Priority to the right in Belgium, explained for newcomers

At a Belgian junction with no signs, no road markings and no traffic lights, one rule decides who goes first: you give way to every driver coming from your right. It does not matter who arrived first, which road is wider, or that you are going straight ahead. If a driver is approaching from your right, you let them go.

If you learned to drive in a country where the bigger road wins, or where “first come, first served” settles an unmarked crossing, this rule takes some unlearning. It is also one of the topics that can end your theory exam on its own. So it is worth getting right, calmly, before you book.

Facts checked on 8 October 2026 against the Belgian traffic code as taught in the Examula priority topic. The rules are being renewed in 2027, so reconfirm before your exam.

What the rule actually says

The rule is a fallback. It exists because two small streets may never be busy enough to justify a sign or a light, and they still need an answer both drivers already carry. “The one on my right goes first” is that answer. It is short, it is the same for everyone, and it works in the dark and in the rain.

The traffic code (article 12.3.1) writes down two exceptions. The rule does not apply to a driver who is already on a roundabout. And it does not apply to a driver who comes from your right out of a direction they are not allowed to use, such as against the flow of a one-way street. A vehicle that should not be there does not collect priority by being there.

The same article adds two situations where you give way to everyone on the road you are joining, from the left as well as from the right. The first is when you come out of a road that carries a give-way sign (B1) or a stop sign (B5). The second is when you come off an unsurfaced track or a footpath onto a road with a proper carriageway. In both cases the right-hand rule is not the question to ask. You are joining, so you wait for the whole road.

Giving way means more than slowing down

This is the part the exam tests most often, and the part learners from other countries most often miss. Article 12.5 says a driver who must give way may only drive on if they can do so without danger, taking into account where the other road users are, how fast they are going and how far away they are.

So the test is not whether you got through. It is whether anyone had to brake, swerve or stop because of you. If they did, you did not give way.

One more sentence sits just above the rule and is often skipped. Article 12.2 asks every driver entering an intersection to be doubly careful. Priority tells you who is expected to go. Double caution is what you do while you find out whether the other driver has read the junction the same way you have.

What overrides it, in a fixed order

Priority to the right applies only when nothing else governs the junction. Article 6 puts the things that override it in a fixed order:

1. A police officer or other authorised person directing traffic comes first and overrides everything else.
2. Traffic lights come next, and override signs and road markings.
3. Priority signs come next: B1 give way, B5 stop, B9 priority road, B11 end of priority road, B15 priority at this crossing, B17 priority to the right applies here.
4. Road markings come next, such as a give-way line of white triangles across your lane.
5. Priority to the right applies only when none of the above is present.

Read the junction from the top of that list down. As soon as you find something that decides it, you stop reading. An officer waving you on beats a red light. A red light beats a priority-road sign.

Where traffic lights are working, the priority signs standing on the same road do not apply at all (article 6.3). A yellow diamond next to a red light gives you nothing. The light decides, and the sign is asleep for as long as the light is awake. The flashing amber light is the exception worth learning: it is not a phase of a working light. You may pass it with double caution, and it does not change the priority arrangement. So at a junction on flashing amber, or where the lights are dark or out of order, you go back to reading the signs, and if there are none, back to the right-hand rule.

The habit to build is a question, asked in that order, before you decide anything. Is anyone directing traffic? Are there lights, and are they working? Is there a sign facing me? Are there markings on my lane? Only when all four answers are no does priority to the right decide the junction.

The signs that switch it off, and the one that confirms it

Four priority signs do most of the work in exam questions.

• B1, give way, the inverted triangle, and B5, stop, the octagon, both take priority away from you at the next junction. With B5, slowing down is not enough: you stop, then give way.
• B9, priority road, the yellow diamond, gives you priority at every junction along the road until B11, end of priority road, takes it away again.
• B17, crossroads where priority to the right applies, does not change anything. It confirms the default rule at a junction where drivers might otherwise assume they are protected.

The B11 mistake is worth a moment on its own. The end-of-priority sign does not hand priority to anyone else. It simply removes the protection you were carrying, so from there on the ordinary rules decide, which at an unsigned crossroads means the driver on your right goes first. Drivers who have been on a priority road for several kilometres are the ones who miss it.

A sign only speaks to the road it faces. A give-way sign on the side road protects you on the main road; a give-way sign facing you does not care what the side road has.

Where the rule does not reach

Roundabouts. Once you are on the ring, a car waiting at an entrance on your right does not have priority over you. At the entrance you will normally find a give-way sign together with the round blue roundabout sign, and that sign, not the right-hand rule, is what makes you give way to the traffic already going round. Entering a roundabout is the one change of direction where you do not indicate; leaving it, you do.

Turning across traffic. Turning does not create priority. When you turn left you cross the path of the oncoming traffic, and that traffic keeps its priority on the road you are leaving (article 19.3). You wait for a gap that does not make anyone slow down.

Manoeuvres. Article 12.4 lists them: changing lane, crossing the carriageway, leaving or entering a parking space, coming out of a property, turning the car around, and reversing. A driver performing one of these gives way to every other road user, from the left as well as from the right. Coming out of your own driveway onto a street, you are last, whatever side anyone is on.

Trams. Rail vehicles have priority over every other road user (article 12.1). A tram coming from your left still goes first, and a tram crossing the priority road you are on still goes first. There is no sign on your road that changes it.

Buses leaving a stop. Inside a built-up area, a driver going the same way as a bus must let it pull out of its stop once it has signalled (article 39). Outside a built-up area that exception does not apply, and the bus is making an ordinary manoeuvre.

Why this topic can end the exam on its own

The category-B theory exam has 50 multiple-choice questions, and you pass with 41 points out of 50. A missed question costs 1 point. A missed question about a serious offence, or about the speed limit, costs 5, and two of those mean you do not pass, whatever your other answers score.

Which rules count as serious is not a feeling about how dangerous they sound. It is a list in a named decree, and priority supplies a good number of the questions on it. So you could answer 48 questions correctly and still not pass, if two priority questions went the other way. We explain the scoring in full in our guide to 41 out of 50.

This is not a reason to be anxious. It is a reason to spend time where the loss is largest, and to treat a shaky priority answer in practice as worth five times the attention of a shaky one anywhere else.

How to drill it until it is automatic

1. Learn the order, not the rule. Officer, lights, signs, markings, then right. Say it at every junction you pass as a passenger until it is boring.
2. Learn the four signs by shape. Inverted triangle, octagon, yellow diamond, and the diamond with a black bar through it. Our guide to Belgian road signs by family covers the rest of the family.
3. Practise the question, not the picture. In an exam question, ask “has anything here taken priority away from me?” rather than “do I have priority?”. The second question catches the sign you did not see, the tram you did not expect and the cycle path you forgot to look along.
4. Practise under exam conditions. A rule you can explain in a quiet room is not the same as a rule you can apply in 15 seconds with a picture in front of you.
