Turning on headlights during the daytime is a topic that has caused controversy among drivers for several years now. Some consider this a meaningless formality, while others consider it a mandatory requirement for safety. Meanwhile, requirement to drive with headlights on during the day enshrined in the traffic rules of most countries, including Russia. But why did this rule appear, how does it affect accident rates and what happens if you ignore it?
In this article we will examine not only the legal side of the issue, but also the physical basis of visibility on the road. You will learn how daytime running lights (DRL) or low beams help to avoid accidents, why in some countries they are fined for this and not in others, and how to properly set the lighting so as not to blind oncoming drivers. We will also debunk popular myths - for example, that turning on headlights drains the battery or that they are only needed in cloudy weather.
Spoiler alert: research shows that using headlights during the day reduces the number of frontal collisions by 10–15%. But there are nuances that not everyone knows about.
1. What the law says: Traffic rules 2026 and fines for non-compliance
In Russia, the requirement to turn on headlights during the day is stipulated in clause 19.5 of the traffic rules. According to him, during daylight hours all moving vehicles must be included:
- 🔆 Low beam headlights - on most cars;
- 🔆 Daytime running lights (DRL) - if they are provided for by the design;
- 🔆 Fog lights - only instead of low beam, but not together with it.
Exceptions are made for motorcycles (they are allowed to drive with their headlights on in any mode) and bicycles (reflectors are enough for them). For non-compliance with the rule in 2026, fine 500 rubles (part 1 of article 12.20 of the Administrative Code). However, in practice, traffic police inspectors rarely stop people only for this violation - usually it is recorded “in combination” with other offenses.
Interestingly, in Europe the requirements are stricter: for example, in Germany or Finland Driving without daytime running lights can result in a fine of up to 80–100 euros. And in Scandinavia This rule has been in effect since the 1970s, where it has been proven that it reduces the number of accidents in polar day conditions.
⚠️ Attention: If you have installed xenon or LED headlights, make sure they are certified for day use. Some models shine too brightly and can blind oncoming drivers, which will lead to a fine under Part 3 of Article 12.5 of the Code of Administrative Offenses (up to 5,000 rubles).
2. The physics of visibility: why headlights save lives during the day
The main reason why headlights need to be turned on during the day is contrast. A person notices a moving object better if it stands out against the background of its surroundings. In sunny weather, a car without headlights on blends into the road, especially if its color is close to asphalt (gray, black, dark blue).
Research Research Institute of Automobile Transport show that:
- 📉 Without headlights, the driver notices an oncoming car 2–3 seconds later;
- 🚗 With enabled DRL or low beams, the likelihood of a frontal collision is reduced by 12%;
- 🌫 In cloudy weather or at dusk, the effect is even more noticeable - up to 20%.
The fact is that the human eye is tuned to perceive dynamic light sources. Even if the sun is shining brightly, flashing or moving lights attract attention faster than a static car silhouette. This is especially important on tracks where speeds are high and reaction time is minimal.
By the way, this is why in Japan and Canada be sure to use headlights even during the day - they have proven that this reduces the number of collisions with pedestrians in 8–10%.
Daytime running lights don't so much illuminate the road as they make your car more visible to other road users.
3. Myths about daytime running lights: what is true and what is not
There are many rumors surrounding the mandatory use of headlights during the day. Let's look at the most popular ones.
Myth 1: “Headlights drain the battery during the day”
❌ Reality: Modern generators can easily cope with loads from DRL or low beam. Even if you are stuck in a traffic jam, energy consumption is minimal - approx. 5–10 W for LED lights. For comparison, the air conditioner “eats” 2–4 kW.
Myth 2: “You don’t need headlights during the day if the weather is good”
❌ Reality: Just in clear weather, the contrast between the car and the road is minimal. On a cloudy day or rain, the car is already more visible due to the wet asphalt and fog.
Myth 3: “DRL is enough, low beam is not necessary”
✅ Reality: If your car has certified daytime running lights (for example, on Toyota Corolla, Volkswagen Polo or Hyundai Solaris), they can actually be used instead of low beams. But if DRL missing or broken, turn on low beam necessarily.
Myth 4: “Fog lights can be used instead of low beams”
⚠️ Reality: According to traffic rules - yes, but only if they are installed front and comply with GOST. Turn on rear fog lights during the day prohibited (fine 500 rubles).
Why have some countries abolished mandatory daytime running lights?
B the Netherlands and Belgium canceled this rule in 2020-2021, as research showed that modern cars are already highly visible thanks to reflectors and bright colors. However, in Scandinavian countries, where daylight hours are short, the requirement was retained.
4. Which headlights are best to use during the day: comparison of options
Not all light sources are created equal for daytime riding. Let's look at the pros and cons of each option.
| Headlight type | Pros | Cons | Suitable for day driving? |
|---|---|---|---|
| Daytime running lights (DRL) | Low power consumption, bright directional light | They don’t illuminate the road and can dazzle if set incorrectly | ✅ Yes |
| Low beam (halogen/LED) | Versatile, illuminates the road at dusk | Increased energy consumption, lamps burn out faster | ✅ Yes |
| Fog lights | Clearly visible in fog and rain | May cause glare in clear weather, prohibited in some countries | ⚠️ Only if traffic rules allow |
| Side lights | Minimum power consumption | Low visibility during the day, does not comply with traffic regulations | ❌ No |
Optimal choice for most cars — DRL or low beam. If your car is not equipped with daytime running lights (e.g., older models like VAZ 2107 or Renault Logan first generation), you must use low beam.
