Braking with uneven tire wear between the left and right sides is dangerous because it can cause the vehicle to slide off the road and overturn.

If the windows fog up (for example after washing the vehicle), the heating/ventilation setting may be incorrect.

RTR 151. If a vehicle is forced to stop where standing or parking is prohibited, the driver must switch on the hazard warning lights if available and/or place a warning triangle on the road as specified in Paragraph 92 of the Rules, and remove the vehicle from the road as soon as possible. If the driver intends to stop on unlit sections of road during the hours of darkness or when visibility is poor, and the hazard warning lights are not available or are inoperative, the vehicle must be parked off the carriageway. If that is impossible, the stopping location must be marked as specified in Paragraph 92 of the Rules. RTR 92. If the emergency light signalling system is not fitted or is defective and an emergency stop is required where stopping or parking is prohibited, in the event of an accident, or where the stopped vehicle would be visible to other road users from less than 100 metres, the driver of a motor vehicle (other than a motor moped or a motorcycle without a trailer), a tractor or a self-propelled machine must immediately erect an emergency stop sign on the side of the carriageway opposite the direction of travel: in built-up areas not closer than 25 m, and outside built-up areas not closer than 50 m to the stopped vehicle. If at least one rear position lamp is defective and the emergency light signal does not work when driving in the dark or in poor visibility, an emergency stop sign must be affixed to the rear of the vehicle in order to continue driving. Law on Road Traffic Safety art. 13.14. The driver of a motor vehicle, tractor or self-propelled machine who stops at night on an unlit road or in conditions of poor visibility, except in designated parking spaces, must wear a high-visibility vest with reflective elements. JB

RTR XI. WARNING SIGNALS (paras. 81–93). Paragraph 87: A driver who issues a warning signal does not have the right of way.

When you see a pothole, reduce your speed and try to steer around it. If avoidance is impossible and an impact cannot be prevented, release the brakes just before the pothole and straighten the steering — this reduces the chance of damaging the tire or suspension components.

RTR XVI.140. Overtaking is forbidden: 140.1. at intersections, except where overtaking on a main road is permitted because the intersection is not marked by one of the following signs: 'Intersection with the Side Road', 'Side Road on the Right', 'Side Road on the Left', or 'Priority Road'; 140.2. at level crossings and within 100 m of a level crossing; 140.3. on road sections with poor visibility; 140.4. on pedestrian crossings; 140.5. on roads with more than one lane in the same direction; 140.6. on road sections marked with the signs 'Overtaking is prohibited' or 'Overtaking by trucks is prohibited' (see the explanations for these signs); 140.7. on road sections where opposing traffic flows are separated by longitudinal markings 1.1, 1.3, 1.4, 1.10 (from the continuous line side) and 1.15 listed in Appendix 3 of the Rules; 140.8. in residential areas, apartment building courtyards, parking lots and bicycle streets. JB

629. 'Place of Interest' sign. Indicates the name of a cultural or historical site of interest. The sign has a brown background.

The correct action is to apply the brakes and release the accelerator pedal, because you must be prepared to stop if necessary. Road sign 203 — "Give Way" — indicates that drivers must yield to vehicles travelling on the road being crossed. If supplementary panel No. 843 "Direction of Priority Road" is mounted beneath the sign, you must yield to vehicles on the priority road.

According to the traffic regulations, vehicles fitted with studded tyres must not be used from April 10 to October 31. Therefore, winter tyres without studs are permitted during that period. However, using summer tyres is recommended in warm conditions. If winter conditions persist, the Minister of Transport and Communications may issue an order extending the permitted use of studded tyres.

Even if another driver breaks the rules by overtaking or exceeding the speed limit, you must not endanger other road users — allow that driver to overtake you. 4. Road users shall follow the principle of mutual respect and safety.

Open windows and sunroofs reduce the car's aerodynamic properties - it starts to move more slowly, more energy is needed to maintain speed, so fuel is used less efficiently, more is needed. JB

RTR 136. Drivers should avoid unnecessary overtaking manoeuvres. Before overtaking, drivers must exercise extra caution and ensure that: 136.1 no driver following has already begun to overtake them; 136.2 the driver of the vehicle to be overtaken is not indicating a left turn; 136.3 the section of lane required for the overtaking manoeuvre is clear and the manoeuvre will not obstruct oncoming traffic or pedestrians on the carriageway; 136.4 a safe distance from the vehicle being overtaken can be maintained during the manoeuvre; 136.5 after completing the overtaking manoeuvre they will be able to return safely to the original traffic lane without obstructing the overtaken vehicle.

RTR 73.11. A red light or two alternately flashing red lights prohibit traffic; if the light displays black arrow(s), it prohibits traffic in the direction(s) indicated by the arrow(s) and indicates which directions road users may proceed when the green arrow appears. RTR 162. Drivers who entered the intersection in accordance with a traffic light signal permitting them to proceed may continue in their intended direction regardless of the traffic light signal shown when the vehicle is leaving the intersection. However, if the 'STOP' sign and/or a 'Stop' line is present at the intersection before other traffic lights on the route, the driver must obey every traffic light signal. RTR 165. If traffic light signals or traffic officers prohibit driving, drivers must stop before the 'STOP' sign and/or the 'Stop' line if present; if not, they must stop before the traffic lights, before the carriageway they are about to cross or join, or before a pedestrian or bicycle crossing so as not to obstruct vehicular or pedestrian traffic.

