A driver must maintain clear forward visibility in all weather conditions. Use the windscreen wipers according to the intensity of precipitation, traffic, presence of pedestrians and other circumstances. Waiting until "the windscreen is covered in snow and you are unable to see anything" is too late.

IV 15. It is prohibited to drive vehicles that are not in good condition or that fail to meet the applicable technical requirements. Before setting off, the driver of a motor vehicle, tractor, or self-propelled vehicle must ensure the vehicle is in proper condition and is equipped with a warning triangle, fire extinguisher, first-aid kit, and any other items mandated for that vehicle type. The driver must also monitor the vehicle's technical condition during the trip. If the vehicle breaks down while driving and ceases to meet technical requirements, and repairs on-site are impossible, the driver may proceed—taking all necessary precautions—to the nearest parking area or repair facility, except in cases specified in paragraph 234 of these Rules.

Battery capacity decreases as ambient temperature falls. A fully charged battery that measures 100% capacity at +25 °C will typically drop to about 80% at 0 °C and to roughly 60% at −25 °C.

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.

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.

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.

Regulation RTR 98: Fog lamps may be used only when visibility is severely reduced. Front fog lamps may also be used if the left front dipped-beam headlamp has failed. According to the Law on Road Traffic Safety, Article 2(5), 'poor visibility' means a situation caused by weather or other phenomena in which road visibility is less than 300 metres, regardless of road characteristics.

When driving with tyres that have insufficient air pressure, the outer edges of the tyres wear more quickly, shortening tyre lifespan. Low tyre pressure also reduces vehicle stability and increases rolling resistance, which raises fuel consumption.

Stopping distance is the distance a vehicle travels from the moment the driver notices an obstruction until the vehicle comes to a complete stop. Braking distance is the distance the vehicle travels from the moment the brakes are fully applied until it stops. Reaction distance is the distance the vehicle travels from the moment the driver detects an obstruction until the driver begins to apply the brakes.

When driving under the influence of alcohol, attention and comprehension are reduced; critical thinking and memory are impaired; coordination of movements deteriorates; reflexes are weakened or lost; drivers take longer to perceive signals and interpret situations; overall driving performance declines, reaction times slow, and vehicle control worsens or may be lost.

RTR 143. Stopping on unlit sections of road during hours of darkness or when visibility is poor is permitted only with hazard warning lights activated. Parking is allowed only in designated car parks or in areas off the carriageway.

The AM category is sufficient to drive these vehicles, but it is not the only entitlement that allows you to do so. Possessing another driving category that authorises operation of such vehicles also permits you to drive them. LAW ON ROAD TRAFFIC SAFETY — Article 2. Basic concepts of the Law: 30. Light quadricycle means a four-wheeled motor vehicle with an unladen mass (excluding batteries if it is an electric vehicle) not exceeding 350 kg, a maximum design speed not exceeding 45 km/h, an engine capacity not exceeding 50 cm3 (for a spark-ignition engine), a maximum net power not exceeding 4 kW (for another type of internal combustion engine), and a maximum rated power not exceeding 4 kW (for an electric motor). 33. Moped means a two-wheeled motor vehicle with a maximum design speed exceeding 25 km/h and not exceeding 45 km/h, an engine capacity not exceeding 50 cm3 (for an internal combustion engine), and a maximum net power not exceeding 4 kW (for an electric motor); or a three-wheeled motor vehicle with a maximum design speed exceeding 25 km/h and not exceeding 45 km/h, an engine capacity not exceeding 50 cm3 (for a spark-ignition engine), a maximum net power not exceeding 4 kW (for another type of internal combustion engine), and a maximum net power not exceeding 4 kW (for an electric motor). LAW ON ROAD TRAFFIC SAFETY — Article 23. Categories of motor vehicles and the minimum driving age: 1. Categories of motor vehicles and their combinations with trailers: 1) Category AM: mopeds and light quadricycles;

