What risk factors directly affect the driver?

Risk factors are situations that increase the probability of having an accident. In traffic accidents there are three factors and not all of them have the same impact: - Human factor (70% - 90%): by avoiding the risk factors that depend on the driver (distractions, speed, fatigue, alcohol, drugs, medication, etc.) the risk of having an accident and avoiding its serious consequences can be reduced. - Road and environment factor (10% - 35%): this occurs when we do not adapt our driving style to the road or weather conditions. - Vehicle factor (4% - 13%): this can be avoided by properly maintaining the vehicle.
