This lesson introduces the foundational rules of the Code de la route specifically adapted for Category AM licence holders. By exploring the legal framework and operational requirements for cyclomoteurs and light quadricycles, you will gain the knowledge necessary for both the official exam and safe real-world riding in France.
Lesson content overview
Navigating public roads safely in France requires a deep understanding of the official Code de la route (French Traffic Regulations). For Category AM licence holders—who typically operate lightweight two-wheeled mopeds, scooters, or light quadricycles—this knowledge is not just a requirement to pass the theoretical exam; it is a vital shield against the inherent vulnerability of operating smaller, slower vehicles in dense traffic.
This lesson details the specific traffic laws, speed limits, vehicle standards, and road access restrictions that govern Category AM operators under French law. By mastering these concepts, you will ensure legal compliance, avoid costly penalties, and protect yourself and other road users.
Before exploring the rules of the road, you must understand the exact legal classification of the vehicles you are permitted to operate. In France, the Category AM licence (formerly known as the Brevet de Sécurité Routière or BSR) applies to light motorized vehicles. These are divided into two primary classifications:
A two- or three-wheeled motorized vehicle with a maximum design speed of 45 km/h, an engine cylinder capacity not exceeding 50 cm³ (for internal combustion engines), or a maximum continuous rated power of no more than 4 kW (for electric motors).
A four-wheeled light vehicle with a maximum design speed of 45 km/h, an empty mass of under 425 kg, and an engine capacity or continuous rated power restricted similarly to a moped (≤ 50 cm³ for petrol engines or ≤ 4 kW for other engine types).
The strict physical limits of these vehicles explain why they are subject to unique operating rules. Because they cannot match the speed or mass of standard passenger cars, the Code de la route establishes protective frameworks to keep them separated from high-speed traffic flows while integrating them safely into urban and suburban environments.
In France, speed limits are strictly enforced to minimize kinetic energy in collisions and to manage traffic flow. As an AM licence holder, you must adhere to a dual layer of speed restrictions: the absolute design limit of your vehicle and the variable speed limits of the road you are traversing.
No matter what speed limit is posted on a road, a Category AM vehicle must never exceed 45 km/h. This is a mechanical and legal ceiling. Even if you are riding on an open, suburban road with a general limit of 80 km/h, you must remain at or below 45 km/h.
Modifying a vehicle’s engine or transmission to exceed this limit (known as débridage or tampering) is a serious criminal offense in France, leading to heavy fines, vehicle confiscation, and a voided insurance policy.
While 45 km/h is your maximum allowed speed, you must frequently adapt your velocity downward based on local signs, weather conditions, and road classifications.
The "Limitation de Vitesse" sign for light vehicles: Some signs may explicitly mention a lower limit for two-wheelers, such as "30 km/h pour les 2-roues à moteur" or include a specific moped pictogram. You are legally required to obey these targeted restrictions.
Because Category AM vehicles have a maximum speed of 45 km/h, they are legally barred from high-speed roadways. Entering a restricted road on a moped is highly dangerous and carries severe penalties.
AM vehicles are strictly prohibited on:
These roads feature traffic moving at 110 km/h to 130 km/h. The extreme speed differential between a 45 km/h moped and a 130 km/h car creates a severe collision risk.
AM riders must generally stick to secondary roads, urban streets, and departmental routes (routes départementales).
Right-of-way rules in France are strictly codified. As an AM rider, you must respect standard priority protocols while remaining acutely aware of your vulnerability.
This is the default priority rule in France. At any intersection where no traffic lights, stop signs, yield signs, or road markings are present, you must yield to vehicles approaching from your right.
Conversely, traffic coming from your left must yield to you, but you should never force your priority. Many drivers fail to see small AM vehicles.
When entering a roundabout in France, you must yield to traffic already circulating inside the ring (indicated by the yield sign and triangles painted on the road surface at the entrance).
Road markings on French asphalt convey critical legal boundaries that dictate your path and overtaking limits.
Verify the road markings: Ensure there is no solid white line (ligne continue) preventing you from crossing into the adjacent lane, unless local laws explicitly permit straddling a solid line to pass a very slow cyclist under safe conditions.
Check your surroundings: Check your left-hand mirror and perform a direct shoulder check (blind spot check) to ensure no vehicle is already overtaking you.
Signal your intent: Activate your left turn indicator to warn traffic behind you.
Maintain a safe lateral distance: Under French law, you must maintain a minimum lateral clearance of 1.0 metre in urban areas and 1.5 metres on open country roads (outside urban areas) when passing a cyclist or pedestrian.
Complete the pass: Accelerate smoothly up to your legal limit, return to the right lane when you can see the cyclist in your mirror, and turn off your indicator.
Under the French Code de la route, certain vehicle components are legally required to maintain roadworthiness. Operating a vehicle missing this equipment can result in immediate fines and vehicle impoundment.
Small vehicles have a low visual profile, making proper lighting critical for safety.
You must have structural awareness of the traffic behind you.
Every AM vehicle must be equipped with a functional horn (avertisseur sonore) that is audible from at least 150 metres away. The law restricts its use inside urban areas to cases of immediate, pressing danger. Continuous or aggressive honking to express frustration is illegal.
Your vehicle's exhaust system must feature a legally approved, undamaged silencer (pot d'échappement aux normes). Modifying the exhaust to increase engine noise is a violation of environmental and traffic laws.
The Code de la route places strict legal requirements on personal protective equipment (PPE) and how you transport passengers.
Both the rider and any authorized passenger must wear an approved, certified motorcycle helmet. The helmet must feature a label proving compliance with French/European standards:
Failure to wear an approved, buckled helmet results in a heavy fine and, if the operator holds a full driving licence with points, the loss of demerit points.
You cannot automatically carry a passenger on a moped. Strict legal conditions must be met:
Understanding the legal consequences of non-compliance helps reinforce the rules. The table below outlines frequent errors made by Category AM operators and their real-world consequences under French traffic law.
| Violation | Immediate Risk / Hazard | Legal Consequence in France |
|---|---|---|
| Exceeding 45 km/h via engine modification | Structural instability, brake failure, severe crash impact | Vehicle confiscation, heavy criminal fine, insurance voided |
| Riding on an Autoroute or Expressway | Being struck from behind by high-speed vehicles | Heavy class 4 fine, immediate vehicle towing |
| Riding without a certified helmet | Fatal head trauma in even a minor fall | Class 4 fine, immobilization of the moped |
| Riding with a non-functional rear red light at night | Complete rear-end collision risk | Fine, vehicle prohibited from moving until fixed |
| Carrying a passenger on a single-seat moped | Unbalanced vehicle, loss of steering control | Class 4 fine |
| Crossing a solid white line | Head-on collision with oncoming vehicles | Fine, loss of demerit points (if holding a point-based licence) |
These real-world scenarios illustrate how to combine these rules during everyday riding.
You are riding your scooter home at 18:00 on a cloudy day. You enter a residential neighborhood marked with a "Zone 30" sign.
You are riding on a wide rural road (departmental route) with a general limit of 80 km/h. A tractor is crawling ahead of you at 15 km/h. The road is marked with a solid white line (ligne continue).
