Vehicle registration: how to read and complete legend
Learn how to read your vehicle registration: complete guide to code legends, sections, and how it changes with the LPG system on your vehicle.
The registration certificate, also known as the vehicle registration card, is an essential document that accompanies every vehicle and certifies its roadworthiness. This document contains information about the vehicle, its owner and technical specifications.
It is mandatory to keep it in the car since, in case of control by law enforcement, it must always be shown together with the driver's license.
To prevent forgery, the registration certificate is printed on a special paper with security elements, making it difficult to forge.
Every motorist should know the meaning of the codes and information in the registration certificate, as it is useful not only for administrative operations, such as the transfer of ownership or overhaul, but also for understanding basic data related to the vehicle's characteristics so as to avoid bureaucratic problems and ensure that the data are correct.
Moreover, it is an essential aspect when buying a used car, as it allows you to verify that the information provided by the seller matches the official information.
In this guide, we will look in detail at the structure of the registration certificate and explain the complete code legend to help you interpret it with ease.
Structure of the registration certificate
The structure of the registration certificate is divided into 4 quadrants. The subdivision is designed to make reading simple and straightforward, so that it is easy to consult and allows for quick identification of necessary information, both for personal use and in the event of inspections by the competent authorities.
The front of the booklet contains the main information about the vehicle and its owner, while the back of the booklet contains technical details and data on revisions. Each section of the logbook is organized according to a codified scheme, established by European regulations, which ensures uniformity across EU member states.
We will explain all the details in it below.
Front of the registration certificate
On the front of the registration certificate we find four quadrants that enclose the main data about the vehicle and its owner. This page is particularly important because it provides the key information for identifying the vehicle and the owner, details that are essential for any administrative operation.
Each item listed on this page is governed by precise alphanumeric codes, which allow for the uniformity of registration documents at the European level.
First quadrant: Vehicle identification data
This section contains essential vehicle identification data, including license plate number, date of first registration, make, type, and trade name. These data are important to ensure that the vehicle is properly registered.
Second quadrant: Owner data
In this part we find information about the owner of the vehicle, such as first name, last name or company name, and residential address. This information allows the legal owner of the vehicle to be traced and is essential during operations such as the transfer of ownership or in case of administrative checks.
Third quadrant: Main technical data
Here are data on the vehicle's structure, including chassis number, maximum laden mass, and other technical parameters. Useful information that makes it possible to identify the technical specifications of the vehicle, both for checking its characteristics and to ensure that the vehicle complies with safety and environmental regulations.
Quadrant Four: Type Approval and Environmental Characteristics
This section contains information on the vehicle's pollutant emissions, fuel type, and type approval number. This data is particularly relevant for compliance with environmental regulations and for making sure that the vehicle meets the emission limits set by law.
Back of the the registration certificate
At the back of the the registration certificate we find four other quadrants that deal with administrative management and additional technical characteristics of the vehicle.
This section is particularly relevant for verifying the vehicle's compliance with current regulations, as it includes details on the inspection, overall mass, towing capacity, and other notations.
First quadrant: Overhaul and deadlines
This section provides information on mandatory overhauls, including the due date and vehicle category. Periodic overhaul is essential to ensure that the vehicle is in safe condition and meets environmental regulations.
Quadrant Two: Mass and Towing
This quadrant includes basic data on the vehicle's maximum allowable mass and towing capacity. It is here that we find the maximum towable mass with and without brakes, particularly important information for those who use the vehicle to transport trailers or caravans.
Quadrant Three: Seats and Specific Features
Here we find the total number of seats available in the vehicle, including the driver, and other specific details concerning the configuration of the passenger compartment. These details are relevant, for example, for checking the maximum allowable seating capacity and for any type-approval updates.
Fourth quadrant: Entries and administrative changes
The last section of the back of the vehicle registration book is devoted to official entries, which may relate to changes of ownership, changes of residence of the owner, structural changes to the vehicle, or other relevant changes. This part is useful to make sure that the registration is always up-to-date and correct about the administrative status of the vehicle.

How the registration certificate changes with an LPG system
With an LPG system installed after market, i.e., after the purchase of the vehicle, the registration certificate undergoes some changes following testing.
After the installation, the installing workshop puts a specific stamp on the registration certificate, with references to the “main” components installed.
Once the test has been passed at an Office of the Civil Motorization, an official sticker attesting to the approval of the installation is issued, to be applied directly to the vehicle registration.
An important detail to keep in mind concerns the installation of the system:
? In case of after-market installation, the P.3 (fuel type) code in the registration remains “Benz” (gasoline), even after the system is added.
? In case of installation from the manufacturer, the P.3 (fuel type) code will directly indicate “B/LPG,” signaling that the vehicle was born with mixed fuel.
Conclusion
In conclusion, understanding the vehicle registration document thoroughly allows you not only to handle your vehicle with greater awareness, but also to deal with any bureaucratic, administrative or technical procedure without any unforeseen problems.
Whether it is a simple overhaul, a transfer of ownership or the verification of environmental characteristics, being familiar with this document will help you move confidently through regulations and inspections.
The vehicle registration is your car's identity card, and knowing it thoroughly can really make a difference.
