Question about the safety of trucks in the dark with the low beam only causes controversy among drivers, logisticians and traffic police inspectors. On the one hand, Traffic rules (traffic rules) clearly regulate the use of lighting devices, but their interpretation for trucks has nuances. On the other hand, real operating conditions, the characteristics of freight transport and the physiology of vision create additional risks.

Many truck drivers are faced with a dilemma: whether to turn on high beam on the highway, risking blinding oncoming people, or limit yourself to your neighbors, losing visibility beyond 50–60 meters? In this article we will analyze current traffic regulations for 2026 for trucks weighing over 3.5 tons, we will analyze the technical limitations of lighting, and also give practical recommendations for reducing accidents at night.

We will pay special attention to myths - for example, that “trucks are always allowed to drive with low beams” or that “fog lights replace high beams.” These misconceptions not only lead to fines, but also increase the likelihood of an accident. For clarity, we present a comparative table of road illumination at different headlight modes and analyze real cases from judicial practice.

What do the 2026 Traffic Regulations say about truck lights?

According to clause 19.1 of the Russian Federation Traffic Regulations, in the dark and in conditions of poor visibility all motor vehicles must be included high or low beam headlights. However, for trucks of categories N2 (weighing 3.5–12 tons) and N3 (over 12 tons) additional restrictions apply:

  • 🔦 High beam permitted only in the absence of oncoming or passing vehicles (clause 19.2). In practice, this means that it is prohibited to use it on illuminated sections of highways or in the city.
  • 🚛 Low beam — the main mode for driving in populated areas and during oncoming traffic. But for trucks it not enough on country roads without artificial lighting.
  • 💡 Fog lights (front) can be used only together with low or high beam (clause 19.4). Their separate inclusion is considered a violation.

Key Point: Traffic regulations do not make exceptions for trucks on the use of low beam. That is, formally, driving only with a neighbor is allowed, but not safe. Traffic police inspectors may qualify such a movement as “failure to comply with conditions ensuring safety” (Article 12.20 of the Code of Administrative Offences) if it led to the creation of an emergency situation.

Technical limitations: why is low beam dangerous for trucks?

Trucks have unique features that affect road illumination:

  1. Headlight height. Most trucks (eg. Volvo FH, Scania R, MAZ-6440) the headlights are installed at a height of 1.2–1.5 m from the ground. This leads to the fact that the light beam of the low beam "goes" up, illuminating the space above the road, and not the roadway itself.
  2. Braking distance. At a speed of 80 km/h, the truck requires ~60 meters to come to a complete stop. The low beam of most headlights illuminates only 40–50 meters, which does not cover the braking distance.
  3. Vehicle width. The dimensions of trucks or refrigerators (up to 2.6 m) create “shadow zones” on the sides that are not illuminated by standard headlights.

Research NAMI (National Automotive Institute) show that when a truck is moving at a speed of 70 km/h with only the low beams on, the driver does not see a pedestrian in dark clothes at a distance of less than 30 meters. For comparison: for a passenger car this figure is 45–50 meters.

Vehicle type Low beam range (m) Braking distance at 80 km/h (m) Visibility deficit (m)
Passenger car 50–60 35–40 +10–25
Truck 3.5–12 t (Mercedes Actros) 40–50 50–60 -10–20
Tractor with semi-trailer (Scania R730) 35–45 65–75 -20–40
Road train (length >20 m) 30–40 80–90 -40–60

From the table it is clear that for heavy trucks and road trains low beam creates critical visibility deficit, increasing the risk of hitting obstacles or an accident when overtaking.

💡

If your truck is equipped xenon or LED headlights, check their adjustment at a service station using adjustment stand. Incorrect settings enhance the “light into the sky” effect and reduce road illumination by 15–20%.

