Malfunctions for which the operation of vehicles is prohibited: a complete list and consequences

Operating a vehicle with defects is not only a safety risk, but also a direct violation of current legislation. According to Resolution of the Government of the Russian Federation No. 1090 (last edition 2026), there are critical breakdowns in which driving a vehicle (VV) is strictly prohibited. Traffic police inspectors have the right not only to issue a fine, but also suspend the vehicle until the defects are eliminated - even if you are going to a service station.

In this article we will look at full current list of faults, in which the operation of vehicles is prohibited, we will explain why they are considered dangerous, and we will tell you how to avoid problems with the law. We will pay special attention to the “gray areas” - situations where the inspector can interpret the rules in his favor, and will provide a checklist for independently checking the car before the trip. If you are planning to buy a used car or are preparing for an inspection, this information will help save time and money.

1. Brake system: when the car is sent to the tow truck

Brake malfunctions are the most common reason for prohibiting operation. According to traffic police statistics, more than 30% of road accidents with serious consequences occur due to a failure of the brake system. In this case, the inspector will not check the effectiveness of braking by eye - visual signs or data from diagnostic equipment are sufficient.

Critical faults:

• 🚨 Brake fluid leak - even a small puddle under the car or a drop in the level in the tank below the mark MIN.
• 🛑 Parking brake not working - if the car cannot be maintained on a slope of 23% (standard for passenger vehicles).
• ⚠️ Different pedal efforts when pressed - indicates a malfunction of the brake master cylinder or circuits.
• 🔧 Cracked or corroded brake hoses - visually noticeable defects, even without leakage.

Special attention - electronic help systems (ABS, ESP). If the indicator on the dashboard is on ABS or ESP OFF, this is not always a ban on operation, but an inspector may require you to check the performance of the systems at a service station. For example, on Volkswagen Golf or Skoda Octavia with electronic handbrake system failure EPB is equivalent to a non-working parking brake.

⚠️ Attention: If you have a hydraulic brake system, check the fluid level every 10,000 km. In cars with electronic brake drive (for example, Tesla Model 3) diagnostics must be carried out through the service menu or scanner.

2. Steering: when “play” becomes a criminal matter

Steering problems are the second most dangerous group of faults. Here, traffic police inspectors are especially strict: even minimal play or tight rotation of the steering wheel can lead to a ban on operation. The main standard is total play no more than 10° (for passenger cars).

What they check:

• 🔄 Steering wheel play — if the wheels do not react immediately when you rock the steering wheel.
• 🛢️ Power steering/electric power steering fluid leak — oil stains under the steering rack or pump.
• 🔊 Knocks or squeaks when turning the steering wheel, especially at Korean cars (Hyundai Solaris, Kia Rio).
• 🚗 Wheel misalignment - if, when driving straight, the steering wheel “leads” to the side.

On vehicles with electric power steering (for example, Renault Duster or Lada Vesta) the inspector may require you to check errors through the diagnostic connector. Code C1010 (rotation angle sensor malfunction) - direct prohibition of operation.

Malfunction	Consequences	Fine (2026)
Steering play >10°	Prohibition of operation, evacuation	500–1 000 ₽
Power steering fluid leak	Ban until eliminated	500 ₽
Inoperative EUR	Prohibited if the steering wheel is locked	1 000 ₽

3. Exterior Lights: When a Flashing Light Becomes a Problem

Lighting faults are one of the most common causes of fines. According to GOST R 51709-2001, even one unlit lamp can become grounds for prohibiting operation. At the same time, inspectors often “forget” that some requirements depend on the time of day.

What is prohibited:

• 💡 No lights or lights — at least one lamp in a pair (for example, the left low beam headlight).
• 🔦 Incorrect light adjustment - if the headlights shine “into the sky” or blind oncoming drivers.
• 🚨 Absent or faulty brake lights - even if at least one of the two is on.
• 🔄 Turn signals not working — if only one flashes (for example, the right front).

Features for different types of lamps:

• Halogen - check the temperature color (not higher than 4300K).
• Xenon - presence is required headlight washers and autocorrector.
• LED lamps - must be certified for this model (for example, Osram LEDriving for Toyota Camry).

⚠️ Attention: If you have installed non-standard LED lamps (for example, in PTF), the inspector has the right to prohibit operation, even if they are on fire. Demand to show certificate of conformity for your car model.

4. Wheels and tires: when “bald” tires threaten not only with a fine

The condition of tires and wheels is not only a matter of fines, but also your safety. According to Technical Regulations of the Customs Union 018/2011, operation is prohibited when:

• 🚗 Remaining tread depth less than 1.6 mm (for summer tires) or 4 mm (for winter).
• 🔧 Different tires on one axle - even if they are the same model, but with different degrees of wear.
• 💥 Visible damage: hernias, cuts, exposed cord.
• 🔄 Seasonality inconsistencies — winter tires in summer (from June 1 to August 31) and vice versa.

Special attention - studded tires. If there are less than 60% thorns from the original amount, this is equivalent to “bald” tires. For example, on Nokian Hakkapeliitta 9 initially 190 studs - if less than 114 remain, operation is prohibited.

Also check:

• Tire production date - if the tire is more than 5 years old (even with good tread), the inspector may issue a warning.
• Tire pressure - if it is visually noticeable that the tire is “flat” (for example, 1.8 atm instead of the required 2.2 atm).

Parameter	Summer tires	Winter tires
Minimum Tread	1.6 mm	4 mm
Max. age (recommendation)	5 years	4 years
Penalty for violation	500 ₽	500–1 000 ₽

What happens if you drive on bald tires?

In addition to a fine, the insurance company may refuse to pay in case of an accident, citing violation of operating conditions (clause 2.3.1 of the traffic rules).

