The increasing presence of Advanced Driver Assistance Systems (ADAS) in modern vehicles underscores the need to assess user acceptance, which is essential for the effective integration of these technologies. This study introduces and validates the ADAS Acceptance Test (ADASAT), a novel questionnaire grounded in the Technology Acceptance Model (TAM). A sample of 347 Italian drivers completed the instrument, which evaluates four TAM constructs: Perceived Usefulness, Perceived Ease of Use, Attitude Toward Use, and Behavioral Intention. Exploratory and confirmatory factor analyses confirmed the theoretical four-factor structure, and the model demonstrated excellent internal consistency, convergent, and discriminant validity. Path analysis supported all hypothesized relationships among TAM constructs. The results confirm TAM’s applicability to the ADAS context and highlight the role of perceived usefulness and ease of use in influencing user attitudes and intentions. The ADASAT offers a valid psychometric tool to support research and policies supporting safe, user-centered technology adoption.