Driving across a level crossing where the traffic lights are switched off and the barrier is raised or absent is permitted, but only if you obey traffic regulations and ensure that no train is approaching. 168. Before entering and crossing a level crossing, a road user must comply with road signs, road markings, the position of the barrier, traffic lights, audible warnings, and the signals given by level crossing attendants/controllers. Before entering a level crossing, a road user must always verify that no rail-borne vehicle is approaching the level crossing. It is recommended that children under 12 be accompanied when crossing a level crossing. 173. Drivers must not: 173.3. enter a level crossing after the barrier has been lowered or has begun to be lowered, willfully lift the barrier or manoeuvre around the barriers;

Passengers may be carried in a towed vehicle except when the vehicle is being towed with its front or rear supported on a towing platform or other support device. Regulation 195 states that drivers must not: 195.4. carry passengers inside a bus, trolleybus, or the body of a goods vehicle that is being towed; if the front or rear of a vehicle is resting on a support device, passengers must not be inside the vehicle or in its cargo body.

RTR 217. The following vehicle towing and transport practices are prohibited: 217.6. Towing more than one motor vehicle, tractor, or self-propelled vehicle.

Using the horn may distract the driver being overtaken but will not prevent the overtaking; they may still accelerate to complete the manoeuvre. Obstructing an overtaking vehicle includes actions such as accelerating, steering toward the overtaking vehicle, blocking the lane, or any other behaviour intended to prevent another driver from passing. RTR 138. The driver of a vehicle being overtaken must not obstruct drivers who wish to pass by speeding up or by any other action. RTR 136. Drivers are advised to avoid unnecessary overtaking manoeuvres. Before overtaking, drivers must take extra precautions and ensure that: 136.1. no driver behind them has already begun to overtake; 136.2. the driver of the vehicle to be overtaken is not signalling a left turn; 136.3. the section of lane required for overtaking is clear and the manoeuvre will not obstruct oncoming vehicles or pedestrians on the carriageway; 136.4. a safe distance from the vehicle being overtaken can be maintained during the overtaking; 136.5. after the overtaking manoeuvre they will be able to return to the same traffic lane safely without obstructing the overtaken vehicle.

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: 219.4. if a person has died or has been injured in the road accident, report the accident to the police and remain at the accident scene or, after notifying the police, return to the scene and wait for the police to arrive, except where the police permit the road user to leave the scene or when the casualties or the person who reported the accident require first aid; 220. If no deaths or injuries occurred in the road accident and the road users involved agree on the circumstances and do not call the police to the accident scene, the road users must draw the accident sketch on the Road Accident Report Form, describe the circumstances in writing, and have it signed by all road users involved. If none of the road users involved has the Road Accident Report Form, the circumstances may be described and the accident sketch drawn on a blank sheet of paper listing all road users involved, their vehicles, and witnesses, and all details and circumstances must be confirmed by the signatures of the road users involved. Where the circumstances of the accident are disputed, the police must be called to the scene.

Under amendments to the Law on Road Traffic Safety that took effect on 1 January 2015, novice drivers (those with less than two years' driving experience) are considered intoxicated if the alcohol concentration in their breath or bodily fluids exceeds 0. LAW ON ROAD TRAFFIC SAFETY, Article 2, clause 43 defines 'condition under the influence of alcohol' as the state when the concentration of ethyl alcohol in a biological medium of the body (breath, blood, urine, saliva, or other bodily fluids) exceeds the statutory permissible limit. The general maximum permitted concentration of ethyl alcohol in breath, blood, urine, saliva, or other bodily fluids while driving is 0.4 per mille. However, novice drivers, taxi drivers, drivers of mopeds, motorcycles, tricycles, light quadricycles, quadricycles, powerful quadricycles, drivers of vehicles with a maximum permissible mass exceeding 3.5 tonnes or with more than nine seats, and drivers carrying dangerous goods are considered intoxicated when the ethyl alcohol concentration in their breath, blood, urine, saliva, or other bodily fluids is more than 0 per mille.

