When vehicle speed increases, the layer of water on the road becomes deeper. Heavier rainfall also increases the water layer during driving. On roads with a transverse crown (where the carriageway is higher in the centre), the water layer is thinner because rainwater drains off the surface toward the edges more quickly. On asphalt, a tyre can displace only as much water as the volume available in its tread.

The red and blue vehicles are on the priority (main) road, so they proceed first. Between them the priority-to-the-right rule applies: the red vehicle goes first because no vehicle is approaching from its right, followed by the blue vehicle. Vehicles on the side road follow: the green vehicle goes next (it has no vehicle to its right), and last is the yellow vehicle. RTR 154. At a controlled intersection, drivers on a side road must yield to vehicles on the priority road. RTR 156. If the main road’s direction changes at the intersection, drivers on the main road must, with respect to one another, follow the rules for intersections of roads of equal importance; drivers on the side road must apply those same rules among themselves. RTR Annex 2.204. 'STOP' — drivers must not proceed without stopping before the stop line or, if there is no line, before the sign. A driver must yield to vehicles traveling on the road he or she is about to cross. If panel No. 843 'Direction of Priority Road' is installed below the sign, the driver must yield to vehicles on the priority road.

Motor vehicles are not permitted to tow trailers intended for agricultural tractors due to safety requirements and technical incompatibilities. The term "motor vehicle" excludes non-road rail vehicles, tractors, and self-propelled machines. Per RTR 207, the total weight of carried cargo and passengers and the axle loads must not exceed the gross vehicle weight and axle load limits specified for that vehicle by the Ministry of Transport and Communications of the Republic of Lithuania and by the vehicle manufacturer. The gross weight of a towed trailer (laden or unladen) must not exceed the maximum permissible tow weight established by the Ministry and the manufacturer. Consequently, motor vehicles are prohibited from towing trailers of non-motor vehicles, and non-motor vehicles are prohibited from towing trailers of motor vehicles.

You cannot overtake on the right because you are on a narrow road. Overtaking on the right of a vehicle that is turning left is permitted only if there is sufficient space on the carriageway. RTR 136. Drivers are advised to avoid unnecessary overtaking maneuvers. Before overtaking, drivers must exercise extra caution and ensure that: 136.1 none of the drivers behind has already begun to overtake; 136.2 the driver of the vehicle to be overtaken is not indicating a left turn; 136.3 the portion of lane required for overtaking is clear and the maneuver will not obstruct oncoming vehicles or pedestrians using the carriageway; 136.4 a safe distance from the vehicle being overtaken will be maintained during the maneuver; 136.5 after overtaking they will be able to return to the same traffic lane safely without obstructing the overtaken vehicle. RTR 137. If the vehicle in front is indicating a left turn and has changed lanes to make that left turn (or to turn around), vehicles following must pass the turning vehicle on the right or wait until it leaves the traffic lane.

RTR 201. A child must not be transported in a rear-facing child seat appropriate for their size on a front passenger seat that is protected by an active airbag. This restriction does not apply if the front airbag has been deactivated. It is recommended that a child be carried as long as possible in a child seat suitable for their height and weight and installed rear-facing, contrary to the vehicle’s direction of travel (as specified by the seat manufacturer).

Although driving at high speed increases fuel consumption and accelerates tire wear, those effects are not the primary danger asked about here and therefore should not be selected. Increasing speed lengthens the distance traveled during the driver's reaction time and increases the braking distance (braking distance grows roughly with the square of speed), which reduces the ability to stop before an obstacle. In addition, the centrifugal force acting on the vehicle toward the outside of a curve increases with the square of the speed and is inversely proportional to the curve's radius. As a result, at higher speeds the vehicle is more likely to skid or roll over.

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.

RTR 203. A driver must ensure that children transported in a motor vehicle use the appropriate installed and correctly fitted restraint systems. JB

RTR 16. A driver must stop the vehicle when ordered by an inspecting officer. The driver of a motor vehicle, tractor or self-propelled vehicle shall 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 (including tactical and logistical vehicles) or their combinations with trailers; the vehicle registration documents; the certificate of the compulsory roadworthiness test and 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 any other documents required by the laws of the Republic of Lithuania and these Rules (except in cases 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 meters that record driving time and rest periods. Documents shall be presented without leaving the vehicle. The driver may leave the vehicle only with the inspecting officer's permission. RTR 91. If hazard warning lights are fitted in a vehicle, they must be switched on: 91.3. when the vehicle is stopped by an inspecting officer;

If a bend in the road is sharper than anticipated, you must reduce your speed.

RTR 40. An organised group of children under 16, accompanied by at least two adults, may use pavements, footpaths, or the pedestrian side of shared footpath and cycle tracks if available. If none of these facilities are present, the group may walk along the hard shoulder, but only in daylight hours when visibility is good, in no more than two files walking against the flow of traffic, and only when it is safe to do so. Accompanying adults must be positioned at the front and rear of the column and wear high-visibility vests. It is recommended that all children in the organised group wear high-visibility vests when walking along the hard shoulder.

131. The following speed limits apply outside built-up areas: 131.2. Vehicles of categories A1, A2, A or B driven by novice drivers, persons learning to drive or taking a practical driving test, and buses (including school buses) are subject to the following maximum speeds: 100 km/h on motorways, 90 km/h on highways, 80 km/h on roads with asphalt or concrete pavement, and 70 km/h on other roads.

