The B1 sign, a yellow diamond with a white border, indicates that you are on a priority road and have right of way at upcoming intersections. This applies until you see an 'End of Priority Road' sign (B2) or another sign changes the priority rules. These signs are commonly used outside built-up areas to maintain a smooth flow of traffic on main routes, ensuring you can proceed with caution while expecting others to yield.
Learn the key details of the B1 - Priority Road road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in the Netherlands. Use this overview to understand the sign clearly and recognise it confidently during the Dutch driving theory exam.
A yellow diamond with a white border marks a priority road on which vehicles have priority over traffic from intersecting roads, unless other signs or markings indicate otherwise. The rule continues until an End of Priority Road sign or a new priority arrangement appears. It is commonly used on through roads to maintain a steady, predictable traffic flow.
This sign tells you that the road you are on is a priority road where your traffic generally has right of way at upcoming intersections. Other roads that join or cross this road must usually yield, although you must still adapt your speed and watch carefully for vulnerable road users.
Get clear, practical answers to the most common questions about the B1 - Priority Road 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 Dutch driving theory exam in the Netherlands.
The B1 sign confirms that you are on a priority road and therefore have the right of way at all subsequent intersections until this priority is cancelled. You should expect traffic from side roads to yield to you.
The priority granted by the B1 sign continues until you encounter a sign that cancels it, most commonly the 'End of Priority Road' sign (B2). It can also be superseded by other signs indicating a different priority rule, such as a give way or stop sign.
When you see a B1 sign, you generally have the right of way. However, you must still approach intersections with caution, be aware of other road users, and be prepared to react if necessary, even though you are on the priority route.
A common mistake is assuming priority is absolute and not checking intersections, especially if there's no immediate traffic visible. Learners might also forget that the priority ends when a B2 sign appears or another priority rule is introduced. Always be observant.
Yes, although the B1 sign grants you priority, you must always drive defensively. If another road user enters the intersection without yielding, or in an emergency situation, you must still take appropriate action to avoid a collision. Priority does not mean you can ignore other traffic.
B1 signs are typically used on major through roads, often outside of built-up areas, to facilitate a continuous flow of traffic. They ensure that the main route is less interrupted by traffic joining from minor roads.
