Before opening the doors of a vehicle to exit, it is essential to ensure **not to endanger other road users**. This includes both pedestrians and other vehicles.

- **Observe the road**: Before performing any maneuver, such as opening a door, it is crucial to carefully observe the traffic and the road. This is done by looking directly and using the rearview mirrors to ensure there is no danger.

- **Blind spots**: Although the mirrors help to see what is happening behind and to the sides of the vehicle, there are always areas called **blind spots** that cannot be seen. It is important to turn your head and look through the window to ensure there are no pedestrians or other vehicles in these areas before opening the door.

- **Signal the maneuver**: If necessary, you should inform other road users of the intention to open the door, either with hand signals or with the vehicle's lights, to avoid surprises and accidents.

In summary, the safety of all road users should be the priority when opening the doors of a vehicle.