5. Engine and exhaust: when a “smoking” car becomes a threat

Malfunctions of the engine and exhaust system not only harm the environment, but can also lead to termination of vehicle registration. According to GOST R 52033-2003, prohibited:

• 💨 Excess smoke - for diesel engines the norm 1.5 m⁻¹ (when checked at a service station).
• 🔊 Faulty muffler - if you hear popping or “shooting”.
• 🛢️ Fuel or oil leak - even drops under the car.
• 🚗 Not working catalyst - if removed or clogged (check with a scanner for errors P0420).

Features for different engine types:

• Gasoline - check the content CO (norm up to 0.3%) and CH (up to 100 ppm).
• Diesel - measure smokiness at free acceleration (norm up to 0.7 m⁻¹ for cars older than 2014).
• Hybrids/electric vehicles - check only visually (no exhaust, but there may be coolant leaks).

For example, on BMW 5 Series (F10) with diesel engine N57 A common problem is a clogged particulate filter (DPF). If the error is on P242F, operation is prohibited until cleaned or replaced.

⚠️ Attention: If your catalyst has been removed and a fake one has been installed in its place, the inspector has the right rent rooms until the ecological class is restored. This also applies to “flashed” cars with disabled EGR.

6. Windshield wipers, mirrors and glass: little things that will result in a fine

It would seem that what is dangerous about a non-working wiper? However, according to clause 4.1 List of faults, even such “little things” can cause a ban on operation. What they check:

• 💧 Windshield wipers not working - if at least 70% of the windshield is not cleaned.
• 🪞 Lack of mirrors - at least one of the two (left or right).
• 🚗 Cracks in the windshield - if they are in the area where the wipers are working or distort the view.
• 🔦 Tinting is higher than normal — the light transmission of the front windows is less 70%.

Features:

• On commercial vehicles (for example, Gazelle Next) are required side mirrors on both sides.
• If you have panoramic windshield (for example, on Nissan Juke), a crack longer than 10 cm - prohibition of exploitation.
• Rear wiper and heated glass not required, if they are not provided for by the design.

Inspectors often get hung up on tint. If you have a film with light transmission 75%, but visually the glass seems darker, may require instrumental check using a taumeter.

7. Body and license plates: when rust becomes a problem

The condition of the body and license plates is not only aesthetics, but also a legal requirement. According to clause 7.18 of the traffic rules, operation is prohibited when:

• 🚗 Body damagethreatening safety (for example, rusty thresholds that may fall off).
• 🔢 Unreadable license plates - if at least one number or letter is illegible.
• 🔧 Lack of bumpers - if they are provided for by the design.
• 🎨 Non-standard coloring — if the color differs from that indicated in the PTS (for example, it was repainted from black to red).

Frequent pitfalls:

• If on the number paint chipped, but the characters are readable - this is not a violation.
• If the bumper cracked but holds up - there is no prohibition if it does not hang on a wire.
• On SUVs (for example, UAZ Patriot) are allowed reinforced bumpers, if they are certified.

Special attention - VIN code. If it is damaged or unreadable (for example, due to corrosion), the inspector has the right detain the car to check for theft.

8. Other faults: what else will be checked on the road

In addition to the main systems, inspectors may prohibit operation for “secondary” but no less important reasons:

• 🚪 Faulty doors - if they do not open from the inside or outside.
• 🔑 Seat belts not working - even if they are fastened, they are not fixed during a jerk.
• 🔋 Low battery - if the car does not start without “lighting up”.
• 📟 Not working horn - if it doesn’t make a sound or is too quiet.
• 🚨 Lack of first aid kit, fire extinguisher or warning triangle — a fine of 500 ₽, but there is no prohibition on operation.

For example, on Lada Granta common problem - broken hood cable. If the hood does not open from the passenger compartment, this is equated to a malfunction of the lock and is grounds for prohibiting operation.

The inspector may also pay attention to:

• Non-standard dimensions - if the car is too wide or high (for example, after a suspension lift).
• No headrests - if they are provided for by the design of the seats.
• Faulty speedometer - if it does not show the speed or shows incorrect data.

FAQ: Frequently asked questions about malfunctions and prohibited operation

Can an inspector prohibit operation if my windshield is cracked but my view is not blocked?

Yes, if the crack is located in the area of cleaning with a windshield wiper (clause 4.3 of the List of faults). Even if it does not interfere with the view, but falls into this area, the inspector has the right to issue a ban. The exception is cracks less than 10 cm, without distorting the view.

What should you do if the inspector asks you to replace a lamp that is lit but dimly?

According to GOST, the lamp must shine with an intensity of at least 70% from nominal. If the inspector states that the lamp is “not compliant,” ask him to measure the lumen output with a lux meter. Without the device, his claims can be challenged.

Can operation be prohibited due to rust on the thresholds?

Yes, if there is rust end-to-end or thresholds deformed so that they threaten safety (for example, they can fall off when moving). If the rust is superficial, this is a remark, but not a ban.

What faults can be corrected on the spot to avoid a fine?

Some problems can be fixed immediately:

• Replace the burnt out lamp (if you have a spare).
• Inflate the flat tire (if there is a compressor).
• Clean the license plate from any dirt.
• Fix the coolant leak (if possible, top up).

But problems such as loose steering or faulty brakes cannot be repaired on the side of the road; a tow truck will be required.

What happens if I ignore the driving ban and continue driving?

If the inspector issued ban on exploitation (there will be a note in the protocol) and you continue to drive, this qualifies as driving a vehicle with obviously faulty systems (Part 2 of Article 12.5 of the Administrative Code). Fine - 5 000 ₽ or deprivation of rights for 1–3 months. In case of repeated violation - deprivation of up to 1 year.
