When can a vehicle without daytime running lights use a width indicator?

At present, China's traffic safety law does not require that lights must be turned on during the day, but for vehicles without daytime running lights, attention should be paid to the use of lights when driving at ordinary times. It is suggested to turn on the width indicator or the low beam indicator according to the road conditions and weather conditions. Friends who are not used to turning on the low beam indicator should turn on at least one width indicator. Sometimes, from the driver's point of view, visibility and light are good and everything can be seen, but at this time, other vehicles may not be able to see you clearly. For example, if you drive in the sunset and follow the light, you can see clearly the situation ahead, but the car in front may be blurred because you can only see the sunset in his rearview mirror, while the car in front of you can see it in the rearview mirror. ? On the other hand, when vehicles pass under the overpass in the city, because the light under the bridge is much darker than outside, vehicles without lights are blurred and difficult to see clearly. Even vehicles with automatic headlights will only light up briefly after entering the bridge. If they merge at the moment they enter the bridge, they are likely to ignore the vehicles without any lights behind them. Like Beijing, which is often shrouded in smog in recent years, it is even more necessary to use the function of daytime running lights. When the smog is serious and it is not clear 200 meters away, the effect of turning on the light is very different!

Generally speaking, if there are no daytime running lights, for the safety of yourself and others, try to turn on the width indicator to remind the surrounding vehicles on special sections.