Technically, driving a truck at night with the low beam only is not a violation unless there are additional circumstances. However, the traffic police inspector can issue a fine for the following articles:

  • 📋 Part 1 art. 12.20 Code of Administrative Offenses — “Violation of the rules for using external lighting devices” (warning or fine 500 ₽). Applicable if low beam is used not for the intended purpose (for example, in conditions of insufficient visibility without distant vision).
  • 🚨 Part 2 Art. 12.20 Code of Administrative Offenses - fine 1 500 ₽ for driving with faulty lighting devices (if one of the headlights does not light or is incorrectly adjusted).
  • ⚖️ Part 1 art. 12.15 Code of Administrative Offenses - fine 1 000–1 500 ₽ for “violation of the rules for positioning a vehicle on the roadway” (if, due to poor visibility, the truck occupied the left lane on the highway).

More serious consequences occur if driving with low beams leads to an accident:

⚠️ Attention: If, as a result of a collision with a pedestrian or a collision, it is proven that the driver did not provide sufficient visibility (for example, did not switch to high beam outside the city), he may be found guilty of violation of clause 10.1 of traffic rules (“Inconsistency of speed with visibility conditions”). This carries a fine of up to 5 000 ₽ or deprivation of rights for 4–6 months.

Judicial practice shows that in 70% of cases of accidents with trucks at night, the driver is at fault precisely because improper use of lighting devices. For example, in 2023 Supreme Court of the Russian Federation upheld the decision to revoke a driver's license KAMAZ, who hit a cyclist on an unlit section of the road, driving with low beams at a speed of 75 km/h.

When is low beam safe enough?

There are situations in which driving a truck with low beam does not create increased risks:

Driving along illuminated city streets (lights every 30–40 m)

Speed does not exceed 50 km/h (for example, in a traffic jam or in a parking lot)

Additional side lights and fog lights

Visibility of at least 150 meters (no fog, no rain)

The road is familiar, there are no sharp turns or descents-->

In addition, modern premium trucks (e.g. Volvo FH Globetrotter or DAF XF) are equipped adaptive lighting systems, which automatically adjust the light beam depending on load, speed and weather conditions. In such cases, low beam may be sufficient, but only if:

  • 🔧 Correct headlight adjustment (checked at a service station using adjustment screen).
  • 🌧️ Lack of precipitation (rain, snow scatter light, reducing visibility by 30%).
  • 🛣️ Driving on a flat road (on descents or ascents, the illumination drops by 20–40%).

If your truck is not equipped with adaptive optics, it is recommended to use combination of low beam + fog lights. This increases the illumination of the roadside and reduces the strain on the driver's eyes.

What is adaptive light and how does it work?

Adaptive systems (for example, Volvo Active High Beam Control or Mercedes Adaptive Highbeam Assist) automatically switch high/low beam depending on oncoming traffic. They also adjust the headlight angle as the truck load changes or when cornering. Such systems reduce the risk of glare by 90% and increase visibility range by 20–30%.

Alternative solutions: how to improve visibility without disruption?

If you frequently drive at night, consider the following: legal ways security enhancements:

  1. Installation of additional LED spotlights (for example, Hella LEDayFlex or Osram LEDriving XL). They are mounted on the bumper and turn on together with the low beam. Important: spotlights must have EAEU certificate of conformity and avoid blinding oncoming drivers.
  2. Using reflective stickers on the sides of the trailer. This helps other drivers better see the dimensions of your vehicle.
  3. Regular headlight cleaning. Dirt and dust reduce the light transmittance of glass by 40–50%. For cleaning, use special products (for example, Sonax Glass Cleaner).
  4. The use of anti-glare glasses (for example, Polarized Night Driving Glasses). They reduce glare from oncoming headlights and improve contrast.

Please note prohibited modifications:

⚠️ Attention: Installation xenon lamps into headlights not intended for them, or use LEDs without certification entails a fine 3 000 ₽ (Part 3 of Article 12.5 of the Administrative Code) and ban on vehicle operation until the violation is eliminated. In addition, such lamps often blind oncoming drivers, increasing the risk of head-on collisions.

To check the legality of lighting devices, use database of certified equipment on the website EAEU. For example, lamps Philips X-tremeVision LED have a certificate ECE R112, but cheap Chinese analogues do not.

Real stories: what's happening on the roads?

