Modern psychometric assessment tools that measure the level of anxiety and stress in drivers, whether temporary and related to a specific traffic situation (situational anxiety) or permanent and stable, as a common personality trait (chronic or personal anxiety). The most well-known of these tests is the STAI (Anxiety Condition and Personality Trait Questionnaire), which allows you to distinguish between the immediate effects of stressful situations and personality traits associated with persistent anxiety. These tests aim to determine a driver’s ability to cope with stressful situations and emergencies while driving, including stress arising from traffic jams, accidents, or interactions with unexpected behaviors of other drivers and pedestrians. They also aim to understand the relationship between anxiety levels and decision-making, as high anxiety or stress can lead to impaired attention, slower reactions, hasty or rash decisions, and an increased likelihood of traffic accidents. The practical application of these tests is to develop driver education and awareness programs to help improve the ability to cope with stress and anxiety and develop coping strategies while driving. They are also used in traffic research to study the relationship between psychological stress, work efficiency, and decision-making on the road. This allows for the development of preventive measures and educational strategies aimed at reducing the risks associated with psychological stress. As such, anxiety and stress tests are critical tools for understanding the impact of emotions on road safety, improving driver performance, and preventing risky behaviors caused by excessive stress or anxiety while driving.
