To drive safely, it is important to know when to use **low beam headlights**. These lights are mandatory in certain situations to improve visibility and road safety.

- **Reversible lanes**: During the day, it is mandatory to turn on low beam headlights when driving in a **reversible lane**. A reversible lane is one that can change direction according to traffic needs. This means that sometimes it is open in one direction and other times in the opposite direction. Using lights in these lanes helps other drivers see you better and prevents accidents.


- **Other situations**: In addition to reversible lanes, low beam headlights must also be used during the day in tunnels and in additional or provisional lanes created by construction or accidents. These lights are essential to ensure that your vehicle is visible to other drivers in low visibility conditions.

In summary, whenever you drive in a reversible lane during the day, make sure to have your low beam headlights on to comply with traffic regulations and ensure road safety.
