**Inadequate or excessive speed** is one of the main causes of traffic accidents. This occurs when driving at a speed that, although within legal limits, is not suitable for the current conditions, such as weather, road conditions, or vehicle circumstances. For example, driving at 70 km/h on an icy road can be dangerous.

In terms of statistics, **human factors**, such as speeding, are responsible for between **70 and 90 out of every 100 accidents**. This indicates that approximately one-third of accidents with victims are related to inadequate or excessive speed. Therefore, it is crucial to adjust speed to the surrounding conditions to avoid accidents.
