Buying a car is often accompanied by a desire to expand its functionality, and one of the popular solutions is installing a towbar. Car owners planning to transport caravans, boats or snowmobiles immediately face bureaucratic issues. Many are still confident that any design change requires a complex approval procedure, but the legislation has its own nuances.
Registration question tow bar in the traffic police depends on several factors, the main of which is the type of device itself and the availability of relevant documents from the manufacturer. If you simply bolt a piece of hardware to a frame without certificates, this will be considered a violation. However, the legal way to install equipment is much simpler than it seems at first glance, and does not always require a visit to an inspector.
In this article we will analyze all aspects of legalizing additional equipment, the necessary paperwork and the consequences of ignoring the rules. You will find out when you can do without going to the MREO, and in what cases making changes to the PTS is a mandatory requirement of the law.
Is it necessary to register a tow bar by law?
According to the current legislation of the Russian Federation, any change in the design of the vehicle must be approved. However for towing devices (TSU) an exception is made if certain conditions are met. The main regulatory act here is the Technical Regulations of the Customs Union “On the safety of wheeled vehicles”.
Registration is not required if the car manufacturer provides for the installation of a tow bar in the model documentation. In this case, the plant has already carried out the necessary tests and certification. All you have to do is confirm that the installed equipment meets the safety requirements for your specific car modification.
If the documents for the car do not mention the possibility of installing a trailer hitch, or you are using non-certified equipment, then formally this is a design change. In this case, a full procedure for making changes through the testing laboratory and the traffic police is required. Most modern foreign cars are marked accordingly in the instruction manual.
⚠️ Attention: Installing a towbar that does not have a certificate of conformity, or installing a device on a car where such an option is not structurally provided for, is equivalent to making changes to the design without permission. This threatens to cancel the vehicle registration.
Requirements for towing devices
To ensure that traffic police inspectors do not have questions, the installed equipment must be certified. Every legal tow bar must be marked with the type, capacity and date of manufacture. The absence of a brand or tag is the first sign of an illegal product that is better not to buy.
It is important that the trailer hitch is suitable not only for the car model, but also for the specific year of manufacture and body type. Manufacturers often change the geometry of bumpers and side members, so there are practically no universal solutions “for everyone”. Certificate of Conformity must be certified by the seal of the manufacturer or seller and contain a link to the technical regulations.
Where can I find information about towbar compatibility?
Your vehicle's owner's manual will often have a "Towing" or "Options" section. The permissible weights of the trailer and sometimes even the article numbers of the recommended coupling devices are indicated there. Information can also be found on the automaker’s official website in the technical specifications section.
When purchasing, pay attention to the maximum vertical load on the ball and the weight of the towed trailer. Exceeding these indicators is not only dangerous, but also legally makes the operation of such a tandem illegal. Documentation must be in Russian or have a notarized translation.
- 🚗 Availability of markings with strength class and production date on the metal part of the device.
- 📄 Full set of documents: product passport, EAEU certificate of conformity, installation instructions.
- 🔧 No damage or corrosion on new parts, high-quality painting of elements.
Necessary documents for registration
Collecting a package of documents is the most important stage, which allows you to avoid problems when communicating with the traffic police. If you plan to legalize the towbar or simply have papers on hand when checking, you will need the original certificate of conformity. Inspectors may be reluctant to accept copies, even certified ones, although by law they are valid if they are legible.
You will also need a purchase and sale agreement or a sales receipt confirming that the equipment was purchased legally. The receipt must include your vehicle's VIN or a clear model for which the device is intended. This links a specific towbar to a specific vehicle in the eyes of the law.
☑️ Documents for roadside checks
In some cases, if the installation was carried out in a specialized service, you will be given a certificate of completion of work. This document is not mandatory for the kit you carry with you, but is extremely important when registering changes with the traffic police, if required. The certificate confirms that the installation was carried out professionally and in compliance with technology.
| Document type | Original or copy | Where to get it | Validity period |
|---|---|---|---|
| Certificate of Conformity | Copy (certified) | From the seller/manufacturer | Indefinitely (for model) |
| Product data sheet | Original | Complete with tow bar | Indefinitely |
| Installation certificate | Original | At the service center | Indefinitely |
| Check/Contract | Original/Copy | Auto parts store | Warranty period |
Installation and testing procedure
Installing a tow bar yourself is possible if you have the necessary skills and tools. However, for legal purity and to maintain the warranty on the car (if it is new), it is better to contact a specialized service. Craftsmen know where to drill holes so as not to damage bumper reinforcements or safety elements.
