The **majority of traffic accidents** are related to the **human factor**. This is because between **70 and 90 out of every 100 accidents** are caused by driver errors or inappropriate behaviors. Some examples of these behaviors include **speeding**, **alcohol consumption**, and **distractions** while driving.

Distractions are especially common in certain groups of drivers, such as **young people between 18 and 25 years old** and **those over 70 years old**. They are also more frequent when there are **several people in the vehicle** and during the **summer months**.

In comparison, accidents caused by the **condition of the road** or **vehicle failures** are less common. For example, road problems, such as being wet or losing control on a curve, cause between **10 and 35 out of every 100 accidents**. Mechanical failures, such as problems with brakes or tires, are responsible for between **4 and 13 out of every 100 accidents**.

Therefore, the **human factor** is the main cause of traffic accidents, and many of these can be avoided with responsible behavior on the part of the driver.
