In a major change affecting thousands of trailer owners, the State is proceeding with new legislation, as Law 5290/2026 introduces for the first time a clear and mandatory framework for the legalization of trailers in categories O1 and O2.
This regulation provides a definitive solution to a long-standing issue, as until now many trailers—especially those used for transporting boats, jet skis, or motorcycles—were operating with a Special Towing Note (E.S.R.) without having a license or registration plates.
Mandatory Technical Inspection by KTEO
A central role in the new system is assigned to KTEO (Vehicle Technical Inspection Centers), which will now be responsible for conducting a special technical inspection for trailers.
This inspection aims to:
Confirm technical suitability
Enhance road safety
Establish a unified and reliable inspection system
The process will be further specified through a ministerial decision to ensure uniform implementation without ambiguity.
The Process for Owners
To legalize a trailer, owners must follow specific steps:
Gather the required documents (such as the E.S.R.)
Issue an electronic fee (e-paravolo) of €200
Undergo a special technical inspection at a KTEO
Submit an application to the competent Regional Transport and Communications Authority
The application is submitted once, without requiring physical presence, and applies to one vehicle for private individuals or up to 30 vehicles for businesses.
What Changes in Practice
The most important change is that:
👉 No trailer can circulate without a license and registration plates.
This means that the previous system using the Special Towing Note is no longer sufficient.
In case of non-compliance, penalties will be imposed according to the Road Traffic Code.
Technical Specifications and Safety
Beyond legalization, trailers must meet basic technical requirements, such as:
Maximum weight up to 3,500 kg
Mandatory technical inspection for trailers over 750 kg
Proper lighting and reflectors
Braking system where required
Secure loading using nets or straps
Good condition of tires and components
These specifications aim to reduce accidents and ensure safe transport of loads.
When It Comes into Force
The implementation of the new framework begins on April 30, 2026, subject to the issuance of the relevant ministerial decision that will define the details of the technical inspection.
A Step Toward Safety and Legality
The new regulation is expected to bring order to a field that has long operated without clear rules. With the involvement of KTEO and mandatory licensing, the system becomes safer, more transparent, and more functional for all road users.
🧾 Brief Summary
Law 5290/2026 establishes, for the first time, a clear framework for the legalization of trailers (categories O1 and O2), which until now operated with a Special Towing Note (E.S.R.) without license plates.
Key changes include:
KTEO centers carry out the special technical inspection
A €200 fee and application to the Region are required
Circulation without a license and plates is prohibited
The aim of the new framework is to ensure safety, technical compliance, and a unified legal treatment of trailers.
At the same time, trailers must comply with specific technical standards (weight, dimensions, lighting, brakes, safety, etc.), in line with international practices.
