Towing a vehicle is a situation that every driver faces sooner or later. But even experienced car owners do not always remember the nuances of the rules regarding alarm on a towed vehicle. A mistake here can cost not only a fine, but also create a real danger on the road. According to Traffic rules of the Russian Federation (clause 7.1), the requirements for the use of emergency lights when towing are strictly regulated - and they cannot be ignored.

In this article we will analyze the only legal case when the hazard warning lights on a towed mechanical vehicle must be turned on, and also consider exceptions, fines and typical driver mistakes. We will pay special attention motor vehicles (unlike trailers), since the rules are different for them. If you have ever towed a car using a flexible or rigid hitch, this information will help you avoid conflicts with inspectors and accidents.

Traffic rules 2026: what the law says about emergency lights when towing

The main regulation governing the use of hazard warning lights when towing is Traffic rules of the Russian Federation, namely clause 7.1. It clearly states:

⚠️ Attention: The hazard lights must be turned on only on a towed motor vehicle (not on a trailer!) when driving flexible hitch or method partial loading. The hazard lights should not turn on on the towing vehicle.

Key points of this rule:

  • 🔹 Mechanical vehicle - these are cars, motorcycles, tractors and other equipment with an engine (as opposed to trailers, for which the requirements are different).
  • 🔹 Flexible hitch — towing on a cable or chain (length from 4 to 6 meters according to traffic regulations).
  • 🔹 Partial loading — when the front or rear of the towed car is on the tow truck platform (for example, a front-wheel drive car with the front wheels raised).
  • 🔹 Rigid coupling - there's an emergency light here not required, since the design ensures synchronous movement of both vehicles.

Important: if the towed vehicle faulty (for example, turn signals or brake lights do not work), then The hazard warning lights must be turned on in any case, regardless of the type of coupling. This is stated in clause 7.3 of the traffic rules as a measure of additional warning to other road users.

Why is a hazard warning system mandatory only on a flexible hitch?

The logic behind the requirement lies in physics of motion and security. When towing with a flexible hitch:

  • 🚗 Delayed reaction: the towed vehicle begins to brake or turn later than the towing vehicle due to slack in the cable. The emergency light signals other drivers about non-standard dynamics.
  • 💥 Risk of breakage: if the cable breaks, the activated emergency lights will help other road users react faster to the suddenly stopped vehicle.
  • 👀 Visual warning: Flashing lights attract attention, especially at night or in poor visibility conditions.

When rigid coupling Both vehicles move synchronously, so no additional warning is required. But when partial loading emergency lights are needed because:

  • 🔧 Some of the wheels of the towed vehicle may be blocked or rotate asynchronously.
  • 🚛 Visually, this design is perceived as “non-standard”, and the flashing lights help other drivers understand that there is a tow ahead, and not a regular load.
💡

If you tow a car on a flexible hitch in the dark, additionally attach a reflective element (for example, a red flag) to the cable. This is not a traffic obligation, but greatly increases visibility to other drivers.

Fines for violation: what is the penalty for turning off the emergency lights

Failure to comply with the requirements for the use of hazard warning lights when towing is classified as violation of cargo transportation rules (article 12.21 Code of Administrative Offenses of the Russian Federation). Sanctions depend on the consequences:

Violation Fine (rub.) Additional measures
No emergency lights on the towed vehicle (flexible coupling/partial loading) 500 Warning or fine
Faulty emergency lights (lights do not blink) 500 Request for troubleshooting on site
Violation caused an accident 1 000–1 500 Vehicle evacuation is possible
Towing with impaired driving while intoxicated 30,000 + deprivation of rights Vehicle arrest

The traffic police inspector has the right to stop the towing column if:

  • 🔦 The hazard warning light is not turned on (with a flexible hitch).
  • 🚨 The lights flash asynchronously or at the wrong frequency (according to GOST, the frequency should be 1-2 flashes per second).
  • 📏 The length of the cable does not meet the standards (less than 4 or more than 6 meters).
⚠️ Attention: If the towed vehicle is not equipped with a working hazard warning system (for example, after an accident), then according to clause 7.3 of the traffic rules must be installed on it warning triangle (red triangle) at the back. This does not cancel the requirement to turn on the emergency lights if they are working!

Exceptions: when the emergency lights do not need to be turned on

There are situations when hazard warning lights are not required on a towed vehicle even with flexible coupling:

Towing with a rigid hitch | Towing a trailer (not a mechanical vehicle) | Towing during daylight hours on a deserted road (but this is risky!) | Towing special equipment (for example, tractors) along an agreed route-->

Let's take a closer look:

  1. Rigid coupling: here both vehicles are connected by a rigid structure (for example, a metal bar), which eliminates the “yaw” of the towed vehicle. Example: towing Volkswagen Passat B6 using a rigid coupling Bosch.
  2. Trailers: emergency lights are never required on them, since they are not mechanical vehicles (they don't have an engine). The exception is if the trailer is carrying dangerous goods (in which case orange flashing lights are required).
  3. Special equipment: towing of tractors, combines or other agricultural equipment is often carried out along agreed routes with escort. In such cases, separate rules may apply.

