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 Criminal Code of the Republic of Lithuania Article 281.1. When under the influence of alcohol with a blood alcohol content of 1.51 per mille and more, people who drive a motor vehicle, tractor, or self-propelled vehicle or teach a learner driver to drive; or who avoided a field sobriety test when identified with the signs of intoxication; or who had consumed alcohol after a road accident before the circumstances of the road accident were figured out and had been found intoxicated with a blood alcohol content of 1.51 per mille and more shall be punished by a fine or arrest or by imprisonment for a term of up to one year. 

It is prohibited to drive a vehicle if the main brake is inoperative, as this creates a danger to road safety. According to technical requirements, tyres mounted on the same axle must be of the same type and have identical tread patterns. Tyres with different tread patterns can cause instability under braking and reduce traction, creating a road safety risk; therefore driving such a vehicle is prohibited. RTR 234. A driver must not operate a motor vehicle, a tractor, or a self-propelled machine with: 234.1. a defective foot brake (the driver cannot stop the vehicle); 234.2. a defective steering mechanism (the driver cannot control the vehicle); 234.3. a defective coupling device between the vehicle and a trailer; 234.4. a defective windscreen wiper on the driver's side in snow, rain, or fog; 234.5. faulty front left-side lamps (dipped-beam headlamp and fog lamp) during hours of darkness or when visibility is poor, or if at least one rear position lamp has failed, hazard warning lights are not functioning (or are switched off), or a warning triangle is not affixed to the rear of the vehicle.

Passengers may board or alight from the roadway side only when it is impossible to do so from the pavement (sidewalk) or hard shoulder, and only if it can be done safely without obstructing other road users.

Heavy rain forms a layer of water on the asphalt surface (especially where longitudinal ruts are pressed), which is not able to drain so quickly to the side of the road. If we drive fast in such conditions, the tire tread can't squeeze the layer of water formed on the road from under the wheel and the so-called aquaplaning (water wedge) begins. In other words, the car's wheels no longer touch or have a worse grip on the asphalt surface and the car can become out of control. JB

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.

RTR 16. A driver must stop the vehicle when ordered by the inspecting officer. The driver of a motor vehicle, tractor, self-propelled vehicle or military vehicle (including tactical and logistical vehicles and combinations with trailers) must carry and, upon request of the inspecting officer, present a valid driving licence or a document certifying the right to drive tractors and/or self‑propelled vehicles or military equipment; the vehicle registration documents and proof of the compulsory roadworthiness test (including the report of the most recent technical inspection for vehicle categories M2, M3, N2, N3, O3, O4 and wheeled tractor categories T1b, T2b, T3b, T4.1b, T4.2b, T4.3b, T5); the certificate (policy) of compulsory motor third‑party liability insurance; and other documents required by the laws of the Republic of Lithuania and these Rules (except where the Law on Road Traffic Safety exempts the driver from carrying certain documents). The driver must also allow the inspecting officer to check the readings of validated tachographs or other devices that record driving time and rest periods. Documents shall be presented to the inspecting officer without leaving the vehicle. The driver may exit the vehicle only with the inspecting officer’s permission. RTR 91. If the vehicle is equipped with hazard warning lights, they must be switched on: 91.3 when the vehicle is stopped by an inspecting officer. JB

Even at 30 km/h, a collision can seriously endanger the health or life of drivers and passengers. For example, in a head-on collision between two vehicles travelling in opposite directions.

Outside built-up areas, a driver may warn others when overtaking by flashing the high or low beams (provided this does not dazzle other road users) or by sounding the horn. Within built-up areas, flashing the lights is permitted if it does not dazzle others; sounding the horn is prohibited except when necessary to avoid a traffic accident. RTR — 89.

Explanation of terms: • To brake – means pressing the brake pedal; the car quickly slows down and stops before the expected obstacle. • To release the accelerator pedal – means taking your foot off the gas; the car gradually slows down on its own but does not stop completely, it keeps moving. • To drive without changing speed – means pressing the gas pedal the same amount; the car continues moving at a constant speed. RTR 127. Drivers must not exceed the permissible speed limit. A driver must select the driving speed in accordance with the driving conditions, in particular the terrain, the condition of the road and the vehicle including the load, weather conditions, traffic heaviness so that he could safely stop the vehicle before any predictable obstruction. The driver must slow down and stop if the driving circumstances require so, in particular when visibility is poor. RTR 135. Drivers must not: 135.2. exceed the speed limit specified on the vehicle marking plate;  135.3. drive too slowly without reason and hinder the normal traffic of other road users;  135.4. slow down abruptly for other than safety reasons.

