Defining Digital Advertising Under French Law
The Code de l'environnement does not itself define digital advertising (publicité numérique). The definition comes from the ministerial technical notice annexed to the instruction of 25 March 2014, which describes it as a particular form of illuminated advertising that relies on the use of a screen. This definitional approach is significant in two respects: it confirms that digital advertising is a subcategory of illuminated advertising (and therefore subject to all illuminated advertising rules as a baseline), and it locates the distinguishing feature in the technology — the screen — rather than in the content or animation technique.
The notice identifies three types of digital advertising screen, which the legal framework treats differently in certain contexts:
Displays featuring moving or evolving visual content: the appearance of a slogan, a price, an evolving form, a trembling pictogram, and similar dynamic graphics. The defining characteristic is movement or change within the displayed content.
Most commercially common format for roadside digital billboardsDisplays showing a succession of still images — also called déroulant numérique. Each image is static; the screen cycles through a playlist of static advertisements. No animation occurs within any single displayed image.
The only digital type exempt from extinction on transport furniture during service hoursFull-motion video content played on an outdoor screen. The most visually intensive format, combining motion and the full range of video production techniques.
Subject to all the same technical constraints as animated advertisingThe distinction between animated images and fixed-image scrolling matters practically for the night-time extinction rules: the exemption for digital advertising on transport street furniture during service hours applies only to fixed-image digital displays, not to animated content or video. A bus shelter screen cycling through static posters during night transport service hours can remain on; the same screen showing animated content cannot.
Digital Advertising's Position in the French Legal Framework
Because digital advertising is a subcategory of illuminated advertising, it inherits the full illuminated advertising regime as its baseline — including the complete ban in small agglomerations (under 10,000 inhabitants not forming part of an urban unit over 100,000), the prior authorisation requirement from the mayor, the mandatory night-time extinction between 1am and 6am, the energy minister's emergency curtailment power, and the brightness and energy efficiency norms. Article R 581-41 of the Code de l'environnement then adds screen-specific requirements on top of that baseline.
Article R 581-41 itself specifies that not all of its provisions are yet in force — some requirements await publication of implementing ministerial orders that had not yet appeared at the date of the source text. Operators and practitioners should monitor the regulatory gazette for these orders, which will complete the framework.
Surface Area and Height Limits
The standard size limits for digital advertising under Article R 581-41, I are the same as those for non-digital illuminated advertising: 8 m² maximum surface area and 6 metres maximum height above ground (Art. R 581-41, I-al. 1, as amended by Decree 2023-1409 of 29 December 2023). The format of the display (screen vs. lit panel) does not, in itself, justify different dimensional treatment in standard locations. Exceptions apply at high-volume airports and large sports venues.
Surface Area Calculation
The surface area of a digital advertising device is measured using the same method as for other advertising: the entire device whose principal function is to carry the advertising — the whole screen and its housing, not just the viewable display area. Structural support elements (masts, poles, brackets) whose principal function is to hold the device are not included (CAA Nancy, 18 May 2017, n° 16NC00986), now codified in Article R 581-24-1.
The High-Volume Airport Exception
At airports with annual passenger flows exceeding three million, digital screens may reach 50 m² and 10 metres in height. The regulation expressly confirms that brightness and extinction rules continue to apply in full at these airports — the enlarged dimensional allowance carries no relaxation of energy or night-time obligations. The qualifying airports are: Paris-Charles-de-Gaulle, Paris-Orly, Nice-Côte-d'Azur, Marseille-Provence, Lyon-Saint-Exupéry, Bâle-Mulhouse, Toulouse-Blagnac, Bordeaux-Mérignac, Nantes-Atlantique, and Paris-Beauvais.
Sports Venues: The Height Derogation for Digital Screens
At sports facilities with at least 15,000 seats, digital advertising may reach 50 m² and 10 metres, inside or outside agglomerations. Beyond 10 metres, a further height derogation is available specifically for digital advertising installed on a wall, façade, or fence at the venue — granted by the mayor (outside agglomerations) or the municipal/intercommunal council (inside agglomerations), applying the same assessment criteria as the equivalent non-luminous derogation.
The Ambient-Light Gradation Requirement
One of the most technically specific obligations for digital advertising is the mandatory ambient-light gradation system. Article R 581-41, III requires that digital advertising devices located inside agglomerations — and outside agglomerations on the grounds of airports and railway or road stations — be equipped with a system that automatically adapts the screen's luminance output to the ambient light level at the device's location.
Daytime — Full Ambient Light
The screen operates at or near its full designed luminance to remain legible against daylight. The gradation system allows maximum output when ambient light is high.
Dusk / Transitional Light
As ambient light falls, the gradation system automatically reduces luminance proportionally. The screen remains visible but does not retain daytime brightness as the environment darkens.
Night — Low Ambient Light
Screen brightness is reduced to its nighttime level, avoiding dazzle for drivers, pedestrians, and residents. The device must then switch off entirely between 1am and 6am, unless an exemption applies.
The purpose of the gradation requirement is to prevent dazzle (éblouissement) — the regulatory term used. The system must operate automatically and continuously, without manual adjustment. Programming a scheduled brightness reduction at a fixed evening hour does not satisfy this requirement — the system must respond dynamically to actual ambient light conditions in real time.
The ambient-light gradation obligation applies to digital screens in two categories of location: (1) inside all agglomerations — regardless of population size; and (2) outside agglomerations, on the grounds of airports and railway or road stations. It does not apply to digital screens at sports venues outside agglomerations — those remain subject to the general brightness norms but are not expressly covered by the gradation requirement under Article R 581-41, III.