I. Horizontal marking: 1.11. A WIDE LINE is drawn across the carriageway (the 'Stop' line) and indicates the location where drivers must stop before a 'STOP' sign (at uncontrolled intersections), a red traffic light, or a stop signal given by a traffic officer.

If other drivers switch their headlights from high beam to low beam (flash) during the day, it may indicate that your low beams are excessively bright or misaligned and are dazzling other road users. This is dangerous because dazzled drivers can become disoriented and cause accidents. If you notice that drivers often flash their lights as they pass you, it is a sign to have your vehicle's lighting checked and, if necessary, adjusted. 81. The warning signals are as follows: using turn and brake light signals (signals may also be indicated by hand); sounding the horn; switching headlights on and off; using hazard warning lights; turning on flashing orange hazard lights; and placing a warning triangle on the road or attaching it to a vehicle.

LAW ON ROAD TRAFFIC SAFETY, Article 2, item 43. Intoxication — the state of a person who has consumed ethyl alcohol, when the concentration of that alcohol in the body's biological media (exhaled air, blood, urine, saliva or other bodily fluids) exceeds the legal limit. The maximum permitted concentration of ethyl alcohol in the exhaled air, blood, urine, saliva or other bodily fluids of persons driving vehicles is 0.4 per mille. Novice drivers, taxi drivers, and drivers of mopeds, motorcycles, tricycles, light quadricycles, four-wheel power quadricycles, vehicles with a maximum permissible weight over 3.5 t or with more than 9 seats, and drivers transporting dangerous goods are considered intoxicated when the concentration of ethyl alcohol in their exhaled air, blood, urine, saliva or other bodily fluids is greater than 0 per mille. JB

RTR 175. In residential areas, pedestrians are permitted to walk on the roadway but must not obstruct vehicle traffic. Vehicles are required to yield to pedestrians in these areas.

Carrying unnecessary luggage increases fuel consumption and causes additional harmful emissions. Loud music from a vehicle contributes to noise pollution and can scare wildlife. For short trips, people can walk, cycle, or use public transport, because during brief journeys the engine often does not reach its optimal operating temperature, the vehicle runs less efficiently, and pollution is higher.

If the steering wheel becomes very easy to turn, the vehicle's tyres have likely lost traction on the slippery road surface. In this situation, you must reduce your speed gradually — abrupt throttle changes or hard braking can cause the vehicle to skid or lose control.

Road sign 304 — "No entry for goods vehicles." Entry is prohibited for goods vehicles and vehicle combinations whose permissible maximum mass exceeds 3.5 tonnes or the weight shown on the sign. Tractors and self‑propelled vehicles are also prohibited, except for service vehicles.

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.

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 82. A driver must indicate intended manoeuvres by using the vehicle's left or right turn indicators, or by arm signals if the indicators are unavailable or inoperative. 82.1. Signals must be given before starting to move and before stopping. RTR 86. Warning signals must be given to other road users with sufficient advance notice before the manoeuvre (including any braking related to the manoeuvre) and must be discontinued immediately after the manoeuvre (hand signals may be stopped before the manoeuvre is completed). Signals must be given in a way that does not mislead other road users. Turn indicators are not used when entering a roundabout where traffic circulates in a circle. JB

RTR 8. In the Republic of Lithuania, traffic may be regulated only by road signs listed in Annex 1 to the Rules, by variable message signs treated as road signs (examples are given in Annex 2), by road markings specified in Annex 3, by traffic lights, and by signals from traffic officers, as provided for in these Rules and other legal acts governing traffic control. If the requirements of a road sign conflict with those of a road marking, the road sign must be obeyed. When variable message signs are in use, their indications must be followed. Signals given by traffic officers take precedence over traffic lights, road signs, road markings, and the provisions of these Rules. Road users must comply with the signs that apply to them.

The letter 'R' denotes a radial tyre construction. In a radial tyre, the carcass cords run from one bead to the other in a radial direction instead of being wrapped around the bead cores. Thin, flexible crown plies provide the tread area with the required rigidity and flexibility while minimizing elastic deformation.