RTR – 150. Standing and parking are prohibited: 150.3 on and under bridges, viaducts and flyovers — except where parking is expressly permitted by road signs indicating a parking space — and in tunnels.

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

Although the road sign normally prohibits overtaking, overtaking vehicles traveling at speeds under 30 km/h is permitted provided it can be done safely. Road sign 325 — “Overtaking prohibited” forbids overtaking, except for individual vehicles (or individual vehicle combinations) traveling at speeds under 30 km/h. Road sign 805 — “Validity zone ahead” indicates the length of the zone beyond the sign during which a hazardous road section or other associated signs remain in effect.

Regulation RTR 188: An orange flashing light may be used only when the vehicle obstructs other road users—for example, when the vehicle's loaded or unloaded dimensions exceed permitted limits; when performing work on the roadway; when stopping or standing; when moving at very low speed; when escorting an organized group of cyclists; or when transporting hazardous goods. An orange flashing light does not confer priority; it merely attracts attention and warns other road users of a potential hazard. While driving, standing, or working on the road, drivers of vehicles displaying orange flashing lights must ensure they do not compromise traffic safety.

LAW ON ROAD TRAFFIC SAFETY — Article 2, Section 14. A 'road accident' means an incident occurring on a road in public or private areas where a moving vehicle causes death or injury to persons, or damages or destroys at least one vehicle, a load, the roadway, its structures, or any other property at the scene.

The driver's reaction time is delayed by illness, fatigue, or the influence of alcohol or drugs. Distraction and poor concentration while driving also lengthen reaction time, and reaction speed typically decreases with age. RTR 14. Driving is prohibited if you are not authorized to operate the vehicle, or if you are intoxicated or under the influence of narcotic, psychotropic or other psychoactive substances. A person who is tired or ill must not drive if doing so could endanger road safety. A vehicle must not be entrusted to anyone affected by these factors or without the required authorization for that vehicle type. When operating a vehicle, the driver must comply with the requirements shown on their driving licence.

If the road surface is slippery or the engine delivers strong torque and the revs increase abruptly, the driven wheels can spin. When the driven wheels are at the rear, the rear axle may lose traction; when they are at the front, the front axle may lose traction, which can cause the vehicle to lose stability and skid.

RTR 38. Persons moving in a wheelchair, or guiding a motorcycle, moped, bicycle, motorised two‑wheeled vehicle, electric micromobility device, or pulling (pushing) a sledge or handcart along the shoulder or edge of the carriageway must proceed in single file and only in the direction of traffic. RTR 64. Cyclists must not: 64.1. ride on the carriageway, except in cases permitted by the Rules. RTR 57. Bicycles may be ridden only on cycle tracks, combined footpath/cycle tracks, or cycle lanes; if none of these are available, bicycles may be ridden on a suitable hard shoulder (with asphalt or concrete surfacing). When a right‑side cycle track, combined footpath/cycle track, cycle lane, or suitable hard shoulder is not available or is unsuitable for cycling (for example, pitted), cyclists may use the pavement or ride in single file on the right‑hand lane of the carriageway, keeping to the right edge of the lane, except in the cases specified in paragraph 106 of these Rules and except when cyclists must bypass an obstruction or continue straight where turning right from the first lane is the only permitted manoeuvre. When riding on a hard shoulder, footpath, cycle track, or pavement, a cyclist must yield to pedestrians, must not obstruct or endanger them, and should pass pedestrians at a speed close to walking pace (3–7 km/h), leaving sufficient lateral clearance to ensure safety.

RTR 131. The following speed limits apply outside built-up areas: 131.1. For passenger cars, goods vehicles with a maximum permissible mass up to 3.5 tonnes, motorcycles and tricycles the maximum permitted speeds are: on motorways — 130 km/h from April to October and 110 km/h from November to March; on highways — 120 km/h from April to October and 110 km/h from November to March; 90 km/h on roads with asphalt or concrete pavement; and 70 km/h on other roads. JB

There are no lane direction signs; therefore the driver of the red vehicle may go straight or turn right. When changing lanes, the driver of the green vehicle must yield. RTR 104. When changing lanes, a driver must yield to vehicles moving in the same direction in the adjacent lane. If vehicles moving in the same direction change lanes simultaneously, a driver must yield to the vehicle on the right, except in the cases specified in Paragraph 112 of the Rules. RTR 112. If an acceleration lane is provided for entering the road, the driver must use that lane and merge into the main traffic flow (change lanes and move into the adjacent lane), yielding to vehicles already in that flow or to vehicles changing lanes toward the deceleration lane. RTR 106. Before turning right, left, or making a U-turn (except when entering an intersection with circular traffic), a driver must move in advance to the edge of the carriageway designated for that direction. Road signs and/or road markings may indicate otherwise.

