A trike built from a Gold Wing or a Harley sits proudly in the garage, the kit is installed, and the welds are clean. What remains is the administrative wall. In France, riding a non-homologated motor tricycle exposes you to vehicle impoundment and a fine. The procedure goes through the DREAL, requiring a solid technical file and proper registration. Here, we detail the points where things really get stuck.
DREAL Technical File: What Blocks Artisan Trike Projects
Before even making an appointment, we prepare the file. This is where most projects derail, especially when the transformation is artisanal. Since 2022-2023, several DREALs have been applying the European framework for category L5e (motor tricycles) and directive 168/2013/EU more strictly. The old DRIRE letters found on forums are no longer considered as binding references.

Specifically, the DREAL expects a technical file with dimensioned plans, welding certificates, and strength calculations. A homemade welded swingarm without documentation will no longer pass. Serious professional workshops now refuse certain projects due to the inability to produce these justifications. If starting from a commercial kit-trike, the manufacturer usually provides a usable technical bundle. If you are building it yourself, you need a design office or an engineer capable of signing off on the calculations.
To better understand the applicable regulations, particularly what license is needed for a trike on Autos Actus, category L5e imposes precise requirements regarding braking, stability, emissions, and noise.

- Dimensioned plans of the chassis and rear axle, with dimensional tolerances compliant with manufacturer standards
- Material certificates (steel, aluminum) and reports of welds performed by a qualified welder
- Strength calculation note for the connecting arm and rear braking system
- Proof of compliance for tires and lights (E or e homologation)
Isolated Reception (RTI): The Mandatory Step at the Technical Prefecture
Once the file is complete, a request for isolated reception must be submitted to the DREAL of your region (or DRIEAT in Île-de-France). The RTI is the administrative act that certifies that the vehicle, taken individually, complies with technical safety and emissions regulations.
The vehicle is presented physically. The inspector checks the correspondence between the paper file and reality: geometry, anchor points, lighting, manufacturer plate, serial number. Feedback on this point varies among DREALs, with some requiring additional tests (braking on a bench, axle weighing), while others are satisfied with a thorough visual inspection.
Actual Costs and Delays of the RTI
The homologation budget is a line item that purely administrative guides often forget to quantify. Specialized actors like Soopa/MTM France indicate that the homologation item represents several hundred euros, including the fees for preparing the file and the DREAL submission costs. This amount is in addition to the price of the kit and the labor for the transformation.
In terms of delays, it generally takes several weeks between the submission of the file and the appointment for the vehicle presentation. During busy periods, this can stretch further. It’s best to call the DREAL in your department before planning everything.
Trike Registration After Homologation: Certificate of Conformity and Registration Document
Once the RTI is validated, the DREAL issues a receipt report. This document is the key to obtaining the registration certificate (carte grise). Without it, no steps at the prefecture or on the ANTS website will succeed.
The registration file includes:
- The RTI report issued by the DREAL
- A proof of identity and residence of the owner
- The certificate of transfer if the base vehicle was purchased used
- The old registration document of the original motorcycle (crossed out and signed)
- The completed Cerfa form 13750
The vehicle will be registered in the motor tricycle category (L5e) on the registration document. The mention L5e on the registration document determines the type of license required and the applicable insurance regime. An error in category at this stage complicates everything later on.
Technical Inspection and Insurance: Two Often Overlooked Obligations for a Trike
A homologated L5e trike is subject to periodic technical inspection, just like any motorized vehicle in this category. The first inspection occurs within the regulatory deadlines after the first registration. It takes place at an approved center for L category vehicles.
For insurance, a trike is neither a motorcycle nor a car in the eyes of insurers. Some motorcycle contracts cover L5e tricycles, while others do not. It is essential to check that the coverage explicitly mentions the vehicle category as it appears on the registration document. An unregistered or misclassified trike may find itself without coverage in the event of a claim.
Driving Without Homologation: The Concrete Risks
Driving a trike without a valid RTI and registration document exposes you to immediate vehicle impoundment by law enforcement. The absence of homologation also nullifies the insurance contract, leaving the driver personally liable for any damages caused.
The administrative path for a trike in France remains demanding, but each step protects both the driver and other road users. Preparing the technical file in advance with a professional or a documented kit avoids most back-and-forth with the DREAL, and this is often where the success of the project is determined.
