A 12 m³ truck represents the most common size for an individual move or a medium volume delivery. The question of the necessary license always comes up, and the answer depends on a single technical criterion: the vehicle’s total authorized weight, not its volume.
GVW and volume: why the 12 m³ blurs the lines
The loading volume (12 m³) is not mentioned in any regulatory text regarding license categories. The Highway Code classifies vehicles according to their GVW (gross vehicle weight), expressed in tons and noted on the registration certificate.

A 12 m³ van can have a very variable GVW depending on the manufacturer and model. Some remain below the 3.5-ton threshold, while others exceed it. It is this data, and this alone, that determines the required license category. Before booking or purchasing, checking box F2 on the registration certificate settles the debate.
To fully understand the concrete implications before driving a 12m3 truck, it is essential to distinguish between two very different regulatory scenarios depending on whether the GVW is below or above 3.5 tons.

License B and 12 m³ truck: the 3.5-ton limit
License B allows the driving of any vehicle whose GVW does not exceed 3.5 tons, with a maximum of 8 passengers in addition to the driver. Most 12 m³ trucks offered for rent by mainstream companies fall into this category.
Since January 1, 2024, the minimum age to obtain a license B has been raised to 17 years with immediate independent driving after passing the exam. A 17-year-old can theoretically take the wheel of a 12 m³ van weighing less than 3.5 tons, provided they hold the license.

A common pitfall concerns the payload. A 12 m³ van under license B offers a payload that quickly decreases once the weight of the empty vehicle is subtracted from the GVW. Loading beyond the GVW noted on the registration certificate constitutes an offense, even if the license B is valid. Law enforcement checks this point during roadside weighings.
License C1 and C: when the GVW exceeds 3.5 tons
As soon as the GVW exceeds 3.5 tons, license B is no longer sufficient. Two categories then come into play:
- The C1 license covers vehicles with a GVW between 3.5 and 7.5 tons. Some 12 m³ trucks intended for professional transport fall within this range.
- The C license (known as “heavy vehicle”) allows the driving of vehicles over 7.5 tons GVW, which rarely concerns a 12 m³ but may apply to specific chassis-cabs equipped with a box of this volume.
- In both cases, the candidate must already hold a license B and undergo a mandatory medical check-up renewable every 5 years.
The minimum age for the C1 license is set at 18 years, while for the C license it is 21 years. The training includes a theoretical part and a specific practical test, distinct from those of the B license.
Renewal and medical examination
Heavy vehicle licenses (C, C1, and their E variations) are not issued for life. The validity is limited to 5 years, with the obligation to undergo a medical examination by an approved doctor for each renewal. This point is often overlooked by occasional drivers who obtain a C1 license for a specific need and then forget the deadline.
Truck license financing: what the CPF still covers
Since May 2024, the rules for using the CPF (Personal Training Account) have been tightened for light vehicle licenses. However, heavy vehicle licenses remain eligible for CPF funding without a specific ceiling and without co-financing obligations.
This distinction is worth noting: an employee wishing to obtain a C1 license for professional reasons can mobilize their CPF without the restrictions applied to the B license since the 2024 reforms. The main condition remains that the training is provided by a Qualiopi certified organization.
What the CPF does not finance
The costs of the medical examination, any additional driving hours outside the initial package, and the ANTS file fees are not covered. The actual cost of training therefore exceeds the amount displayed by the organization on the Mon Compte Formation platform.
12 m³ truck with trailer: the case of licenses B96 and BE
Attaching a trailer to a 12 m³ van changes the equation. The B license alone allows for a coupling whose combined GVW (vehicle + trailer) does not exceed 3.5 tons, or up to 4.25 tons with the additional B96 training (7 hours, without examination).
Beyond that, the BE license becomes mandatory. It allows for a combination where the trailer exceeds 750 kg GVW and the total combined weight exceeds 4.25 tons. This scenario arises when a professional tows a platform or utility trailer behind a fully loaded van.
- Combined GVW below 3.5 tons: B license sufficient
- Combined GVW between 3.5 and 4.25 tons: B license with B96 training
- Combined GVW above 4.25 tons: BE license mandatory
The required license category for a 12 m³ truck boils down to a preliminary check: the GVW on the registration certificate. A standard rental van remains within the scope of the B license, while a professional vehicle of the same volume may shift to C1.
Checking box F2 before signing a rental or purchase contract avoids driving without a valid license, an offense punishable by one year in prison and a €15,000 fine.
