Installing a towbar on a car is not just a technical modification, but a change in the design of the vehicle, which requires mandatory registration with the traffic police. Without proper legalization, the owner will face fines of up to 5,000 rubles, problems when passing technical inspection, and even a ban on operating the car. In this article we will analyze all stages of towbar design — from choosing certified equipment to obtaining new documents, and we will also tell you about hidden nuances that are not voiced in the MREO.

Many motorists mistakenly believe that it is enough to simply screw on the towbar and get a certificate from a service center. In practice, the process includes checking the conformity of the equipment GOST R 41.55-2005, making changes to PTS and STS, as well as passing a technical inspection. We have collected up-to-date information for 2026, including changes in traffic police regulations and new documentation requirements.

1. When is it necessary to register a towbar with the traffic police?

Not every tow bar requires registration with the State Traffic Inspectorate. According to Order of the Ministry of Internal Affairs No. 399, registration is necessary only in two cases:

  • 🔧 Installing a towbar on a car, where it is not provided by the manufacturer (no fastenings under the bumper, no electrical connector).
  • 📋 Replacing the standard towbar with a model with other technical characteristics (for example, increased load capacity or modified mounting geometry).

If your vehicle was originally equipped with a factory towbar (for example, Volkswagen Amarok or Mitsubishi L200), but you dismantled it and are now installing it back - no registration required. It is enough to keep the factory documentation.

Important: even if the towbar removable, but is not provided for by the design of the car, it still needs to be legalized. Traffic police inspectors have the right to check the presence of entries in the STS when stopping.

2. What documents are needed to register a tow bar?

To legalize a towbar at the traffic police, you will need a package of documents. It can be divided into three groups:

  1. Documents for the car:
    • 📄 Vehicle Passport (PTS) - original.
    • 📄 Vehicle Registration Certificate (CTC).
    • 📄 OSAGO policy (current).
  2. Documents for the towbar:
    • 📜 Certificate of Conformity GOST R 41.55-2005 or Regulations of the Customs Union TR CU 018/2011.
    • 📄 Declaration of conformity (if the tow bar is imported).
    • 📋 Product passport indicating the model and technical parameters.
  • Additional papers:
    • 📝 Application for changes to the design of the vehicle (the form is issued by the MREO).
    • 📑 Conclusion of preliminary technical examination (if required).
    • 💰 Receipt for payment of state duty (800 rubles for making changes to the PTS).

    Pay special attention certificate for tow bar. It must be valid and issued by an accredited body. Check that the document contains:

    • 🔹 Make and model of the car for which the towbar is intended.
    • 🔹 Maximum vertical load (D-value).
    • 🔹 Mounting type (removable/non-removable).
    💡

    Before purchasing a towbar, check its availability in register of the Federal Agency for Technical Regulation. This will save time when registering with the traffic police.

    3. Step-by-step instructions: how to register a tow bar with the traffic police

    The registration process consists of 5 key stages. Let's look at each in detail:

    Install the towbar in a certified service|Receive a diagnostic card with changes|Pass a preliminary examination (if necessary)|Submit documents to the MREO|Receive new PTS and STS-->

    Step 1. Installation of the towbar in a certified service

    Installation must be carried out service center with a license to work on modifications to the vehicle design. After installation you will be given:

    • 📋 Certificate of completed work indicating the towbar model and certificate data.
    • 📄 A copy of the service center license.
    • 🔌 Electrical wiring diagram (if the connector was connected).

    Step 2. Passing technical inspection

    With the towbar installed you need to go unscheduled inspection at an accredited point. The inspector will check:

    • 🔧 Compliance of the towbar with the certificate.
    • 💡 Correct electrical wiring connection (operation of brake lights, dimensions, trailer fog lights).
    • 📏 Mounting geometry (should not protrude beyond the dimensions of the car by more than 400 mm).

    Based on the result, it is issued diagnostic card with a note indicating the changes made. The card is valid for 6 months (until registration with the traffic police).

    Step 3. Preliminary examination (if necessary)

    If the traffic police inspector doubts the safety of the changes, he can send the car to preliminary technical examination. It is carried out in specialized laboratories (for example, US or FSUE "Standardinform"). The cost of the examination is from 5,000 to 15,000 rubles.

    Expertise is required in the following cases:

    • 🚛 Installing a towbar on a category car B, if its weight with a trailer exceeds 3500 kg.
    • 🔧 Use of non-standard fasteners (for example, welding instead of bolted connections).
    • 📋 Lack of a towbar certificate in the FSA register.

    Step 4. Submitting documents to the MREO

    The collected package of documents is submitted to any traffic police department (by appointment via State Services portal). In your application please indicate:

    • 📝 Make and model of towbar.
    • 📝 Certificate data.
    • 📝 Name of the service center that performed the installation.

    The application review period is up to 30 days. During this period, the inspector may request additional documents or send for a re-inspection.

    Step 5. Obtaining new documents

    Once the changes are approved, you will be given:

    • 📄 New PTS with an entry in the "Special Notes" section (for example: "A tow bar is installed Bosal A000-572-575, certificate No. ROSS RU.AYA56.B00123").
    • 📋 New STS with a note indicating the changes made.
    • 📋 Certificate of conformity of vehicle design (issued on a separate form).
    💡

    Without making changes to the PTS and STS, the towbar is considered illegal, even if you have all the certificates and installation certificates.

