Traffic regulations: list of malfunctions and conditions for prohibiting operation

Every driver is required to know the rules of the road, but the key document that determines the technical safety of your car is the “List of faults and conditions under which the operation of vehicles is prohibited.” This document is an integral part of the traffic rules and serves as the main guide for traffic police inspectors when conducting road inspections. Ignoring these rules not only creates the risk of receiving a fine, but also directly threatens the lives of all road users.

The driver is obliged to visually assess the technical condition of his car before each trip. Prohibition of operation occurs not only in the event of a complete breakdown of the units, but also in the presence of even seemingly insignificant defects that can lead to an accident. It is important to understand that responsibility for the serviceability of the car lies solely with the owner, and citing ignorance of technical regulations will not be an excuse in the event of an accident or stop by police officers.

In this article we will examine in detail the main sections relating to the braking system, steering, external lighting devices and other critical components. You will learn in which cases you can continue driving only to a parking or repair site, and when the car must be towed immediately. Accurate knowledge of these rules will help you avoid conflict situations with the law and protect yourself on the road.

Brake system: safety criteria

The braking system is one of the most important elements of active safety, and the requirements for it in the traffic rules are formulated as strictly as possible. Operation of the vehicle is strictly prohibited if the seal of the hydraulic brake drive is broken. Even a minimal leak of brake fluid can lead to complete system failure at the most inopportune moment, which is fraught with serious consequences.

Also movement is prohibited when braking efficiency decreases or the vehicle pulls to the side when braking. This may indicate uneven pad wear, stuck calipers, or problems with braking force distribution. The inspector can identify these malfunctions during instrumental inspection or even visually based on braking marks.

⚠️ Attention: If while driving you feel a failure of the brake pedal or an increase in the braking distance, further operation of the car is life-threatening. You must stop immediately and call a tow truck.

Particular attention should be paid to the parking brake. If hand brake does not hold the car on slopes determined by technical regulations, operation is also prohibited. This is critical for parking on terrain where spontaneous movement of the car can lead to a collision with other objects.

Steering: Trajectory Control

Steering provides the ability to maneuver and maintain a given trajectory. According to the list of faults, movement is prohibited if there is steering play in excess of the permissible values. For passenger cars this figure is no more than 10 degrees. Exceeding this parameter makes the steering wheel “empty” and does not allow you to quickly respond to changes in the road situation.

In addition, operation prohibited if there are visible violations of the fastening of the steering column, universal joint or steering rod bipod. Any cracks or deformations of these elements can lead to complete destruction of the unit and loss of vehicle control at high speed. The driver is responsible for regularly visually inspecting these components, especially after driving on poor roads.

Power steering problems can also cause you to become immobilized if they cause the steering wheel to jam or force you to turn suddenly. Hydraulic or electric drive should operate without jerking or extraneous noise, ensuring smooth control.

Exterior lights and windshield wipers

Lighting devices ensure visibility of the vehicle on the road and illumination of the path at night. Traffic regulations strictly regulate their work: movement is prohibited unless the high and low beam headlights, tail lights or brake lights are on. The absence of even one of these elements makes the car “invisible” to other road users in certain conditions.

Also operation is prohibited when the turn signals are off, since they are the main means of communication between drivers. Malfunction of the alarm system or retroreflective devices (reflectors) is also grounds for a traffic ban. It is important to ensure the cleanliness and integrity of the lenses, as cracks can lead to moisture ingress and failure of the lamp.

Windshield wipers and windshield washers deserve special attention. If the windshield wipers do not work during rain or snow, the driver's visibility is sharply reduced, which makes driving dangerous. In such conditions vehicle operation prohibited until the malfunction is eliminated.

• 🚗 Malfunction of low beam headlights at night
• 🛑 No working brake light
• 💧 Windshield wiper failure during precipitation
• 🔦 Turn signals not working

Wheels and tires: condition requirements

Wheels and tires are the vehicle's only point of contact with the road, and their condition directly affects traction and stability. Driving is prohibited if the remaining tire tread depth is less than 1.6 mm for passenger cars. For winter tires this threshold may be higher, and the use of summer tires in winter is also a violation of the rules.

Operation prohibited if there is damage to the tires, such as through punctures, ruptures, carcass delamination or tread peeling. Also, avoid using tires that show visible signs of uneven wear, which could indicate suspension or wheel alignment problems. The absence of at least one wheel bolt or visible cracks on the rims is a direct path to an accident.

