Driving at **high speed** increases the **severity of injuries** in the event of an accident. This is because, at higher speeds, the impact is stronger, which increases the risk of severe injuries or even death.

- **Speed limits**: They are designed to ensure safety. For example, in urban areas, it is recommended to drive at less than 50 km/h to reduce the severity of accidents. On roads and highways, the limits are higher, but always with the aim of minimizing damage in the event of a collision.

- **Vision and reaction**: At high speeds, reaction capacity decreases and the **tunnel vision** effect is experienced, meaning the driver only sees what is directly in front, increasing the risk of serious accidents.

- **Road conditions**: Speed limits also consider the type of road and its conditions to ensure that, in the event of an accident, the consequences are not as severe.

In summary, respecting speed limits is crucial to reducing the severity of injuries in accidents.
