This lesson focuses on interpreting complex crossroads and schematic priority signs (panonceaux schématiques) found on French roads. By mastering these specialized indicators, you will be able to determine right-of-way accurately, even at unconventional or non-standard intersections. This knowledge is essential for both your ETG theory exam success and safe, confident driving in France.

Lesson content overview
Navigating standard intersections in France requires a solid grasp of basic right-of-way rules, but complex layouts often demand more sophisticated road communication. On French roads, you will frequently encounter intersections where the priority road does not simply continue in a straight line. Instead, it curves, splits, or bends across the crossroad.
To prevent confusion and eliminate ambiguity, the French traffic system uses auxiliary signs known as schematic signs (panonceaux schématiques). These signs provide a clear, top-down visual map of the intersection’s priority layout. This lesson will teach you how to interpret these signs, maintain priority when the main road curves, and handle non-standard intersection layouts safely. This knowledge is crucial for passing the French Category B driving theory exam (Examen de l'Éthique Générale or ETG) and driving confidently on French roads.
A priority road (route à caractère prioritaire) is a designated roadway where drivers have the right of way at all upcoming intersections. This status is established to maintain continuous traffic flow on main thoroughfares, reducing unnecessary stops and minimizing rear-end collisions.
To identify a priority road, look for the yellow diamond-shaped sign. Under the French Code de la route, this is designated as the AB6 sign.
When you are driving on a road marked with the AB6 sign:
Conversely, a secondary road (chemin secondaire) is any road that must yield to the priority road. Drivers on secondary roads will face yield signs (Cédez le passage), stop signs, or road markings indicating they must give way to the main flow of traffic.
Standard road markings and signs can fail to convey priority when an intersection has a non-standard geometry. For instance, if the main road bends 90 degrees to the left and a narrow local street continues straight, who has priority? To resolve this, the French road authority installs a schematic sign (panonceau schématique, categorized under the M9f series) directly beneath the priority road sign or the yield sign.
A schematic sign provides a simplified, overhead diagram of the upcoming intersection. It uses line thickness to dictate right-of-way:
An auxiliary schematic sign placed beneath a main priority or warning sign that depicts a top-down layout of an intersection. The thick line represents the priority road, while the thin lines indicate secondary roads.
By matching the bottom line of the schematic to your current lane, you can instantly determine whether you are on the priority road or a secondary road, and which turning paths maintain that priority.
The core rule of navigating a curved priority layout is the continuity of priority. This principle dictates that the priority road retains its right-of-way status even when it bends, curves, or changes direction within the intersection.
Many novice drivers mistakenly assume that "straight ahead" always has priority. This assumption is a dangerous misconception. If the thick line on the schematic curves to the left, a driver turning left is actually continuing on the priority road and has right-of-way over a driver on a secondary road who is going straight.
To determine priority at a schematic intersection, follow this logical step-by-step process:
Identify your current road status: Look at the bottom branch of the schematic. If it is a thick line, you are currently on the priority road. If it is a thin line, you are on a secondary road.
Locate other vehicles: Determine which branch of the schematic the other vehicles are approaching from. Are they on the thick line (priority) or a thin line (secondary)?
Apply the priority hierarchy: Vehicles on the thick line always have priority over vehicles on the thin lines.
Apply default rules if status is equal: If two vehicles are on the priority road (thick line) or both are on secondary roads (thin lines), resolve their conflict using standard rules, such as yielding to oncoming traffic when turning left or applying the priority-to-the-right rule among themselves.
Let's break down these relationships further:
French traffic law defines clear mandates for priority roads, auxiliary signs, and the termination of priority. Understanding the legal basis of these rules helps prevent costly traffic fines and ensures compliance.
Under Article R411-1 of the Code de la route, the yellow diamond sign (AB6) designates a priority road. This priority remains in effect at all subsequent intersections along that route until it is explicitly terminated by an end-of-priority sign or overridden by higher-priority traffic signals.
Article R413-1 dictates that when an auxiliary schematic sign is present, it must be consulted to determine the exact geometry of the priority and secondary roads. The schematic sign takes precedence over a driver's subjective assumptions about the straightness or size of the roads.
A priority road does not last indefinitely. When the priority status is terminated, you will encounter the AB7 sign.
Once you pass the AB7 sign, the road reverts to default priority rules at the very next intersection. In France, the default rule is priority to the right (priorité à droite), meaning you must stop and yield to any vehicle entering from an intersecting street on your right, unless other signs indicate otherwise.
Normally, solid or dashed lines on the asphalt indicate lane boundaries and stopping points. However, if there is a discrepancy between road markings and a physical schematic sign, the schematic sign takes legal precedence. This ensures that even if old road markings are worn or misleading, the vertical signage clearly dictates the right-of-way.
Even if you are driving on a priority road (thick line) and have right-of-way over all other vehicles, pedestrian safety supersedes vehicular priority. Under Article R415-1, you must yield to any pedestrian who has stepped onto, or clearly intends to step onto, a designated crosswalk (passage piéton).
Navigating crossroads with specific signage is a common area of failure on both the theoretical ETG exam and the practical driving test. Let's analyze the most common mistakes and how to avoid them.
Always remember the French road signage hierarchy:
A driver's ability to safely navigate crossroads with specific signage depends heavily on environmental variables and visibility.
In heavy rain, snow, or thick fog, schematic signs can become difficult to read from a distance. Because the distinction between a thick line and a thin line is subtle, poor visibility increases the risk of misinterpretation.
In urban areas, priority roads often intersect with dedicated bicycle lanes or tramway lines.
To help you study for your French theory exam, use this quick-reference summary of the rules governing crossroads with specific signage:
| Sign / Element | Legal Meaning | Action Required |
|---|---|---|
| Yellow Diamond (AB6) | Priority Road (Route prioritaire) | Maintain speed, proceed with caution, you have right-of-way over cross streets. |
| Thick Line on Schematic | Path of the Priority Road | Follow this line to maintain priority. Signal if you physically turn. |
| Thin Line on Schematic | Secondary Road | Yield to any vehicle on the thick line. |
| Crossed Yellow Diamond (AB7) | End of Priority Road | Revert to default rules (priorité à droite) at the next intersection. |
| Active Traffic Light | Overrides Priority Signs | Ignore the priority signs and obey the light colors. |
| Pedestrians on Crosswalks | Absolute Priority | Always stop for pedestrians, even if you are on the priority road. |
By mastering the visual language of schematic signs and understanding the legal hierarchy of the Code de la route, you will be fully prepared to handle even the most complex intersections safely and pass your driving theory exam with ease.