After installation, it is necessary to check the electrical part. The socket connection must be made via a matching unit (Smart Connect), especially on vehicles with multiplex wiring. Directly cutting into wires can lead to on-board computer errors and fire, which is also a violation of safety regulations.
Use a matching block when connecting the towbar electrics. This will protect the electronic systems of a modern car from overloads and errors that can occur when connecting a conventional trailer lamp.
A visual inspection after installation should show that there are no gaps between the body and the device and that the bolted connections are securely fastened. All threaded connections must be tightened to the torque specified in the instructions, and preferably locked. Towbar play is unacceptable.
⚠️ Attention: When drilling holes in the side members, be sure to treat the cuts with an anti-corrosion compound. Ignoring this step will cause rust to quickly develop in hidden frame cavities, making it difficult and expensive to correct in the future.
Fines and liability for lack of registration
Lack of documents for a tow bar or installation of uncertified equipment entails administrative liability. The traffic police inspector has the right to issue a fine under Part 1 of Article 12.5 of the Code of Administrative Offenses of the Russian Federation for driving a vehicle in the presence of malfunctions or conditions, the list of which is established by the Basic Provisions for the Admission of a Vehicle.
The fine is 500 rubles. The amount seems insignificant, but that is not the problem. The main threat is that the inspector may prohibit further operation of the vehicle until the malfunction is eliminated. This means removing the license plates and towing the car to the impound lot.
Additionally, if you are involved in an accident with a trailer and the towbar is not registered or has no documentation, the insurance company may refuse to pay out, citing an illegal modification to the design. Civil liability in this case, it falls entirely on the owner of the car, which can result in millions of dollars.
- 💰 Fine 500 rubles under Art. 12.5 Code of Administrative Offenses of the Russian Federation.
- 🚫 Prohibition on the use and removal of state registration plates.
- 🏥 Refusal of the insurance company to pay compensation for an accident involving a trailer.
Making changes to PTS and STS
Is it necessary to include a tow bar in the PTS and STS? If you have a complete package of documents in your hands (a certificate for a trailer hitch, a certificate for a car with a mark on the possibility of installation, an installation certificate), then make changes to the registration data not required. You simply carry copies of documents with you.
However, many owners prefer to make an entry in the STS to exclude any questions from the police. To do this, you need to go through the procedure of registering changes in the design with the traffic police. This will require visiting a testing laboratory, obtaining a conclusion and paying state fees.
If you have a full package of certificates from the manufacturer of the car and the towbar, making changes to the PTS and STS is not mandatory, but can simplify communication with the traffic police.
The procedure for making changes takes time and costs money (from 10 to 30 thousand rubles depending on the region and laboratory). A record of the presence of a trailer hitch will appear in the “Special notes” column in the STS. After this, you can safely transport the trailer without fear of quibbles, since the presence of the towbar will be recorded in the traffic police database.
Do I need to remove the towbar if I'm not driving a trailer?
No, you do not need to remove the towbar if it is installed legally and has documents. However, if the tow bar is removable and protrudes greatly beyond the dimensions, creating a danger for pedestrians when parking, it is better to dismantle it. The law does not require the removal of the trailer hitch, but does require that it does not impair safety.
Is it possible to install the tow bar yourself and get the documents?
Theoretically, it is possible, but to register changes with the traffic police (if it is needed), an installation certificate will be required from an organization that has a license for this type of work. It will be more difficult and expensive to legitimize a self-installed tow bar through a laboratory, as additional checks will be required.
What to do if the towbar certificate is lost?
You must contact the manufacturer or official dealer where the device was purchased. They can issue a certified copy of the certificate. Without this document, the towbar is considered to have no safety confirmation, which is equivalent to an unregistered design change.