High speed is unsafe on icy roads because the slippery surface increases braking distance; therefore you should drive slowly. On slippery roads, also try to prevent excessive wheel slip by keeping engine revolutions low — a higher gear results in lower engine RPM. Select a gear appropriate for your speed, but ensure it is as high as possible. If you feel the vehicle beginning to skid, immediately and gently release the accelerator and do not change the clutch pedal position.

Drivers and all passengers must wear seat belts in vehicles that are equipped with them. In buses fitted with seat belts, a "Fasten Your Seat Belt" notice must be displayed in a clearly visible location in front of each seat, on the seat, or adjacent to it. It is recommended that all bus passengers be informed of the seat belt requirement — either verbally or by audiovisual means — before the journey begins.

As the ambient temperature decreases, the battery capacity of the battery decreases. A fully charged battery has a capacity of 100% at +25 °C, so at 0 °C the battery capacity will drop to 80% and at -25 °C it will be only 60%.

The function of a vehicle suspension system is to convert bumps and shocks transmitted to the wheels, with the aid of shock absorbers, into minor oscillations of the vehicle body, providing comfort for driver and passengers. The suspension reduces body oscillations, and when functioning properly it enhances driving safety.

Regulation RTR 173. Drivers must not: 173.3. enter a level crossing after the barrier has been lowered or is in the process of being lowered; deliberately lift the barrier; or drive around the barriers.

Long journeys can cause the driver to become distracted and fatigued for extended periods, which reduces reaction time and concentration and increases the risk of mistakes. It is recommended to take breaks every 1.5 to 2 hours or after driving approximately 200 kilometres. Sitting for long periods can lead to muscle tension and poor circulation, so getting out of the vehicle helps relax the body and improve well‑being. Exiting the car or opening a window to breathe fresh air can refresh the mind, restore energy and improve concentration.

101. Before starting to move, changing lanes, or otherwise altering course, drivers must ensure the manoeuvre is safe and give way to other road users (i.e., avoid creating obstructions).

77.2. Right arm extended forward: 77.2.1. Vehicles to the officer's left may proceed in any direction; 77.2.2. Vehicles in front of the officer may proceed only to the right; 77.2.3. Vehicles behind the officer and those on his right must not proceed.

When engine oil is low, internal components receive less lubrication, causing increased wear and overheating; this accelerates deterioration and can lead to engine failure.

A catalytic converter neutralises (burns) harmful exhaust gases. It converts three toxic substances—carbon monoxide (CO), nitrogen oxides (NOx), and unburnt hydrocarbons (UHC)—into non-toxic substances through oxidation and reduction reactions. Its purpose is not to dampen engine noise; that is the role of the muffler (silencer). Removing a catalytic converter can alter the car's exhaust sound and often makes it louder or harsher, but this is only a side effect, not the converter's primary function.

Only the driver is allowed not to wear a seat belt in a residential area (e.g. in a parking lot). RTR 196. All passengers and a driver must wear seat belts when travelling in vehicles equipped with them. If a bus is fitted with seat belts, informative signs 'Fasten Your Seat Belt' must be displayed in a visible place in front of every seat, on the seat, or next to it. It is recommended that all passengers in the bus be informed of the requirement to wear seat belts orally or by audio-visual means before starting their journey. RTR 198.  Persons driving a vehicle in reverse or in a parking lot are exempt from wearing seat belts in built- up areas. RTR 205. Persons who due to serious medical reasons hold special permits issued by competent institutions are exempt from wearing seat belts. These permits must have an expiry date. JB

Maintain a speed that allows you to stop the vehicle with the parking brake if necessary. Switch on your hazard warning lights to warn other road users. Drive to the nearest safe place to stop and call roadside assistance.

According to the Road Traffic Rules (RTR), a blue sign showing the settlement name in white letters indicates the start of a settlement where the special traffic regulations that normally apply within built-up areas do NOT apply. By contrast, a sign with the settlement name in black letters on a white background marks the start of a settlement where built-up-area traffic rules are in force (RTR 131). The following maximum speeds apply outside built-up areas (RTR 131.1): for passenger cars, light goods vehicles with a permissible maximum mass up to 3.5 tonnes, motorcycles and tricycles — on motorways: 130 km/h from April to October and 110 km/h from November to March; on expressways/highways: 120 km/h from April to October and 110 km/h from November to March; on roads with asphalt or concrete pavement: 90 km/h; on other roads: 70 km/h. See road sign 612: Beginning of a built-up area where special built-up-area rules do not apply. Road sign 613: End of a built-up area (marked by sign 616); it may show the name of another settlement and the distance to it.

RTR 112. When an acceleration lane is provided for entering a roadway, the driver must use it to gain speed and merge into the main traffic flow, yielding to vehicles already on the road. The driver may change lanes as necessary or enter a deceleration lane when appropriate. JB

RTR 30. When approaching an uncontrolled pedestrian crossing, a driver must slow down or stop before the crossing to yield to pedestrians who have stepped into any lane, are moving within any lane, or are standing immediately before a lane (at the edge of the roadway) waiting for the opportunity to step into that lane in the direction of the vehicle’s travel or into any lane on a road with one lane in each direction. Drivers must take extra precautions during hours of darkness, when visibility is poor, or whenever a pedestrian crossing is not clearly visible from the driver’s position, and must ensure there are no pedestrians who should be given way at the crossing.
