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.

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;

RTR 107. When, due to a vehicle's large size or other valid reasons, it is not possible to complete a turn (turn around) from the appropriate edge position of the carriageway, the vehicle may perform the turn from a part of the carriageway other than that edge assigned for travel in that direction, provided the maneuver does not obstruct other vehicles or create a hazard for other road users. JB

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.

129. The maximum speed limit within built-up areas for all vehicles is 50 km/h.

To drive economically and sensibly, begin moving smoothly and progressively. Reduce your speed gradually within your capabilities, and avoid unnecessary abrupt maneuvers unless they are essential (for example, emergency braking to avoid an unexpected obstacle). When you accelerate suddenly from a standstill, tyres experience increased wear during rotation.

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.

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

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 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 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.

Road sign 334 — “No parking on odd days”. Parking is prohibited on the side of the road where this sign is placed on odd-numbered days of the month. Road sign 335 — “No parking on even days”. Parking is prohibited on the side of the road where this sign is placed on even-numbered days of the month. When signs 334 and 335 are installed on both sides of the road, vehicles must be moved from one side to the other between 19:00 and 24:00 (7:00 pm–12:00 am); during that interval, parking is permitted on either side of the road.

Stationary vehicles positioned before a pedestrian crossing restrict visibility. Drivers must exercise extra caution and may continue only after confirming that no pedestrians entitled to right of way are at the crossing. (RTR 30.) When approaching an uncontrolled pedestrian crossing, a driver must reduce speed or stop before the crossing to give way to pedestrians who have already entered any lane, are walking in any lane, or were standing immediately at the carriageway edge waiting to step into a lane in the direction of the vehicle’s travel—or into any lane on a road with one lane in each direction. Drivers must be especially careful at night, in poor visibility, or whenever the crossing is not clearly visible from the driver’s position, and must ensure there are no pedestrians who should be given way.

Drivers should check that all vehicle lights are working before every long journey and at least once every six months. Properly functioning lights help you assess road conditions accurately and reduce the risk of accidents.

3. Terms used in the Road Traffic Rules: 3.2. 'Give way' means that drivers must stop, or must not begin to drive or manoeuvre, if doing so would require other vehicle drivers to change their direction of travel or their speed.

On roads with four or more lanes, a double solid line separates opposing traffic flows. It prohibits driving in lanes that carry traffic in the opposite direction on the marked section; vehicles must not cross this line.

A vehicle's permissible maximum weight (hereinafter 'permissible maximum weight') means the maximum authorized operating weight of a fully laden vehicle or combination of vehicles, including the driver, passengers, and cargo, as specified by the vehicle manufacturer or the competent government authority.

Any load that projects laterally, even slightly, must be marked. During hours of darkness such a load must be indicated by lights. Loads projecting beyond the sides of the vehicle must always be marked; loads projecting beyond the front or rear do not always require marking. According to RTR 210 and Annex 4: loads extending more than 1 m beyond the front or rear of the vehicle, or projecting laterally beyond the vehicle's outer edge, must be marked as specified in Annex 4.12. Extreme edges of loads that extend more than 1 m beyond the vehicle's dimensions, or that project even minimally to the side, as well as extreme edges of vehicles wider than 2.6 m, shall be marked with distinguishing panels — 400 mm square plates with alternating reflective white and red diagonal stripes 50 mm wide. These panels must be mounted between 0.4 m and 1.6 m above ground level. During hours of darkness or in poor visibility such vehicles must also display lights in the designated positions: white at the front, orange at the sides, and red at the rear.

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.

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.

The primary characteristics of a driver's will are discipline, determination, self-control, and perseverance. Disciplined drivers consistently obey the rules of the road (RTR). Determined drivers do not hesitate about decisions they make while operating a vehicle. A driver's self-control is demonstrated by remaining calm in complex traffic situations and by showing respect for other road users. Perseverance is the ability to overcome difficulties encountered on the road.

An anti-lock braking system (ABS) prevents wheel lockup during heavy braking, helping to maintain tire traction and steering control—especially on slippery surfaces. When wheels lock, the vehicle can skid and the driver may lose the ability to steer. ABS modulates brake pressure to preserve grip and directional stability.

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.

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.

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 – 51. When an inspecting officer stops a vehicle, passengers may exit the vehicle only with the officer's authorization.

A vehicle's braking system is intended to slow the vehicle, bring it to a complete stop, and hold it stationary. Braking distance should be kept as short as possible, and you must maintain control of the vehicle while braking.

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.

On unlit roads it is permitted to use high‑beam headlights. According to regulation RTR 95, during hours of darkness or in conditions of poor visibility high beams must be switched to low beam on illuminated roads (see 95.1).
