This lesson provides an essential guide to the specific traffic signs and markings encountered by professional drivers of categories D1, D, D1E, and DE. By mastering these regulatory symbols, you will ensure full compliance with the Code de la route, avoid hazardous physical collisions, and maintain professional safety standards across the French road network.
Lesson content overview
Navigating heavy passenger vehicles, such as buses, coaches, and articulated public transport units, demands a sophisticated understanding of the French Code de la route (highway code). Because of their substantial dimensions, high weight profiles, and the responsibility of carrying dozens of passengers, Category D, D1, D1E, and DE drivers must adhere to regulatory road signs designed specifically for heavy passenger vehicles.
Failing to recognize these indicators can lead to severe structural accidents, such as striking low bridges, compromising the integrity of historical routes, obstructing municipal services, or incurring substantial financial penalties and license points. This lesson details the specific road signs, markings, and priority signals that govern passenger transport operations across France.
Buses and coaches present unique spatial profiles. Double-decker coaches (autocars à deux étages) and modern urban buses equipped with roof-mounted climate control units, auxiliary heaters, or cellular receivers have heights that far exceed standard passenger cars.

The primary indicator for vertical clearance is the Sign B11, a regulatory prohibition sign consisting of a red circle with black arrows pointing to the top and bottom of a central numerical value (expressed in metres).
Under Article R412-43 of the Code de la route, any driver who attempts to pass a Sign B11 with a vehicle exceeding the designated height is subject to a class 4 fine, potential vehicle impoundment, and civil liability for any structural damage caused.
Know Your Exact Fleet Height: Memorize or display the exact total height of your bus, including all auxiliary roof gear, on a placard in the driver's cockpit.
Scan Advanced Warning Signs: Look for rectangular advisory signs (panneaux de présignalisation) placed several hundred metres before bridges, tunnels, or underpasses, which provide early detour opportunities.
Take the Mandatory Detour: If your vehicle's physical height matches or exceeds the posted limit, execute the signed detour route immediately. Do not enter the restricted approach.
Buses and heavy coaches exert significant stress on road surfaces, historic bridges, and elevated urban causeways. Consequently, the French road network utilizes weight-restriction signs to preserve public infrastructure.
In France, heavy vehicle weight signs typically refer to the PTAC (Poids Total Autorisé en Charge, or Gross Vehicle Weight). The PTAC is a fixed, certified value printed on the vehicle registration document (Carte Grise). Even if a coach is currently empty of passengers, if its registered PTAC exceeds the value displayed on Sign B12, it is legally prohibited from traversing that route.
The maximum legal weight of the individual vehicle when fully loaded with fuel, driver, passengers, and luggage, as certified by the manufacturer and transport authorities.
Some older bridges, rural routes, or historic city centres are limited by axle load rather than total vehicle weight. This is indicated by Sign B13.
[Front Axle] [Rear Tandem Axles]
O===========O O===========O===========O
Max: 4.5t Max: 7.5t per axle
For D-category vehicles, loading must be balanced. An uneven distribution of heavy passenger luggage in under-floor bays, or an overload of standing passengers at the rear of an urban bus, can cause a single axle to exceed legal limits even if the total vehicle weight remains below the maximum PTAC.
To improve the punctuality of public transport and reduce municipal gridlock, French road networks utilize dedicated bus lanes (Voies réservées aux transports en commun).
Reserved lanes are designated using both vertical signs and explicit horizontal road surface markings.
Designated stops are critical for passenger safety, wheelchair ramp deployment, and maintaining predictable traffic patterns.
The physical space of a bus stop is delimited by yellow zig-zag pavement markings (marquage en zig-zag jaune).

Stopping outside of designated, regulated bus stops to load or unload passengers is a serious infraction under the Code de la route. Unregulated stops put boarding passengers at risk of being struck by overtaking vehicles or cyclists.
Speed limits for Category D vehicles in France are not always the same as those for light passenger cars. Speed restrictions are based on the vehicle's total weight classification and the type of route.
Under Article R413-8 of the Code de la route, passenger transport vehicles with a GVW (PTAC) exceeding 3.5 tonnes must adhere to the following strict speed limits:
| Road Type | Standard Buses & Coaches (PTAC > 3.5t) | Articulated / Towing Vehicles (PTAC > 12t or with Trailer) |
|---|---|---|
| Motorways (Autoroutes) | 90 km/h (100 km/h if equipped with ABS and specific safety approvals) | 90 km/h |
| Dual Carriageways (Routes à deux chaussées séparées) | 90 km/h | 80 km/h |
| Standard Rural Roads (Routes hors agglomération) | 80 km/h | 80 km/h |
| Urban Built-Up Areas (Agglomérations) | 50 km/h | 50 km/h |
All passenger transport vehicles over 3.5 tonnes must display round speed limit stickers on the rear left of the vehicle body. These discs indicate the maximum speeds the vehicle is legally allowed to travel (e.g., "70", "80", "90", or "100" discs depending on the vehicle classification and whether it is configured for urban or interurban transit).
In many French metropolitan areas, public transport networks use dedicated traffic light signals at intersections to maintain scheduled services.
Where buses run on physically separated lanes (sites propres), standard three-color traffic lights are replaced by white-light geometric indicators on a black background.
[ | ] Vertical Bar --> Go (Equivalent to Green Light)
[ o ] White Circle --> Prepare to Stop (Equivalent to Amber Light)
[ - ] Horizontal Bar --> Stop (Equivalent to Red Light)
These signals are highly directional and apply strictly to the vehicle operating within the dedicated transit corridor. General traffic must ignore these white-light signals and follow standard traffic lights.
During heavy rain, snowfall, or dense fog, overhead warning structures and vertical signs can become obscured.
A common mistake for new Category D drivers is assuming that passenger placement does not affect weight limits.
To ensure safe passenger transport and pass the Category D theory exam, you must memorize the direct legal consequences of each specific road sign:

Yes, while the symbol is the same, the legal implications are more severe. A bus or coach driver must always verify their vehicle's actual height, including roof equipment, against the sign, as failure to do so can lead to catastrophic structural damage and significant liability.
Look for road markings featuring a diamond symbol or the word BUS painted on the tarmac, accompanied by vertical signs indicating access rules. These zones are strictly monitored, and improper use can result in fines that impact your professional record.
No, specific signs or supplementary plates may impose lower speed limits based on vehicle type or size. As a professional driver, you must prioritize these vehicle-specific restrictions over the general speed limits indicated for cars.
If you are driving a fully loaded bus or coach, you must always adhere to the posted weight limit signs. You should have a pre-planned route that avoids these restricted zones, and if you encounter one unexpectedly, you must safely find an alternative route immediately to maintain compliance.
