Understanding traffic rules is fundamental for the French driving license theory exam. While France generally follows the 'priorité à droite' rule at unmarked junctions, this article explains the critical exception: road signs and signals always override this default. You will learn to identify situations where signs dictate priority, ensuring you navigate intersections and roundabouts correctly and safely, a key aspect tested in the official Code de la route exam.

Article content overview
Understanding the nuances of priority rules is fundamental to successfully passing the French driving license theory exam, known as the Examen Théorique Général (ETG). While France famously adheres to the priorité à droite principle at many unmarked junctions, this fundamental rule can be, and often is, superseded by official road signage and traffic signals. Mastering this hierarchy of rules is crucial for safe driving and for answering exam questions correctly, as confusing these priorities can lead to dangerous situations and exam failures. This article delves into how road signs and signals always override the default right-hand priority rule in France, equipping you with the knowledge to navigate intersections with confidence.
In the absence of any specific traffic control, French law dictates that drivers must generally yield to vehicles approaching from their right. This is the core of the priorité à droite rule, a principle deeply ingrained in the French traffic system. It applies at most unmarked intersections, country roads joining main roads, and even certain residential areas where no signs indicate otherwise. The intention behind this rule is to establish a clear, albeit sometimes challenging, default priority system to manage traffic flow.
However, the simplicity of priorité à droite can be deceptive. Drivers must remain constantly aware of their surroundings, as this rule is frequently modified or entirely cancelled by a variety of traffic signs and signals that are strategically placed to manage flow and safety more effectively. Failing to recognise these signs and adhering blindly to the right-hand rule is a common pitfall for learners and can lead to significant hazards.
The Code de la route clearly establishes that official road signs and traffic signals take precedence over the general priorité à droite rule. This means that if a sign explicitly indicates who has priority or establishes a different rule, that sign's instruction must be followed. This hierarchy is paramount for ensuring predictable traffic behaviour and preventing accidents. It's a critical concept tested thoroughly in the theory exam, often through scenarios that present seemingly conflicting information.
Understanding this hierarchy is not merely about memorising rules; it's about developing a proactive approach to driving. As you approach any junction, your primary responsibility is to look for signs and signals that might alter the default priority. This includes yield signs, stop signs, priority road signs, and traffic lights, all of which provide specific instructions that override the general priorité à droite.
Several types of road signs are specifically designed to manage priority at junctions and can either grant you priority, require you to yield, or explicitly cancel the priorité à droite rule. Familiarising yourself with these signs is a cornerstone of preparing for the French theory test.
These signs inform you that you have the right of way on the road you are currently travelling on.
This "priority road" sign, often seen at the start of a route or after an intersection where priority has been established, means you can proceed without yielding to traffic from the right. However, you must still be aware of other vehicles, especially those who might not respect your priority, and ensure they are indeed yielding.
This sign signals that the priority you held is about to end. Immediately after this sign, the general rules of the road will apply, which could mean returning to priorité à droite or encountering another sign that dictates a different rule. You must be prepared to yield if necessary after passing this sign.
These signs explicitly tell you to yield to other traffic.
The yield sign (often a triangle pointing downwards) is a clear indication that you must give way to traffic on the intersecting road. This includes vehicles already on that road and potentially vehicles approaching from the right if the intersection is unmarked beyond the yield sign.
The stop sign is the most definitive command to stop. You must bring your vehicle to a complete halt and only proceed when it is safe to do so, yielding to all other traffic, including vehicles that might have priority based on other signage or the priorité à droite rule.
Roundabouts (ronds-points or giratoires) are a common feature of French roads, and their priority rules can be a source of confusion. While many modern roundabouts are designed with a "yield on entry" principle (meaning traffic entering the roundabout must yield to traffic already on it), this is not universal and is often clarified by signage.
In France, many roundabouts use the yield sign on entry, effectively meaning traffic on the roundabout has priority. However, older designs or specific configurations might not have these signs, reverting to priorité à droite. It is absolutely essential to observe the signs at each roundabout.
These signs, often accompanied by a circular arrow, dictate the direction of travel around a roundabout. They are crucial for understanding how to navigate the junction safely and correctly.
When approaching a roundabout marked with yield signs on entry, you must yield to vehicles already circulating. Once you have entered, you generally have priority over any new vehicles attempting to enter, until you reach your desired exit.
The theory exam frequently presents scenarios that test your understanding of how signs override priorité à droite. These questions often involve approaching an intersection where a yield sign, stop sign, or priority road sign is present, sometimes alongside other vehicles that might appear to have the right of way according to the default rule.
For instance, you might be approaching an intersection where a vehicle is to your right, but you are on a road marked with a "priority road" sign. In this case, your priority road sign explicitly grants you priority, and the vehicle to your right must yield to you. Conversely, if you are on an unmarked road and see a vehicle approaching from your right on a road marked with a "priority road" sign, that vehicle has priority, and you must yield.
Another common scenario involves traffic lights. When traffic lights are functioning, they always dictate priority, overriding both priorité à droite and any other road signs. A red light means stop, a green light means proceed with caution, and so on, regardless of what other signs might suggest or the position of other vehicles.
The cédez-le-passage sign, often represented by a downward-pointing triangle (similar to the international yield sign), is crucial. When you encounter this sign, it means you must give way to traffic on the road you are entering or crossing. This instruction is direct and overrides any presumption of priority from the right. It is commonly used at the end of priority roads, on merge lanes, and at junctions where traffic on the main road is significantly heavier.
The critical aspect of yielding is not just stopping but being prepared to stop. This means adjusting your speed as you approach the junction, scanning for traffic, and being ready to halt if necessary. Failing to yield when required is a frequent cause of accidents and a common mistake flagged in driving assessments and theory exams.
While not directly related to intersection priority, it's worth noting that France has implemented environmental zones (zones à faibles émissions or ZFE) in many cities. These zones restrict access for vehicles based on their emission levels, often indicated by specific vignettes (stickers) displayed on the vehicle. While these rules govern access to certain areas, they do not alter the fundamental priority rules at intersections within those zones. You still need to apply the priorité à droite or respect the signage as usual.
The interplay between the default priorité à droite rule and the overriding authority of road signs and signals is a cornerstone of French road law and a vital topic for the permis de conduire theory exam. By understanding that signs and signals always take precedence, you can approach any junction with clarity and safety. Always be vigilant, always look for signage, and always be prepared to yield if the situation demands it. Mastering these principles will not only help you pass your ETG but also contribute to becoming a more responsible and safer driver on French roads.
In French traffic law, the default 'priorité à droite' rule—which gives vehicles approaching from the right priority at unmarked junctions—can always be superseded by official road signs and traffic signals. Signs such as the priority road (B1), yield (B2), and stop (B4) establish specific obligations that must be followed over the general right-hand rule. At roundabouts, yield signs on entry typically grant priority to circulating traffic, but signage at each roundabout must always be observed. The key to both safe driving and passing the ETG is to look for signage first at every junction, as this provides the definitive answer on priority.