If you press the accelerator suddenly on a slippery road, the driving wheels may start to spin, further smoothing and polishing the wheel track on the slippery surface. This reduces traction; as a result the tires can lose grip more quickly and the vehicle may skid or slide sideways.

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

Under Article 23 of the Law on Road Traffic Safety, there are two ways to obtain a category A (motorcycle) driving licence. You may obtain category A from the age of 24 without prior experience. Alternatively, from the age of 20 you may obtain category A if you have at least two years' qualifying experience riding category A2 motorcycles. The two-year A2 experience requirement does not apply to applicants aged 24 or older. Separately, the right to drive tricycles (three-wheelers) with power exceeding 15 kW is granted from the age of 21.

A safe speed depends on all circumstances, including weather, road surface and vehicle condition, as well as the driver's experience and level of alertness. (RTR 127) Drivers must not exceed the permissible speed limits. A driver must choose a speed appropriate to the conditions — taking into account terrain, road and vehicle condition (including load), weather, and traffic density — so that they can stop safely before any foreseeable obstruction. The driver must reduce speed or stop when conditions require, particularly when visibility is poor. JB

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.

91. If a vehicle is equipped with hazard warning lights, they must be used: 91.7 when other road users should be warned of an obstruction or hazard.

RTR 219. In the event of a road accident, every driver involved or any other road user must: 219.3. upon the request of other road users involved in the accident, present a valid identity document or a valid driving licence, and a certificate (policy) of compulsory third‑party motor vehicle liability insurance in order to identify the insurer;

RTR 107. If, because of large dimensions or other reasons, a vehicle cannot turn (or make a U‑turn) from the edge position, it may execute the turn from a location other than the lane edge designated for travel in that direction, provided the manoeuvre does not obstruct other vehicles or create hazards for other road users.

RTR 92. If the emergency light signaling 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 place an emergency stop sign on the carriageway side opposite the direction of travel: in built‑up areas not less than 25 m from the stopped vehicle, and outside built‑up areas not less than 50 m. If at least one rear position lamp is defective and the hazard warning lights are not working when driving at night or in poor visibility, an emergency stop sign must be affixed to the rear of the vehicle in order to continue driving. RTR 151. When a vehicle is forced to stop where standing or parking is forbidden, drivers must switch on their hazard warning lights if available and/or place a warning triangle on the road as specified in Paragraph 92 of the Rules and remove their vehicle from the road as soon as possible. If drivers intend to stop their vehicle on unlit sections of the road during darkness or when visibility is poor, and hazard warning lights are not available or are inoperative, the vehicle must be parked off the carriageway. If this is impossible, the location must be marked as specified in Paragraph 92 of the Rules. JB

According to rule 131.1: On motorways, from April to October the maximum speed for passenger cars, goods vehicles with a permissible maximum weight up to 3.5 tonnes, motorcycles, and tricycles is 130 km/h, and from November to March it is 110 km/h. On expressways (highways) the limit is 120 km/h from April to October and 110 km/h from November to March. On roads with asphalt or concrete pavement the limit is 90 km/h, and on other roads it is 70 km/h.

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 12. Road users must immediately yield to approaching emergency vehicles that display blue and red (or only blue) flashing lights and use special audible signals, as well as to vehicles escorted by them. Road users shall form an emergency corridor as follows: 12.1 On a road with a single lane in one direction, drivers must stop on the right hard shoulder if one exists; if there is no hard shoulder, they must stop as close as possible to the right edge of the carriageway. 12.2 On a road with two or more lanes in the same direction, vehicles in the far-left lane must move and stop as close as possible to the left edge of the carriageway designated for that direction, while vehicles in the lanes to the right must move and stop as close as possible to the right edge of the carriageway (or the hard shoulder). 12.3 On a road with a central reservation, only drivers travelling in the same direction must comply with the requirements in paragraphs 12.1 and 12.2. RTR 154. At a controlled intersection, drivers on a side (minor) road must yield to vehicles approaching on the priority road.

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.

Selecting an appropriate heating/ventilation setting will reduce condensation on the windows; using the windscreen wipers will clear fogged windows and maintain good visibility; switching on the fog lamps will make the road more visible and help other road users notice you. RTR 98. Fog lamps may be used only when visibility is seriously reduced, and the front fog lamps may be used in the event of failure of the front left dipped‑beam headlamp. Poor visibility means a situation caused by weather conditions or other phenomena when road visibility is less than 300 metres, regardless of road parameters.

Causes of premature clutch wear include an improperly adjusted clutch release mechanism, loose clutch mounting screws, weakened clutch springs, or a worn gearbox primary shaft.

Answers 1–3 are methods to lower fuel consumption and reduce pollution. Answer 4 is incorrect — driving closely behind the vehicle ahead to reduce air resistance is unsafe.

Driving livestock or birds on a road is uncommon, but drivers should know the minimum permitted age because it is specified in the Road Traffic Rules. RTR 5. Road users must be familiar with the Law of the Republic of Lithuania on Road Traffic Safety, know the Rules, and comply with them. RTR 67. Only persons over the age of 14 may drive an animal-drawn vehicle, drive livestock or birds, or ride an animal on the road.
