Scared? Actually not so scary. Let's find out when and in what cases it is necessary to include headlights, fog lights, main beam or dipped beam and dimensions. Data is valid on 24 November 2016.

For convenience, we describe the rules of use car light depending on the time of day and other conditions, and answer some pressing questions. And at the end of this article we present the table as a simple method to remember when which lighting devices must be enabled on the machine.

What kind of light to use during the day?

Day, namely, in the daytime, we can use the daytime running lamps (19.5 SDA). But instead of DRL (not only if they are not installed in the car, but at the request of the driver), you can use dipped headlights or fog lights (19.4 + 19.5 SDA).

In the daytime (provided that no conditions of insufficient visibility) you need to include:

  • daytime running lights;

  • dipped beam;

  • fog lights (but not together with dipped beam or DRL).

In the daytime you cannot include:

  • main beam;

  • the rear fog lights.

What kind of light to use in the dark?

Night in the SDA is defined as "the period of time from the end of evening twilight to beginning of morning twilight" (SDA 1.2). Thus, in the dark part completely night, night from the end of morning twilight and before the beginning of dawn.

In the dark you need to include:

  • low or high beam headlamps in traffic (see below under what conditions you cannot use high beam);

  • Parking lights when you stop or Park on the road and on trailers and towed vehicles;

  • fog lights — only on unlit roads and only in conjunction with near or far light of headlights.

Also in dark you can enable with a special spotlight the spotlight under the condition of movement outside the settlement and in the absence of oncoming cars.

In the dark is forbidden to use:

  • main beam headlights:

- in the settlements, if the road is lit,

— if oncoming traffic closer than 150 meters to You or even if on and blinking You lights,

— in all other cases when it is possible to blind the drivers (just drivers, not pedestrians) and counter-passing machines;

  • fog lamps — lit or unlit roads without near or far light of headlight;

  • daytime running lights;

  • the rear fog lights.

What kind of light to use in conditions of poor visibility (in fog)?

The conditions of insufficient visibility, as defined in the Rules, so no confusion there. These conditions include the visibility of the driver is less than 300 metres in fog, at dusk, in rain, snow and the like. In General, if visibility of the road is approximately 300 m or more, the only case when at the moment of the night, it is the conditions of insufficient visibility.

In the conditions of insufficient visibility should include:

  • low or high beam headlamps in traffic (see above in the description of the lighting in the dark conditions in which you cannot use the high beam);

  • Parking lights when you stop and Park - low beam headlight, fog light or rear fog lamps together with the Parking lights can also be included in the conditions of insufficient visibility (in contrast to the dark time of day).

  • fog lights — only in conjunction with near or far light of headlights (and on the roads any light, unlike the dark time of day).

  • rear fog lights (this is the only condition in which to use them).

In conditions of poor visibility do not use:

  • fog lights without the dipped or main beam;

  • daytime running lights.

What kind of light to use in the tunnel?

Traffic reglementary the necessity of inclusion of headlights in tunnels (item 19.1). The rule here is simple: the conditions of the use of certain light devices are the same as in the dark.

When can we use "hazard"?

Alarm is also considered a light device, and the SDA clearly reglementary the possibility of their use. Thus, the "emergency gang" need to include:

  • in case of an accident together with the sign of emergency stop (2.5 SDA + SDA 7.1);

  • if you encounter a situation when Your vehicle is dangerous;

  • emergency stop in the place where stop Smoking (together with the sign of emergency stop);

  • when towing a towed vehicle;

  • if You are blinding oncoming traffic.

When blinking headlights?

Yes, most drivers blink lights (one or more momentary switches headlight with DRL near or far) when warning of the traffic police, oncoming cars. However, the SDA is recommended to do it completely in other cases. What:

  • for warning other traffic participants about the beginning of the overtaking;

  • if You dazzle an oncoming vehicle.

At the same time, nowhere in the Rules do not specify a direct ban blinking headlights. However, by the DPS, this can be regarded as a traffic violation, as a result you can easily earn a fine of 500 rubles. Think about it, because if you blink You turn on the headlights, and to turn it on in most cases prohibited.

As you can see, it's very simple! But let's further simplify these Rules for the use of lighting devices and present everything in a clear tabular form.