Prohibited Zones for Digital Advertising
Digital advertising inherits the full range of illuminated advertising location prohibitions — including the complete ban in small agglomerations under 10,000 inhabitants not part of a large urban unit, and the absolute prohibitions under Article L 581-4. Digital advertising on urban street furniture is then subject to a further set of additional prohibited zones under Article R 581-42, cross-referencing Article L 581-8.
- Agglomerations of fewer than 10,000 inhabitants — more restrictive than the general illuminated advertising ban, which excludes only those small agglomerations not forming part of a large urban unit; digital advertising on street furniture is banned in all agglomerations under 10,000 inhabitants without qualification
- Natural regional parks (parcs naturels régionaux)
- National park membership areas (aires d'adhésion des parcs nationaux)
- Natura 2000 zones — zones spéciales de conservation (ZSC) and zones de protection spéciales (ZPS) under Article L 414-1 of the Code de l'environnement
The prohibited zones for digital advertising on street furniture are governed by a different and more restrictive provision than the general digital advertising rules. In particular, the ban on street furniture digital advertising in agglomerations under 10,000 inhabitants applies without the urban unit qualification that limits the general illuminated advertising ban. A small town that falls within a large urban unit can in principle have non-street-furniture illuminated advertising — but its street furniture cannot carry digital advertising of any kind.
Digital Advertising on Urban Street Furniture
Urban street furniture (mobilier urbain) installed on the public domain may, in agglomerations, carry advertising as an accessory function alongside its primary civic purpose. When that advertising takes the form of a digital screen, the full digital advertising regime applies to the furniture, with specific adaptations in Article R 581-42.
No Density Limit for Street Furniture
Street furniture advertising is exempt from the general density rules limiting the number of devices per plot frontage. The density calculation under Article R 581-25 concerns devices on land plots, not equipment on the public domain governed by separate concession arrangements.
The Residential Window Setback for Digital Street Furniture
Digital advertising on urban street furniture must not be placed within 10 metres of a window (baie) of a residential building on an adjacent plot, where the digital advertising would be visible from that window and situated parallel to it (Art. R 581-42, al. 4). The measurement is specific: from the bottom of the window to the top of the digital screen. This diagonal measurement method may produce a larger or smaller effective separation than a simple horizontal distance, depending on the relative heights of the window and the screen.
Luminance, Extinction, and Gradation for Digital Street Furniture
Digital advertising on urban street furniture is subject to all the technical requirements applicable to digital advertising generally: brightness and energy efficiency norms, mandatory night-time extinction between 1am and 6am (with the transport furniture exemption for fixed-image content during service hours), and the ambient-light gradation system requirement.
RLP Treatment of Street Furniture Digital Advertising
A Local Advertising Plan does not create an unlawful discrimination by authorising digital advertising principally on street furniture in certain zones while restricting it more on other supports in the same zones. The Nancy administrative court of appeal confirmed that the fact that street furniture carries digital advertising only as a secondary purpose — its primary purpose being civic — provides a legitimate justification for differential treatment in an RLP (CAA Nancy, 19 October 2021, n° 19NC02575).
Specific Rules for Individual Street Furniture Types
Articles R 581-43 to R 581-47 set out size limits and restrictions for specific categories of street furniture. These apply to advertising on those structures whether digital or non-digital:
- Public shelters (abris destinés au public) — maximum 2 m² per individual panel; total advertising surface may not exceed 2 m² plus 2 m² for each full 4.50 m² of covered floor area. No advertising on the shelter roof (Art. R 581-43)
- News kiosks and commercial kiosks on the public domain — maximum 2 m² per individual panel; total advertising surface may not exceed 6 m². No advertising on the kiosk roof (Art. R 581-44)
- Poster columns (colonnes porte-affiches) — may only carry announcements for performances and cultural events; commercial advertising is prohibited (Art. R 581-45)
- Poster masts (mâts porte-affiches) — maximum two back-to-back panels, maximum 2 m² each, usable only for economic, social, cultural, or sporting event announcements (Art. R 581-46)
- Furniture for non-advertising public information or artworks — may not carry commercial advertising exceeding the total surface reserved for those public information displays or artworks (Art. R 581-47)
The RLP's Power to Restrict Digital Advertising Further
The Local Advertising Plan can only tighten the national digital advertising rules — it cannot relax them. In the digital advertising context, specific areas where an RLP may go further than the national baseline include:
- Prohibiting digital advertising in additional zones — an RLP can designate specific streets or areas as digital-advertising-free even where no national prohibition applies
- Imposing stricter extinction hours — an RLP can extend the mandatory extinction window beyond 1am–6am nationally
- Imposing stricter surface area or height limits — an RLP can reduce the 8 m² ceiling or 6-metre height limit in all or part of the agglomération
- Imposing stricter brightness rules — particularly relevant in municipalities concerned about light pollution; the RLP can set lower luminance thresholds than the national norms
- Regulating interior digital displays visible from the public road — an RLP can bring digital screens inside commercial premises within the regulatory framework, imposing extinction hours, surface limits, and energy consumption rules on shopfront screens that would otherwise be entirely outside the advertising regime (Art. L 581-14-4)
One of the most commercially significant RLP powers in the digital context is the ability to bring illuminated and digital advertising inside commercial premises within the advertising framework where those displays are visible from the public road. A municipality with an RLP can impose extinction hours, surface limits, and energy requirements on digital screens in shopfronts that would otherwise be entirely outside the Code de l'environnement's advertising provisions. Businesses with digital displays in their shopfronts must check whether the applicable RLP contains such provisions.
