A specialized psychometric tool designed to measure the psychological and emotional functions of drivers in relation to their ability to manage their emotions and regulate their emotional reactions while driving, especially in stressful or tense situations. This type of test focuses on assessing a driver’s ability to recognize emotional states such as anger, anxiety, frustration, and stress, as well as their ability to regulate these emotions and control their impulses to reduce risky or aggressive behavior on the road. These tests usually include a set of measurements that reflect anger control, as road rage is a major cause of aggressive behavior and accidents. Stress tolerance measures a driver’s willingness to cope with the pressures that arise from traffic jams, tardiness or annoying behaviour from others. Impulse monitoring measures a driver’s propensity to make rash decisions, such as overtaking or speeding unsafely, without an adequate risk assessment. The main application of these tests is to predict risky behaviour on the road, such as the likelihood of aggression towards other road users or exaggerated reactions in emergency situations that can increase the severity of the consequences of accidents. They are also used in driver education and psychological rehabilitation programs to develop self-control skills, and are also included in the development of prevention and rehabilitation programs aimed at groups more susceptible to stress or excessive emotionality. In addition, these tests are important tools in scientific research examining the relationship between emotional traits and ability to drive safely, contributing to the development of more effective road policies based on a thorough understanding of the psychological factors that influence road user behavior.
