generally, yes, the B4 sign grants you priority. However, this priority can be overridden. Always be vigilant for traffic lights, police directing traffic, temporary road works, or explicit 'Yield' (V2) or 'Stop' (B1) signs at junctions, which take precedence over the B4 sign's indication.
Upon seeing the B4 sign, you can continue with the expectation of priority. However, you must still drive cautiously, scan side roads for approaching vehicles, and be ready to brake if another driver makes a mistake or doesn't yield. Never assume other drivers will always act correctly.
A common trap is assuming you have absolute priority and becoming complacent. Learners sometimes forget that other drivers might not see them, might misjudge speed, or might be experiencing poor visibility. Always be prepared to yield if a conflict is imminent, and remember that vulnerable road users like cyclists or pedestrians might behave unpredictably near junctions.
If the B4 sign is repeated after an intersection, it confirms that the priority road continues. This is common practice to reinforce your right of way, especially if there was a possibility of confusion or if side roads joined shortly after the initial sign. It reassures you that you still hold priority.