RTR 15. Driving vehicles that are not in good condition and that do not meet the technical requirements for vehicles (hereinafter referred to as "technical requirements") is prohibited. Before setting off, the driver of a motor vehicle, tractor, or self-propelled machine must ensure the vehicle is in proper condition and that it carries a warning triangle, fire extinguisher, first aid kit, and any other items required for specific vehicle types. The driver must also monitor the vehicle's technical condition during the trip. If the vehicle breaks down while driving and therefore does not meet the technical requirements and cannot be repaired, the driver may proceed to the nearest parking area or vehicle repair facility, taking all necessary precautions, except in the cases specified in paragraph 234 of these Rules.

If the vehicles' paths do not intersect, they may proceed simultaneously.

While public transport also produces emissions, it carries many passengers at once; as a result, fuel (or electricity) consumption per person is much lower, noise levels are reduced, and traffic congestion is significantly decreased.

RTR 92. If the vehicle's hazard warning lights are absent or defective and an emergency stop is required where stopping or parking is prohibited, in the event of an accident, or when the stopped vehicle would be visible to other road users from less than 100 metres, the driver of a motor vehicle (excluding a motor moped and motorcycles without a trailer), a tractor, or a self-propelled machine must immediately place an emergency stop sign on the side of the carriageway opposite the direction of travel: within settlements not less than 25 m, and outside settlements not less than 50 m from the stopped vehicle. If at least one rear position lamp is defective and the hazard warning signal is not working when driving in darkness or poor visibility, an emergency stop sign must be affixed to the rear of the vehicle in order to continue driving.

RTR 3.1. "Service vehicles" are vehicles owned by companies, institutions, or organisations operating in an area marked by restrictive signs; vehicles belonging to persons who live or work in that area; vehicles delivering goods to that area or collecting goods from it; and taxis or other passenger vehicles providing paid transport to or from that area.

If a road accident results only in property damage and the owner of the damaged property is not present at the scene and cannot be contacted, the road user involved must immediately notify the owner or, if that is not possible, report the accident to the police. XXIX. Obligations of Road Users in the Event of a Road Accident (paras. 219–222) 219. In the event of a road accident, every driver involved or any other road user must: 219.1. stop immediately without creating further danger to other road users and mark the accident scene as required by subparagraph 91.2 and paragraph 92 of these Rules; 219.2. take all possible measures to ensure safety at the scene, and if the police are called, avoid (without endangering traffic) altering the circumstances of the accident and preserve the traces and evidence of the collision; 219.3. at the request of other road users involved, present a valid identity document or driving licence and a certificate (policy) of compulsory motor third-party liability insurance to identify the insurer; 219.4. if a person has been injured or has died in the accident, report the accident to the police and remain at the scene, or after notifying the police return and wait for them, except where the police permit departure or where the casualties or the person reporting the accident require immediate first aid; 219.5. take all necessary measures to provide first aid to the casualties, call an ambulance or, if calling an ambulance or transporting casualties to a medical facility by other means is impossible, carry them to the nearest medical facility in a private vehicle unless such transport would endanger their life or health. 222. If a road accident causes only property damage and the victim is not present at the scene, the road user involved must immediately notify the victim or, if that is not possible, the police.

Difference between active and passive safety: - Active safety: systems and features that help prevent accidents by improving vehicle control, handling and stability before a collision occurs. These measures operate before an impact and commonly include technologies such as Anti-lock Braking System (ABS), Electronic Brakeforce Distribution (EBD), traction control, correct tyre pressure and adequate tread depth, among others. Active safety also depends on the driver’s condition and behavior — for example, poor ventilation or heating can cause drowsiness or nausea and reduce attention on the road. - Passive safety: systems and equipment designed to reduce injury and damage during or after a collision. These features are activated in a crash to protect occupants and other road users and include seat belts, airbags, motorcycle helmets, seat-belt reminders, head restraints, crumple zones and other structural or restraint systems that absorb impact and lower the risk of injury.

RTR 11D. In heavy traffic, when all lanes are occupied by vehicles, changing lanes is permitted only when necessary to make a turn, make a U‑turn, or stop. JB