Particular attention should be paid to the installation of tires. Tires with the same tread pattern must be installed on one vehicle axle. The combination of studded and non-studded tires, as well as the use of bias and radial tires at the same time, is strictly prohibited by the rules.

How to check tire wear without a ruler?

Use a 1 ruble coin. Insert it into the tread groove with Lenin's head down. If the entire head to shoulders is visible, the protector is worn out and requires replacement. If only the forelock is visible, the rubber is still suitable for use.

Engine and exhaust systems

Although the engine is a powertrain, engine failure can create dangerous situations on the road. Driving is prohibited if the content of harmful substances in the exhaust gases exceeds the standards established by the technical regulations. This is not only an environmental issue, but also a safety issue: improper operation of the engine can lead to a fire or loss of traction at a critical moment.

Also operation is prohibited when there is a fuel leak from the tank or power system pipelines. Gasoline or diesel fuel vapors are highly flammable, creating a fire hazard. The presence of a fuel smell in the cabin or under the hood is a signal that an immediate stop and diagnostics are required.

Exhaust system malfunctions, such as loud noises or sparks, are also grounds for a driving ban. Muffler must provide the required noise level and safe removal of gases. Damage to the exhaust system can lead to carbon monoxide entering the cabin, which is fatal for the driver and passengers.

Malfunction	Risk	Action
Fuel leak	Fire, explosion	Stop, evacuation
Exceeding toxicity	Pollution, fine	Engine repair
Noisy exhaust	Discomfort, fine	Muffler replacement
Emission of sparks	Cargo ignition	Exhaust system repair

Other elements and conditions of the traffic ban

In addition to the basic systems, there are a number of other conditions under which the vehicle cannot be operated. These include malfunctions of the towbar if the vehicle is being used with a trailer. Any looseness in the connections or cracks in the detailing can cause the trailer to become detached while moving.

Driving is prohibited if the rear view mirror or driver's seat provided by the design are missing or the truck's side locking device is faulty. Driver safety and the cargo must be secured completely. Also, you cannot operate a car if the state registration plates are missing or unreadable.

An important aspect is the presence of a first aid kit, a fire extinguisher and a warning triangle. Although their absence does not technically affect driving performance, operating the vehicle without them is prohibited by the rules. These items are necessary for providing first aid and marking the scene of an accident.

Liability and penalties for defects

Violation of the rules for operating vehicles entails administrative liability. According to the Code of Administrative Offenses, driving a car with defects that prohibit operation is subject to a warning or a fine. The amount of the fine depends on the type of fault and the degree of danger it poses.

The most severe penalties apply for faults in the braking, steering and clutch systems. In such cases, the inspector has the right to prohibit further movement and send the car to the impound lot until the problem is eliminated. Repeated violation may lead to an increase in the fine.

⚠️ Attention: A fine for a malfunction is not the worst consequence. The main danger is the high risk of an accident, for which liability may already be criminal.

It is worth noting that some faults allow you to continue driving only to the place of parking or repair, observing safety precautions. However, this does not relieve the driver of responsibility for driving a technically faulty vehicle. It is better to spend time fixing the breakdown in advance than to risk your life and wallet.

Frequently asked questions (FAQ)

Is it possible to drive to the repair site if the Check Engine light is on?

Illumination of the Check Engine lamp in itself is not a direct basis for prohibiting operation according to the List if the engine is running smoothly and there are no leaks. However, this is a signal of a malfunction that needs to be diagnosed. If the car behaves adequately, you can get to the service station.

What is the penalty for not having a windshield wiper on one side?

If windshield wipers do not work or are missing, which reduces visibility in bad weather, this falls under item 4.2 of the List. The fine is 500 rubles (part 1 of article 12.5 of the Code of Administrative Offenses of the Russian Federation). In rain or snow, driving with such a malfunction is completely prohibited.

Is driving allowed if one rear view mirror is broken?

No, according to the List of Faults (clause 7.3), the absence of at least one of the rear-view mirrors provided for by the design prohibits operation. This is a critical element for monitoring the situation behind the vehicle.

What to do if a malfunction is discovered on the way?

If the malfunction is classified as prohibiting movement (brakes, steering, lights), you must stop in a safe place, turn on the hazard lights and put up a warning triangle. Next, you should call a tow truck or, if the rules allow (for example, if the light fails during the day), move with precautions to the repair site.
