Remember to also watch for supplementary plates that might alter this priority rule.
Mastering Belgian road sign B17 is crucial for safe navigation and passing your theory test. This sign specifically signals an intersection where you must yield to traffic approaching from your right, a key aspect of Belgian traffic rules.
Belgian road sign B17, titled "Intersection with priority to the right", belongs to the belgian priority signs group. It is used to communicate intersection with priority to the right in a form that drivers can recognise quickly during Belgian theory study and real traffic. The practical task is to identify who must go first, who must wait, and whether the priority changes after the junction or narrow passage, because the legal effect of a road sign starts from its placement and can be refined by panels, lane markings, traffic lights, or zone signs. For learners, the safest approach is to identify the sign early, say what road users or manoeuvres it affects, and then choose speed, position, and priority behaviour that match the displayed instruction.
Belgian road sign B17 means "Intersection with priority to the right". In practice, it tells drivers to apply the priority instruction before entering the conflict point, while checking the exact road layout, markings, and any supplementary panels before acting.

The B17 sign signifies an intersection where the 'priority to the right' rule applies. This means you must generally yield to vehicles approaching from your right. It's crucial to identify this sign early and prepare to let other road users go first.
You must yield or stop when you see the B17 sign and there is traffic approaching from your right that would have priority. You should only proceed when it's safe to do so and you won't force other road users to brake or change their course.
Yes, while the B17 sign establishes the general priority to the right rule, supplementary panels or other traffic controls like traffic lights, road markings, or other signs can modify this. Always check for these additional instructions before deciding who has priority.
A common trap is assuming the priority rule applies universally without checking for supplementary panels. Learners might also forget that this rule applies even if the road to your right looks like a minor path, or if they are turning and the straight-ahead traffic technically has priority from the right.
Unlike signs that explicitly grant you priority (like a yellow diamond), the B17 sign reminds you of the general legal rule 'priority to the right'. Other priority signs might indicate a mandatory stop (B13) or give way (B15) situation, or establish priority on a main road (B11).
The safest approach is to reduce your speed well in advance of the intersection. Scan for vehicles on your right, and also check for cyclists or pedestrians who may not be as visible or might misunderstand priority rules. Only enter the intersection when you are certain it is safe.