Road signs and traffic signals always take precedence over the default 'priorité à droite' rule at French junctions.
The priority road sign (B1) grants you right of way and exempts you from yielding to traffic from the right.
Yield signs (B2) and stop signs (B4) must be obeyed regardless of any vehicles approaching from your right.
When approaching any junction, identify signage first—it provides the definitive answer about who has priority.
Traffic lights override all other priority rules and signage when they are functioning.
B1 = priority road (you have right of way), B2 = céder-le-passage (yield), B3 = end of priority road, B4 = stop sign.
Priority hierarchy: traffic lights > road signs > céder-le-passage/yield > priorité à droite.
Many French roundabouts use yield-on-entry, meaning traffic already on the roundabout has priority, but always check for signs.
After a B3 'end of priority road' sign, standard rules apply—often reverting to priorité à droite.
Environmental zones (ZFE) affect vehicle access but do not change intersection priority rules.
Assuming véhicule à droite always has priority without first checking for override signs.
Forgetting that a B1 priority road sign means vehicles to your right must yield to you.
Treating all roundabouts the same—some older designs may not have yield-on-entry signs.
Failing to come to a complete stop at a B4 stop sign, instead just slowing down.
Overlooking yield signs (B2) at the end of priority roads, leading to incorrect right-of-way assumptions.

Find clear and practical answers to common questions learners often have about French Priority Rules: Signs vs 'Priorité à Droite'. This section helps explain difficult points, remove confusion, and reinforce the key driving theory concepts that matter for learners in France.
The 'priorité à droite' (priority to the right) rule dictates that at unmarked junctions or intersections where no other signs or signals are present, drivers must yield to traffic approaching from their right.
Yes, traffic lights (feux tricolores) and other traffic signals, such as police officer signals, always override the 'priorité à droite' rule. You must follow the instructions of the lights or signals.
Priority signs, such as a 'Cédez le passage' (give way) sign or a 'Stop' sign, explicitly change the priority at an intersection. When these signs are present, they cancel the 'priorité à droite' rule, and you must obey the sign's instruction.
Yes, signs like the 'Carrefour à sens giratoire' (roundabout) sign often indicate a specific priority flow. Also, a 'Priorité' (priority road) sign indicates you have priority over traffic from side roads.
If a roundabout is unmarked (which is rare but possible), the 'priorité à droite' rule could theoretically apply, meaning you'd yield to traffic already on the roundabout if they are coming from your right. However, most French roundabouts are regulated by signage ('Cédez le passage' or 'Priorité'). Always check for signs first.
