Every driver must know in which cases driving a vehicle poses a real threat to life. There is a clear list of malfunctions in which the operation of the vehicle is prohibited completely or temporarily until the breakdown is eliminated. Ignoring these rules not only entails administrative liability, but also creates a direct danger on the road.
In this article we will examine in detail Section 2 “General Provisions” of the Road Traffic Rules, as well as “Basic provisions for the approval of vehicles for operation.” Brake system and steering are key components whose failure is unacceptable. You will learn to quickly diagnose critical problems and understand when the traffic police inspector has every right to prohibit you from further driving.
Road safety depends on the technical serviceability of each participant in the process. According to current legislation, if the service brake system (except the parking one) or steering system malfunctions, movement and further operation of the vehicle is completely prohibited. This is the only situation where the car cannot even be towed in the usual way, let alone driven independently.
Brake and steering system
Brake failure or loss of steering control are scenarios that should not be tolerated under any circumstances. The legislation clearly classifies faults, focusing on the working and parking systems. If you notice that the car pulls to the side when braking, or the pedal fails, further movement should be stopped immediately.
If problems are detected with steering, such as play above acceptable standards or jamming of the mechanism, operation becomes impossible. Even a seemingly insignificant leak of brake fluid from a hydraulic drive is grounds for prohibiting operation. Don’t try to get to the service “on the leftovers”, it could cost your life.
- 🛑 The tightness of the hydraulic brake drive is broken.
- 🛑 The parking brake system does not work (on steep inclines).
- 🛑 The steering play exceeds the established standards.
- 🛑 The steering shaft is missing or not fixed.
⚠️ Attention: If only the parking brake system is faulty, movement is allowed to the parking or repair site, but with extreme caution. However, if the working system fails, the machine becomes an unguided projectile.
Check the brake fluid level in the reservoir before every long trip. A sharp drop in level often indicates a leak or critical pad wear.
Hitch and external lights
Particular attention is paid to towing devices, especially if you plan to tow a trailer. Any design changes not provided for by the manufacturer, or the presence of play in the connection, can lead to the trailer being torn off while moving. Checking this unit should be part of a mandatory ritual before starting movement.
Lighting devices make your vehicle visible to other road users. Missing or not working headlights and rear marker lights make operation impossible at night or in poor visibility conditions. Self-made light signals or changing the color of standard lamps are also strictly prohibited.
There are situations when driving with faulty headlights is only allowed to a parking lot or repair site, but only during daylight hours. However, the lack high and low beam headlights on motorcycles is an absolute ban on driving at any time. Don't risk relying on "daytime running lights" if the main headlights are broken.
Windshield wipers and glasses
Driver visibility is a critical safety parameter. If your windshield wipers stop working during rain or snow, continuing to drive in traffic becomes deadly. The rules strictly regulate the condition of the glass and the efficiency of the windshield wipers.
Operation is prohibited if those specified in the design do not work. windshield wipers. This applies not only to the windshield, but also to the rear one, if it is a mandatory element of visibility for a given car model. Ignoring this rule in bad weather is tantamount to driving with your eyes closed.
- 🌧️ Windshield wipers do not work in rain or snowfall.
- 💥 There are cracks on the windshield in the wiper area on the driver's side.
- 🎨 Objects or coatings are applied to the glass that limit the view from the front.
- 🚫 There are no side windows provided for by the design.
Separately, it is worth mentioning the tinting. Although not a mechanical failure, the application of coatings that restrict visibility is considered a technical violation prohibiting operation. Make sure that the light transmission of the glass complies with the standards to avoid problems with inspectors.
Not working wipers in the rain is not just a fine, it is a direct threat to life. Stop and repair the problem or wait until the weather improves.
Wheels and tires: critical parameters
The condition of your wheels and tires directly affects traction and handling. A worn tread is unable to effectively drain water, which leads to aquaplaning. There is a minimum tread height below which tire use is prohibited by law.
For passenger cars, the residual tread depth must be at least 1.6 mm. For trucks this parameter is higher - 1 mm, and for motorcycles - 0.8 mm. In addition, the presence hernias, breaks exposing the cord, or the absence of at least one wheel bolt is grounds for immediate prohibition of operation.
| Vehicle type | Minimum tread height | Acceptable damage |
|---|---|---|
| Passenger cars (category B) | 1.6 mm | No hernias or cord breaks |
| Trucks (category C) | 1.0 mm | No delaminations |
| Motorcycles and mopeds | 0.8 mm | No through holes |
| Buses | 2.0 mm | Strictly no defects |
It is also prohibited to install tires with different tread patterns or different degrees of wear on one axle. This may cause the vehicle to skid when braking. Studded tires must be installed on all wheels of the vehicle at the same time, if required by the design or seasonal conditions.
Engine and exhaust system
The technical condition of the engine affects not only dynamics, but also environmental safety. It is prohibited to operate vehicles if the content of harmful substances in the exhaust gases exceeds the standards established for this model. This often applies to cars with a faulty catalytic system or incorrect fuel system settings.
A fuel leak from the tank or power system is a fire hazard in which further movement is strictly prohibited. Even small drops of gasoline or diesel fuel under the car should be a signal to immediately stop and call a tow truck.
⚠️ Attention: A malfunction of the exhaust system, resulting in excessive noise or smoke levels, is also grounds for prohibiting operation. A loud exhaust is not a sign of power, but a violation of the law.
What happens if you continue driving with a fuel leak?
In addition to the high risk of fire, fuel vapors can enter the cabin, causing poisoning of the driver and passengers with carbon monoxide or gasoline vapors.
Rules for towing in case of malfunctions
If your car breaks down, it's important to understand whether it can be towed. As mentioned earlier, normal towing is prohibited if the brake system or steering system is faulty. In such cases, only full loading onto a tow truck is required.
Other types of faults have their own rules. The hitch should be rigid or flexible, depending on the type of failure. If they don't work brakes (but the steering is working properly), only a rigid coupling is possible. If the steering does not work (but the brakes work), partial towing is also allowed.
- 🔗 A rigid coupling is required if the brakes of the towed vehicle are faulty.
- 🚗 Partial loading is necessary when the steering is not working.
- 🚫 A complete ban on towing when the lighting is not working at night.
☑️ Check before towing
Frequently asked questions (FAQ)
Is it possible to drive to the repair site with a broken headlight?
Yes, the rules allow movement to a parking or repair site, but only during daylight hours and subject to safety precautions. At night, driving with non-functioning headlights is strictly prohibited.
What is the penalty for operating a car with faulty brakes?
According to Part 2 of Article 12.5 of the Code of Administrative Offenses of the Russian Federation, driving a car with a faulty brake system (except for parking) entails a fine of 500 rubles. However, the inspector also has the right to prohibit further operation and send the car to the impound lot.
Is the absence of a first aid kit a malfunction that prohibits movement?
No, the absence of a first aid kit, fire extinguisher or warning triangle is not included in the list of faults for which it is prohibited exploitation vehicle.
