Planning a trip before starting it is a **preventive road safety behavior** for several reasons:

- **Choosing the right route**: Before starting the trip, it is important to plan the route using a map. This allows you to select the safest and most comfortable path, considering factors such as roadworks, weather, and traffic volume. This planning helps avoid dangerous situations and reduces the risk of accidents.

- **Scheduling breaks**: Planning breaks during the trip is essential to avoid driver fatigue, which is a common cause of accidents. Proper rest improves concentration and the ability to react to unforeseen events.

- **Preparation for adverse conditions**: In winter, it is crucial to carry chains, avoid driving at night, and keep the fuel tank full. Additionally, carrying warm clothing, water, food, and a flashlight in the vehicle can be vital in case of emergencies.

- **Safety checks**: Before leaving, it is necessary to verify that the vehicle is equipped with safety elements such as emergency triangles, a reflective vest, a spare wheel, and preferably, a first aid kit. These elements are essential for handling emergency situations on the road.

- **Defensive driving**: This way of driving involves anticipating unforeseen events and adapting to the circumstances of the trip. Gathering information before leaving and being prepared to react appropriately to unexpected situations are key aspects of road safety.

In summary, planning a trip properly is a preventive measure that significantly contributes to road safety, as it allows you to anticipate potential problems and be better prepared to face them.
