The **majority of traffic accidents** are due to the **human factor**. This means that the actions or decisions of people behind the wheel are the main cause of accidents. Examples of these factors include **speeding**, **consuming alcohol**, and **distractions** while driving. These behaviors are responsible for between **70 and 90 out of every 100 accidents**.

On the other hand, other factors such as the **condition of the road** and **vehicle failures** can also cause accidents, but to a lesser extent. Wet roads or losing control on a curve contribute to between **10 and 35 out of every 100 accidents**, while mechanical problems such as brake failures or a flat tire are responsible for between **4 and 13 out of every 100 accidents**.

Therefore, although all these factors can influence the occurrence of an accident, the **human factor** is the most significant and, therefore, the most important to consider in order to prevent accidents.
