Every driver must know in what cases his car is technically not allowed to appear on public roads. Ignoring basic safety requirements turns the car into an uncontrollable danger for others and the owner himself. The legislation clearly regulates the condition of components and assemblies that provide control over the vehicle.
There is an approved List of faults, the presence of at least one of which makes further movement impossible. Unlike other breakdowns that can be fixed on the road or reached the repair site, these defects require immediate intervention. The police officer has the right to prohibit further movement and issue a fine if he detects critical violations.
Understanding these rules helps to avoid not only financial losses, but also tragic consequences on the road. Below we will analyze in detail the main car systems, defects of which are strictly unacceptable during operation. Traffic rules of the Russian Federation do not tolerate compromises in matters relating to brakes, steering and lighting.
Brake System: Safety Critical Requirements
Brake performance is the foundation of safe driving. If service brake system does not provide the required deceleration, the car turns into an uncontrollable mass. The effectiveness of braking is checked on special stands, but there are signs that are immediately noticeable to the driver.
One of the main problems is the violation of the tightness of the hydraulic drive. A brake fluid leak causes the pedal to sink in and become completely ineffective. It is also unacceptable if brake pedal does not lock in the pressed position or has excessive free play that does not comply with the technical documentation of the manufacturer.
⚠️ Attention: If while driving you notice a burning smell, squeaking or creaking, accompanied by a decrease in braking efficiency, stop driving immediately. Continued use may result in fire or system failure.
Special attention should be paid to the parking brake. It must hold the car on the slopes provided for by the design. If the handbrake does not work, driving in mountainous areas or parking on slopes becomes deadly.
Check the brake fluid level in the reservoir before each long-haul flight. A sharp drop in level almost always indicates depressurization of the system.
Steering and suspension
The steering mechanism provides control over the trajectory of movement. Any malfunctions here are unacceptable. First of all, this concerns steering wheel play. If the total play exceeds the established standards (usually 10 degrees for passenger cars), control becomes unclear and dangerous.
The list of prohibited faults includes:
- 🔧 Presence of backlashes in rod connections and steering joints.
- 🔧 Malfunction or absence of power steering, if it is provided for by the design.
- 🔧 Spontaneous turning of the steering wheel when your hands are released on a flat road.
Suspension also plays a key role. Fracture or deformation wishbones, as well as loss of elasticity of springs or springs can lead to a change in track and loss of stability. Particularly dangerous are faults that affect wheel alignment in motion.
For a deeper understanding of how different elements affect controllability, consider their influence in the table:
| System element | Fault type | Impact on management |
|---|---|---|
| Steering rods | Wear of hinges | Knocks appear, car pulls away |
| Suspension springs | Breakage of turns | Body distortion, geometry change |
| Shock absorbers | Liquid leakage | Body rocking, increasing braking distance |
| Ball joints | Boot destruction, wear | Knock, risk of wheel coming off |
External lighting and electrical equipment
Lighting devices are the language of communication between drivers on the road. Their malfunction sharply increases the risk of an accident, especially at night or in poor visibility conditions. Operation prohibited, if the high and low beam headlights, as well as the rear side lights, do not light up.
A special requirement is placed on the cleanliness and integrity of the diffusers. If the headlight is dirty or broken so much that the light beam is not distributed correctly, this is considered a malfunction. Also, you cannot use homemade light sources or lamps that do not correspond to the type of base and power provided by the factory.
The list of critical lighting equipment malfunctions includes:
- 💡 Absence or non-lighting of brake lights (braking lights).
- 💡 Malfunction of direction indicators on any side.
- 💡 Absence or non-lighting of reverse lights (for driving at night).
Electrical equipment must be in good working order. The presence of abnormal sources of energy consumption, which can lead to network overload and fire, is prohibited. Wiring must be securely fastened and insulated.
If even one brake light malfunctions, you will not be able to safely brake in front of the next car, since the driver behind you will not see your maneuver.
Windshield wipers, washers and glasses
Visibility is the key to safety. If windshield has damage in the wiper area on the driver's side, operation is prohibited. Cracks, chips or dullness in this area distort the perception of the road situation.
Windshield wipers and washers must work properly. In rain or snow, the absence of windshield wipers makes movement impossible. The mechanism must ensure glass cleaning within the limits necessary for viewing. It is prohibited to use homemade cleaning compounds that erode the glass coating or form a film.
⚠️ Attention: Window tinting is also regulated by the rules. If the light transmission of the windshield or front door glass is below 70%, or if the tinting is applied incorrectly (for example, a mirror film), this is grounds for prohibiting operation.
Rear view mirrors must be intact and securely fastened. The absence of at least one of the mirrors (left or right) and the absence of a central mirror makes reversing maneuvers or changing lanes extremely dangerous.
Wheels and tires
The condition of your tires directly affects your road grip. Remaining tread height is a key parameter. For passenger cars it should not be less than 1.6 mm. For motorcycles, trucks and buses the standards are higher.
In addition to wear, there are other defects for which movement is prohibited:
- 🛞 Presence of through or local damage exposing the cord.
- 🛞 Detachment of the tread or sidewall.
- 🛞 Absence of fastening bolts (nuts) or presence of cracks on the disks.
It is also prohibited to install tires with different tread patterns, dimensions or designs (tube/tubeless, radial/diagonal) on the same axle. This leads to uneven braking and the vehicle pulling to the side.
Seasonal restrictions
In winter (December, January, February), the operation of vehicles without winter tires (marked M+S, M&S, M S) on all wheels is prohibited. Summer tires cannot be used during this period.
Engine, exhaust system, etc.
The technical condition of the engine affects not only the dynamics, but also the environment. It is prohibited to contain harmful substances in the exhaust gases above the standards established for this model. Smoky exhaust is a sign of a malfunction in the power system or cylinder-piston group.
The exhaust system must be sealed. The presence of holes in the muffler or exhaust pipe, as well as loud noise exceeding the established standards, are grounds for prohibiting operation. Exhaust system should not allow gases to enter the vehicle interior.
Malfunctions also include:
- ⛽ Malfunction of the power supply system (fuel leakage).
- ⛽ Cooling system leaks.
- ⛽ Lack of hood locking device.
☑️ Express check before departure
Frequently asked questions (FAQ)
Is it possible to drive to the repair site if one brake light is faulty?
No, according to traffic regulations, malfunction of external lighting devices (except for reflectors) is included in the list of malfunctions for which operation is prohibited. However, in practice, if you turn on your hazard lights and drive with extreme caution to the nearest parking or repair site, the risk of being stopped is reduced, but technically driving is prohibited.
What to do if a malfunction is discovered on the way?
If the malfunction is included in the list for which operation is prohibited (for example, the brakes or steering have failed), you must stop driving. If possible and safe, try to fix the problem on site. If not, call a tow truck. Driving under your own power with such defects is prohibited.
Is there a fine for driving with a faulty windshield wiper?
Yes, for driving a vehicle with malfunctions for which operation is prohibited, liability is provided under Part 2 of Art. 12.5 Code of Administrative Offenses of the Russian Federation. This entails a fine of 500 rubles. However, the inspector also has the right to prohibit further movement until the cause is eliminated.
Is the lack of a first aid kit and fire extinguisher grounds for prohibiting use?
No, the absence of a first aid kit, fire extinguisher and warning triangle is not included in the “List of faults” for which the operation of the vehicle is prohibited. For this, a separate fine is provided under Part 1 of Art. 12.5 of the Code of Administrative Offenses of the Russian Federation (500 rubles or a warning), but they cannot ban traffic or send you to the impound lot for this.
