Gross Train Weight, known in France as PTRA (Poids Total Roulant Autorisé), is a critical safety threshold defined on a towing vehicle's registration certificate. It dictates the absolute legal limit for the combined weight of both your car and any trailer, including loads, passengers, and fluids. Mastering the rules surrounding PTRA is vital for passing the French driving theory exam (ETG) and determining whether you need a specific trailer license like the B96 or BE.
PTRA
The maximum legally authorized total weight of a towing vehicle combined with its trailer, including all passengers, cargo, and equipment.
Think of PTRA as the 'All-Together' weight limit—it controls the entire Train of vehicles.
Quickly understand the most important facts, rules, and meanings related to Gross Train Weight (PTRA) in French driving theory for France. This focused summary helps learners revise key terminology, traffic concepts, and exam-relevant knowledge efficiently.
See how Gross Train Weight (PTRA) appears in realistic driving situations relevant to France. These examples explain correct behaviour, safety implications, and how Gross Train Weight (PTRA) connects to French driving theory exam questions.
A driver is towing a caravan on a French national road. The car's empty weight is 1,500 kg, its cargo/passengers weigh 400 kg, and the loaded caravan weighs 1,200 kg. The car's registered PTRA (F.3) is 2,800 kg.
Calculate the total weight of the setup (1,500 + 400 + 1,200 = 3,100 kg) and realize it exceeds the 2,800 kg PTRA, meaning the driver must reduce the cargo weight before driving.
Driving with a combined actual weight that exceeds the vehicle's PTRA is illegal and unsafe, as the car's braking system and chassis are not designed to handle a total train weight above its registered limit.
A learner is reviewing a question on the ETG exam asking which category on the 'carte grise' represents the maximum combined weight of a car and a horsebox trailer.
Select the option pointing to the 'PTRA' value, which is located in section F.3 of the vehicle registration document.
Section F.3 (PTRA) defines the vehicle's maximum train weight, whereas F.2 (PTAC) only limits the individual towing vehicle itself.
Discover the definition of PTRA, how it regulates the combined weight of a towing vehicle and its trailer, and why it is critical for French Code de la Route exams.
PTRA stands for Poids Total Roulant Autorisé, which translates to Gross Train Weight or Gross Combined Weight in English. It is an official regulatory limit established by the vehicle manufacturer and French homologation authorities (DREAL). This limit determines the maximum safe combined mass that your vehicle can pull and stop. It is a absolute mechanical and safety threshold, accounting for the capabilities of the engine, the durability of the transmission, and, most importantly, the braking performance of the towing vehicle.
You can find this value on your French vehicle registration document (carte grise) under section F.3. Regardless of how much cargo or passenger capacity your car technically has, you must never operate a vehicle and trailer combination that weighs more than this legal figure when placed on a scale.
One of the most common points of confusion on the French driving theory exam is the distinction between PTAC (Poids Total Autorisé en Charge - Gross Vehicle Weight) and PTRA.
To drive legally, you must respect all of these limits simultaneously. The actual weight of your car must not exceed its individual PTAC, the actual weight of the trailer must not exceed its individual PTAC, and the cumulative weight of both must not exceed the towing car's PTRA.
In France, the weights listed on your registration documents directly dictate which category of driving license you need to tow a trailer. Your PTRA is a key factor in these calculations, especially when combined with the maximum weights of your vehicles:
Exceeding the PTRA of a vehicle poses immense safety hazards on public roads. The braking systems of passenger cars are engineered to decelerate loads within specific limits. When a vehicle pulls an ensemble that exceeds its designated PTRA, stopping distances increase exponentially, brake pads can overheat and fail entirely (brake fade), and the vehicle's handling becomes highly unstable.
Additionally, pulling a load beyond the PTRA strains the vehicle's engine and transmission, leading to potential mechanical failure on inclines. From a legal standpoint, exceeding the PTRA can result in severe fines during police checkpoints, vehicle immobilization, and the complete invalidation of your insurance policy in the event of an accident.

Get clear answers to the most searched questions about Gross Train Weight (PTRA) in French driving theory for France. This FAQ explains the definition, real exam context, practical meaning, and common learner doubts to support confident theory test preparation.
PTAC (Poids Total Autorisé en Charge) is the maximum legal weight limit for a single vehicle on its own, including its load. PTRA (Poids Total Roulant Autorisé) is the maximum combined weight of both the towing vehicle and the trailer together.
You can find the PTRA printed on your vehicle's registration certificate (carte grise) in the official category marked F.3.
Yes. The relationship between your vehicle's PTAC weights and PTRA determines if a standard Category B license is sufficient, or if you need the B96 certificate (for total weights up to 4,250 kg) or a BE license (for setups exceeding 4,250 kg).
No. Your combined actual weight (the real weight of the car plus the real weight of the trailer on a scale) must never exceed the registered PTRA, regardless of whether the trailer is full or empty.
Exceeding the PTRA is a serious safety violation that can lead to heavy fines, vehicle immobilization, and insurance invalidation in the event of an accident.
