Active and passive safety
Explanation
The **safety of a car** depends on two types of systems: **active safety** and **passive safety**.
- **Active safety**: These are the elements that help prevent accidents. A key example is the **tires**. They must be in good condition, without deformations or cracks, and with an adequate tread to ensure good grip and eliminate water in rainy conditions. This reduces the risk of accidents by improving the vehicle's stability and control.

- **Passive safety**: These elements minimize damage in the event of an accident. They work automatically, and common examples include the **seat belt**, the **airbag**, and the **headrest**. These devices protect the vehicle's occupants by reducing the impact of a collision.

Therefore, the safety of a car does not depend solely on a single element, such as airbags or the bodywork, but on the combination of these active and passive safety systems that work together to prevent accidents and protect the occupants.