However, even in these cases recommended turn on the emergency lights if:

  • 🌧 Visibility less than 300 meters (rain, fog, snowfall).
  • 🌃 Towing occurs in the dark.
  • 🚧 The movement is carried out along a highway with an intense flow of cars.
What to do if the emergency light is broken?

If the hazard warning lights on the towed vehicle do not work, then according to clause 7.3 of the traffic rules required:

1. Install a warning triangle (red triangle) at the rear.

2. If possible, attach reflective elements (red or orange) to the cable.

3. Drive at a speed of no more than 40 km/h and only in the far right lane.

Otherwise, the traffic police inspector may prohibit towing until the problem is eliminated.

Typical driver mistakes when towing

Even experienced motorists make mistakes related to hazard warning lights. Here are the most common:

  1. Turn on the emergency lights on the towing car

    This is a violation! According to traffic regulations, they should only flash rear lights of a towed vehicle. On a towed vehicle, the hazard lights make it difficult for other drivers to understand when you are actually braking or turning.

  2. Using an uncertified cable

    The cable must be orange or red with reflective elements. Length - from 4 to 6 meters. Unmarked homemade ropes or chains are prohibited.

  3. They do not check the serviceability of the hazard lights before towing

    There are times when the hazard lights turn on, but only one turn signal blinks (for example, due to a burnt-out lamp). This is equivalent to its absence!

  4. Towing with ignition off

    On many modern cars (for example, Toyota Corolla E210 or Hyundai Solaris) the emergency lights only work when the ignition is on. If you turn it off, the lights will go out and you will receive a fine.

Another common mistake is towing a car with automatic transmission on a flexible hitch. This can lead to damage to the box, since the oil does not circulate when the engine is turned off. In such cases it is mandatory partial loading or a tow truck.

1. The hazard warning system is working (turn it on and walk around the car).

2. The presence of a warning triangle in the trunk (in case of breakdown).

3. Condition of the cable (are there any breaks or knots).

4. Oil level in the automatic transmission (if you are towing a car with an automatic transmission).-->

Practical tips: how to tow correctly

To avoid fines and accidents, follow this algorithm:

  1. Preparing the towed car:
    • 🔑 Insert the key into the ignition and turn it to position ACC or ON (so that the emergency lights work).
    • 🔦 Check if the brake lights and turn signals are on (if not, use the warning triangle).
  2. Vehicle connection:
    • 🔗 Secure the cable to the special eyes (not to the bumper!).
    • 📏 Adjust the length of the cable: it should be taut, but not too tight.
  • Movement:
    • 🚦 Start moving smoothly, without jerking.
    • 📉 Speed no more than 50 km/h (and on highways no more than 40 km/h).
    • 🔄 Stop every 10-15 minutes to check the cable fastening.

    If you are towing car with automatic transmission, required:

    • 🔧 Move the selector to position N (neutral).
    • 🛢 Check the oil level in the box (if towing over a distance of more than 50 km, topping up may be required).
    • 🚛 Prefer partial loading or tow truck if the distance is more than 30-40 km.

    For towing in dark time of day additionally:

    • 💡 Turn on the side lights on both vehicles.
    • 🔦 Use a flashlight with a red light on a cable (according to GOST R 41.69-99).

    Frequently asked questions about towing and emergency equipment

    Do I need to turn on the hazard lights if I'm towing a motorcycle?

    Yes, if the motorcycle is towed using a flexible hitch (for example, using a cable behind the frame). A motorcycle is mechanical vehicle, so the rules are the same as for cars. If towing is carried out using the partial loading method (for example, the front wheel is raised on a platform), emergency lights are also required.

    Is it possible to tow a car with inoperative hazard lights?

    Technically possible, but only if you install warning triangle on the back of the towed vehicle and will move at a speed of no more than 40 km/h. However, the traffic police inspector may demand that the fault be corrected on the spot or prohibit towing if he considers it dangerous (for example, in poor visibility conditions).

    What to do if the cable breaks while towing?

    Immediately turn on the hazard warning lights on both vehicles and place a warning triangle at a distance of at least 15 meters (in a populated area) or 30 meters (outside the city). After this, re-tie the cable or replace it. It is prohibited to continue driving with a broken cable!

    Do you need an emergency warning light when towing on a tow truck (full load)?

    No, if the car is completely loaded onto the tow truck platform (all wheels do not touch the road). In this case it is considered cargo, and not a towed vehicle. However, if the method is used partial loading (for example, only the front or rear axle on the platform), then emergency lights are required.

    Is it possible to tow a car with a trailer?

    Yes, but only if:

    • 🚗 The towing vehicle has a permitted maximum weight that exceeds the weight of the towed vehicle + trailer.
    • 🔗 A rigid hitch is used (a flexible one is prohibited when towing with a trailer).
    • 💡 The side lights on the trailer must be turned on, and the hazard lights on the towed vehicle (if the hitch is flexible).

    Towing with a trailer is considered a difficult maneuver and requires special care.