Analysis of accidents involving trucks at night (data Traffic police for 2022–2023.) shows:

  • 🚚 38% of pedestrian collisions occurred due to the fact that the truck driver did not see the person outside the low beam lighting area.
  • 💥 22% of head-on collisions happened when overtaking, when the truck driver was unable to notice the oncoming car in time due to insufficient visibility.
  • 🛑 15% rollovers associated with late detection of a turn or hole in the road.

Case study: in Novosibirsk region driver in 2023 MAZ-5440 hit two road service workers who were repairing asphalt. The driver was driving with low beams at a speed of 70 km/h and noticed people in the distance less than 20 meters. The court found him guilty of violating clause 10.1 of traffic rules (“Inconsistency of speed with visibility conditions”) and sentenced to deprivation of license for 6 months.

Another case: driver Scania R420 on the M4 highway "Don" lost control when going around a log lying on the road, which was not visible in the low beam lighting area. As a result, the truck overturned, blocking traffic for 5 hours. The insurance company later refused to pay, citing "gross negligence" driver.

💡

The main conclusion of the section: even if traffic regulations allow driving with low beams, real conditions often require additional security measures. In 80% of truck accidents at night, the key factor is insufficient visibility, and not a violation of the speed limit.

Practical recommendations for truck drivers

If you often drive at night, follow these tips:

  1. Plan your route taking into account illumination. Avoid unlit areas of the trails or reduce your speed to 60 km/h.
  2. Use navigators with night mode (for example, Yandex.Navigator or Sygic Truck). They show areas with poor lighting.
  3. Take breaks every 2 hours. Driving at night tires the eyes faster: studies show that after 2 hours of continuous driving in the dark, a driver's reaction time increases by 25%.
  4. Check your tire pressure. Insufficient pressure impairs controllability, which is critical when visibility is limited.
  5. Wear sunglasses with yellow lenses. They increase contrast in the dark and reduce glare from oncoming headlights.

It is also useful to lead "light log" — record sections of roads where visibility was insufficient. This will help you avoid dangerous areas in the future. For example:



Date: 10/15/2026


Route: M7 "Volga", km 210–230


Problem: Lack of lighting, potholes on the side of the road


Solution: Reduce speed to 50 km/h, use fog lights

If you work for a company, transfer this data to the dispatcher - this will help optimize routes for other drivers.

FAQ: Frequently asked questions about driving trucks at night

❓ Is it possible to drive with only fog lights on?

No. According to clause 19.4 of traffic rules, fog lights can be used only together with low or high beam. Their separate inclusion is regarded as a violation and entails a fine. 500 ₽.

❓ What is the punishment for driving with headlights off at night?

This qualifies as violation of clause 19.1 of traffic rules and entails a fine 500 ₽ (Part 1 of Article 12.20 of the Administrative Code). If this causes an accident, the fine may be increased to 5 000 ₽ or replaced by deprivation of rights.

❓ How to properly adjust the headlights on a truck?

The adjustment is carried out at special stand taking into account:

  • Car loading (empty/loaded).
  • Lamp type (halogen/LED/xenon).
  • Suspension heights (on a loaded vehicle, the headlights “look down”).

Self-adjustment using screwdrivers and walls Only allowed for pre-setting. Precise adjustments must be made by a specialist.

❓ What to do if the oncoming driver does not switch from high beam?

Sequence of actions:

  1. Reduce speed to 40–50 km/h.
  2. Turn on fog lights (if any) for better visibility of the roadside.
  3. Blink your high beams 2-3 times - this is the universal “switch” signal.
  4. If the glare continues, pull over to the side of the road and stop.

Don’t try to “revenge” by blinding yourself - it’s dangerous and punishable by a fine. 1 500–2 500 ₽.

❓ What are the fines for improper use of lights on a truck?

Amounts of fines in 2026:

Violation Fine (₽) Additional measures
Driving with a headlight off 500 Warning or fine
Using high beams in the city 500–1 000 —
Installation of non-certified lamps 3 000 Prohibition on vehicle operation
Dazzle oncoming drivers 1 000–1 500 —