    4. How much does it cost to register a tow bar with the traffic police?

    The total cost of registration consists of several cost items. The table shows the average price range for Moscow and the regions for 2026:

    Expense item Cost, ₽ Notes
    Installation of a towbar in a service 3000–8000 Depends on the car model and towbar type (removable/non-removable)
    Certified towbar 5000–20000 Price varies depending on brand (Bosal, Thule, Westfalia)
    Technical inspection 800–1500 Cost of diagnostic card with changes
    State duty for making changes to the PTS 800 Paid through State Services (30% discount) or at the bank
    Preliminary examination (if necessary) 5000–15000 Required in 10–15% of cases

    Total minimum registration cost - from 9600 rubles (without examination). The maximum can reach 40,000–50,000 rubles for premium cars with expensive towbars.

    How to save on registration?

    1. Buy a towbar with a ready-made certificate (check for availability in the FSA register).

    2. Install in services accredited by official dealers - they often give discounts on work.

    3. Pay the state fee through State Services (30% discount).

    4. If the towbar is removable, register it as “temporary equipment” (confirmation of the possibility of quick dismantling is required).

    5. Fines for an unformed tow bar

    Operating a vehicle with an illegal towbar is equivalent to introducing unapproved changes to the design of the vehicle. According to Art. 12.5 Code of Administrative Offenses of the Russian Federation, the following sanctions are provided for this:

    • 🚔 Fine 500 rubles — if the tow bar is installed, but not connected to the electrical wiring (the trailer light alarm does not work).
    • 🚔 Fine 5000 rubles — if the towbar is not included in the vehicle title, but is used to tow a trailer.
    • 🚫 Prohibition on exploitation - if the inspector reveals that the towbar does not comply with the certificate or that the fastening geometry is violated.

    In addition, when passing a technical inspection with an unformed towbar, you will refuse to issue a diagnostic card, which automatically makes it impossible to purchase a compulsory motor liability insurance policy.

    ⚠️ Attention! If you are involved in an accident with a trailer connected to an unregistered tow bar, the insurance company may refuse to pay under MTPL/CASCO, citing a violation of the operating conditions of the vehicle.

    6. Common mistakes when designing a tow bar

    Even with careful preparation, motorists make mistakes that lead to denial of registration. Here are the most common:

    • 🔴 Buying a tow bar without a certificate — sellers often offer “analogues” without documents at a low price. Such products will not pass the traffic police inspection.
    • 🔴 Self-installation — even if you installed the towbar according to the instructions, it will not be registered without a certificate from a certified service.
    • 🔴 Car model mismatch — the towbar certificate must be issued specifically for your make and model of vehicle. For example, a towbar for Toyota Hilux not suitable for Toyota RAV4, even if the fastenings match.
    • 🔴 Lack of wiring diagram — the inspector may require a document confirming the correct connection of the connector.

    Another typical problem is incorrect filling out of the application. For example, if in the “Type of design change” column you indicate “installation of a tow hitch” instead of “installation of a towbar,” this may become a reason for refusal.

    ⚠️ Attention! If you change the car, but leave the tow bar, it will have to be re-registered again. The certificate and entries in the PTS are tied to a specific vehicle.

    If the car belongs to a company, the process of designing a towbar has several nuances:

    • 📋 Power of attorney — the employee involved in registration must have a notarized power of attorney to represent the interests of the organization.
    • 📄 Additional documents — you will need an extract from the Unified State Register of Legal Entities and a copy of the company’s charter.
    • 💰 Payment of state duty — legal entities are not entitled to a 30% discount when paying through State Services.
    • 📊 Accounting — the cost of the towbar and its installation can be written off as expenses for the modernization of fixed assets (according to PBU 6/01).

    The processing time for legal entities may increase to 45 days, as additional verification of documents for authenticity is required.

    Important: if the car is leased, installing a towbar will require written consent of the lessor. Without it, changes to the vehicle design are prohibited.

    FAQ: Frequently asked questions about towbar design

    ❓ Do I need to arrange a towbar if I don’t use it (just installed)?

    Yes, even if the towbar is not in use, its presence on a car where it is not provided by the factory requires registration. The traffic police inspector may issue a fine for unapproved design changes.

    ❓ Is it possible to arrange a tow bar through State Services?

    On the State Services portal you can make an appointment with the traffic police and pay the state fee with a 30% discount. However, you cannot submit documents remotely—you will need to visit the MREO in person.

    ❓ How long does registration take?

    The period depends on the workload of the traffic police and the need for examination:

    • Without examination - 7–14 days.
    • With examination – 20–30 days.

    You can speed up the process if you prepare all the documents in advance and make an appointment through State Services.

    ❓ What to do if the traffic police refused to register?

    If refused, you must be given written justification indicating the reasons. Most often they are refused due to:

    • The towbar does not comply with the certificate.
    • Errors in filling out the application.
    • Lack of installation certificate from a certified service.

    You can eliminate the shortcomings and resubmit the documents or appeal the refusal in court (according to Art. 30.1 Code of Administrative Offenses of the Russian Federation).

    ❓ Do I need to redo the OSAGO after installing the tow bar?

    No, you do not need to renew your MTPL policy. However, the next time you renew your insurance, notify the company about changes in the design of the vehicle - this may affect the cost of the policy (usually increases by 5-10%).