Important: If you install LED or xenon lamps in headlights not designed for them, you risk a fine of up to 5,000 rubles for improper lighting devices (Part 3 of Article 12.5 of the Code of Administrative Offenses).
If your car does not have DRL, consider installing certified daytime running lights. For example, for Kia Rio or Lada Vesta, there are ready-made kits from Hella or Osram that are easy to connect to the onboard network.
5. How to properly adjust your headlights so as not to blind oncoming traffic
Even if you turn on your headlights during the day, improper adjustment can create dangers. Here’s what to pay attention to:
1. Light beam height
If the headlights are set too high, they will blind oncoming drivers even in daylight. Check the adjustment:
- 📏 The boundary of the light spot should be 1–1.5 meters in front of the car at a distance of 5 meters from the wall;
- 🔧 On most cars, adjustment is done with screws on the back of the headlight (see the manual for your model, e.g., Ford Focus or Skoda Octavia).
2. Cleanliness of headlights
Dirty or oxidized headlights reduce light output by 30–50%. Clean them at least once a month with a special polish (e.g., 3M Headlight Restoration Kit).
3. Matching lamps
Never mix different types of lamps in one headlight (e.g., halogen on one side and LED on the other). This creates uneven lighting and can confuse other drivers.
Load the car as usual (with a driver or passenger)|Park on a flat surface 5 meters from a wall|Measure the height of the headlights from the ground|Adjust the screws until the light spot matches the standards|Check the symmetry of the left and right headlights-->
⚠️ Attention: If you have adaptive headlights (e.g., on Audi A6 or BMW 5 Series), they automatically adjust the beam depending on the load and road conditions. However, even they require periodic calibration — at least once a year at a service center.
6. What happens if you ignore the rule: real cases and statistics
Many drivers believe that the fine for not using headlights during the day is "unfair" and can be avoided. However, there are more serious risks:
Case 1: Accident due to poor visibility
In 2022, in the Moscow Region, a Volkswagen Passat collided with a Kamaz truck at an intersection. The truck driver stated in court that he did not notice the car because its headlights were off, although it was a sunny day. The court ruled in favor of the truck driver, and the Passat owner had to pay for the repairs.
Case 2: Fine for tinted headlights
In St. Petersburg, a Toyota RAV4 driver was fined 3,000 rubles for using tinted headlights during the day. The inspector explained that the tint reduced visibility by 60%, making the car almost invisible in bright sunlight.
According to GIBDD statistics, in 2023, about 15% of daytime accidents involving pedestrians occurred due to poor vehicle visibility. In most cases, the drivers did not use headlights.
In Sweden, after the introduction of mandatory daytime running lights in 1977, the number of fatal accidents decreased by 11% in the first year alone.
7. Exceptions and special cases: when can you not turn on the headlights?
There are situations where the requirement to use headlights during the day does not apply or is impractical. Let's list them:
1. Parked car
If the car is parked (even with the engine running), headlights are not required. However, if you are in a dangerous parking (e.g., on the side of a highway), it is better to leave the hazard lights or side lights on.
2. Classic cars without electrical systems
Vehicles older than 1950 (e.g., GAZ-M20 Pobeda or ZIS-110) are often exempt from this rule, as they were not originally equipped with the necessary electrical systems. But you need to confirm this with the traffic police regulations in your region.
3. Motorcycles and mopeds
For two-wheeled vehicles, the rules are usually stricter: headlights must be on at all times, even when stationary. But in some countries (e.g., Italy), scooters under 50 cc are exempt.
4. Emergency vehicles
Ambulances, fire trucks, and police cars may turn off their headlights if they are using special signals (blue lights and sirens).
⚠️ Attention: If your car is equipped with automatic headlights (e.g., Mercedes-Benz with Intelligent Light System), make sure they are set to "Auto" mode. Some systems do not turn on the headlights during the day if the ambient light sensor considers it unnecessary — but this does not exempt you from responsibility under the traffic rules!
Even if your car has automatic headlights, manually check their operation in daylight — some systems prioritize energy saving over compliance with traffic rules.
FAQ: Frequently asked questions about daytime headlights
Do I need to turn on the headlights during the day if I have LED strips instead of DRL?
No. LED strips that are not certified as daytime running lights do not meet the requirements of the traffic rules. You risk a fine of 500 rubles for "non-use of headlights" and up to 3,000 rubles for "unauthorized changes to the design".
Can I use fog lights instead of low beam during the day?
Yes, but only if they are front fog lights and installed in accordance with GOST. Rear fog lights can only be used in poor visibility (fog, heavy rain, snow).
Why do some cars have their headlights on automatically, while others don't?
This depends on the lighting control system. For example:
- 🔧 Toyota Camry (from 2018) — headlights turn on automatically when the engine starts;
- 🔧 Lada Granta (basic version) — requires manual activation;
- 🔧 Volkswagen Tiguan — has a "Coming Home/Leaving Home" function that keeps the headlights on for a while after turning off the engine.
Check your car's manual under the section Lighting → Daytime Running Lights.
Is it true that daytime headlights increase fuel consumption?
Partially true, but the difference is negligible. For example, halogen headlights (2×55 W) increase fuel consumption by about 0.1–0.2 liters per 100 km. For LED headlights, this figure is 5–10 times lower.
What to do if the traffic police inspector claims that my DRL are not bright enough?
Request an instrumental check with a luxmeter. According to GOST R 41.48-2004, the brightness of DRL should be at least 400 candelas. If your headlights meet this standard, the fine can be appealed.
