Reference Decision: cc • No. 63-91.103 • 1963-11-06 • View the decision →
Imagine: you are driving calmly through the streets of Chamalières, when suddenly, at an intersection you use every day, a brand new Stop sign appears. You stop, of course, but you wonder: does the mayor really have the right to decide alone where to place these signs? And if you don't stop, what is the penalty?
This is precisely the question the Court of Cassation decided in 1963, in a case from Strasbourg. A motorist challenged a ticket for failing to obey a Stop sign, arguing that the municipal order which installed it was illegal. The high court ruled in favour of the mayor: yes, the mayor may regulate traffic within his municipality, including by requiring stops at intersections, and a user who does not stop commits an offence.
This decision, though old, remains a cornerstone of traffic law. It reminds drivers that the mayor's police power is broad, and reminds adjoining landowners that signage can change without their consent. Let us break it down together.
The Facts: A Story Like Many Others
In Strasbourg in the 1960s, the municipality issued an order to regulate traffic at several intersections by placing Stop signs there. A driver, whom we will call Mr X, was ticketed for failing to stop at one of these intersections. Contesting the fine, he took the case to court.
His main argument: the mayor's order was irregular. According to him, the mayor did not have the power to impose a Stop without a resolution of the municipal council or prefectoral authorisation. He argued that signage must comply with strict national regulations and that local initiative was contrary to the Highway Code.
The municipality of Strasbourg, for its part, argued that Article R.27 of the Highway Code (now codified in Article R.411-25) gave the mayor the power to regulate traffic within the municipality, including by installing Stop signs. The case was heard at first instance, then on appeal, before reaching the Court of Cassation.
Twist: the Court of Cassation upheld the driver's conviction. It held that the municipal order was regular, as it was made in accordance with Article R.27, and that the motorist had indeed committed an offence by not stopping. This decision ended the challenge, but above all established a clear principle: the mayor may, on his own authority, impose Stops in his commune.
The Court's Reasoning — Analysed
The Court of Cassation, in its judgment of 6 November 1963 (No. 63-91.103), relied on Article R.27 of the Highway Code. This article, in the version then in force, authorised the mayor to regulate traffic within the municipality, particularly at intersections. The Court considered that this provision gave the mayor sufficient power to impose Stop signs without further formality.
The reasoning is simple: the mayor is the traffic police authority in his commune. He may therefore, by order, decide on signage, provided it complies with safety rules. In this case, the municipal order of Strasbourg explicitly provided that drivers must come to a stop at the indicated intersections. The driver, by not stopping, violated this obligation.
The Court rejected the driver's argument that the order was illegal. It specified that the publication of a protocol constituting an international undertaking (mentioned in the text of the decision) had no impact on the validity of the municipal order. In other words, even if the commune had signed an agreement with the State, this did not limit the mayor's power over local signage.
This decision is a confirmation of earlier case law: the mayor's police power is broad and discretionary. It has not been overturned since, and courts continue to apply it. The judges simply reminded that the road user must obey signage, even if he challenges the legality of the order. The challenge must be made through legal proceedings, not by ignoring the sign.
What This Means for You — Practically
For motorists: if you see a Stop sign, you must stop, whether you agree with its location or not. The offence is committed as soon as you fail to come to a complete stop. In Issoire, for example, a driver who runs a newly installed Stop sign on Rue de la République could be ticketed, even if he challenges the order. The fixed penalty fine is €135 (reduced to €90 if paid promptly), and a deduction of 4 points from the driving licence is provided.
For adjoining landowners: you cannot prevent the mayor from installing a Stop sign in front of your property. If you believe the signage is abusive, you must challenge the order before the administrative court within two months of its publication. In the meantime, you must obey the sign.
For local authorities: this decision confirms that the mayor may act alone, without a resolution of the municipal council. This simplifies traffic management. However, he must justify his order on safety grounds and not act arbitrarily. In Chamalières, an order could be annulled if it is made for reasons unrelated to traffic (for example, to harm a shopkeeper).
Four Tips to Avoid This Type of Dispute
- Always obey the signage in place. Even if you think it is illegal, do not defy it. You risk a fine and points deduction. File a challenge in parallel.
- If you want to challenge a municipal order, act quickly. The deadline for appeal is two months from the publication or posting of the order. After that, it becomes final.
- Check the reasoning behind the order. A good lawyer will analyse whether the mayor's decision is justified by safety considerations (visibility, accident history, traffic flow).
- If you own a corner plot, plan ahead. The mayor may install a Stop sign there, which could affect the value of your property. Inquire at the town hall before buying.

This decision is part of a consistent line. As early as 1956, the Council of State recognised the mayor's power in signage matters (CE, 14 December 1956, Ville de Nice). More recently, the Court of Cassation clarified that the mayor may even impose one-way streets or speed limits without prefectoral authorisation (Cass. crim., 18 March 2008, No. 07-86.781).
The trend is therefore towards strengthening municipal power. However, the courts check that the order is not disproportionate. For example, a Stop sign placed at an intersection with poor visibility is justified; but if it is placed for a purely commercial purpose, it could be annulled. In future, expect mayors to use this prerogative more and more to calm traffic, especially in residential areas.
Frequently Asked Questions
Can I challenge a Stop sign if I think it is badly placed?
Yes, but you must do so by filing an application to annul the municipal order before the administrative court, not by refusing to stop. The deadline is two months.
What is the penalty for failing to stop at a Stop sign?
A fixed penalty fine of €135 (reduced to €90) and a deduction of 4 points from the driving licence. In the event of an accident, the criminal and civil consequences can be severe.
Can the mayor install a Stop sign without the agreement of the municipal council?
Yes, this is an individual decision falling within his police power. No resolution is necessary, unless the order provides for exceptional expenditure.
Can a private individual request the installation of a Stop sign?
Yes, by sending a reasoned request to the town hall. The mayor is not obliged to accept it, but he must examine the request and justify any refusal.
Must the municipal order be published to be enforceable?
Yes, it must be posted at the town hall and often published in a municipal bulletin. The signs must comply with regulations (NF standard).
