Summary

**Research Problem and Motivation** This report presents the final findings of a multidisciplinary study conducted by the Maryland Medical-Legal Foundation, sponsored by the National Highway Traffic Safety Administration (NHTSA). The primary objective was to conduct in-depth investigations of vehicular accidents to identify human, mechanical, and environmental causative factors. Specifically, the study aimed to evaluate occupant injury patterns relative to vehicle design, assess the effectiveness of current Federal Motor Vehicle and Highway Safety Standards, and analyze the role of alcohol and psychosocial factors in accident causation. The research sought to provide data that could inform traffic safety prevention strategies and reduce morbidity and mortality. **Methods and Experimental Design** The study employed a matched, two-group design investigating 50 accidents (25 fatal and 25 non-fatal) occurring in the Greater Baltimore metropolitan area between June 28, 1974, and June 30, 1975. Non-fatal cases were selectively matched to fatal cases based on time, day, culpability, alcohol involvement, and collision type. The multidisciplinary team utilized vehicle and scene examinations, autopsy findings, toxicological analysis (including blood alcohol and drug screening), and psychosocial evaluations. Psychosocial data were collected using the Katz Adjustment Scale and structured clinical interviews with drivers or their families. Additionally, the report incorporates compiled data from a three-year period (1972–1975) totaling 84 fatal and 71 non-fatal collisions to evaluate broader trends and federal safety standards. **Main Findings** The investigation revealed that alcohol consumption was a primary causative factor in 44% of fatal accidents, with 56% of culpable drivers in fatal crashes having consumed alcohol (mean blood alcohol level of .16%). Decision errors accounted for 20% of fatal accidents, while perception and decision/action errors were the most frequent factors in non-fatal crashes. A critical finding regarding safety equipment was that no fatally injured drivers or passengers in the 25 fatal cases utilized restraints, despite their availability in nearly all vehicles. The study concluded that proper restraint use would have saved the lives of at least 14 drivers and three passengers. Injury patterns indicated that the head, chest, and abdomen were the most severely affected areas, with steering mechanisms and instrument panels being primary impact points. Furthermore, psychosocial analysis suggested that responsible male drivers involved in fatal crashes exhibited a syndrome of deviant behaviors, including higher incidences of alcohol-related problems, compared to the general driving population. **Significance and Conclusions** The study concluded that Federal Highway Safety Standards regarding alcohol, highway design, and driver licensing were often non-performing or negatively cited, while Federal Motor Vehicle Safety Standards for occupant crash protection failed primarily due to non-use of restraints. The authors recommended two primary interventions: designing automobiles with sufficient safety features to preclude serious injury and enforcing traffic regulations with increased surveillance of high-risk drivers. The findings underscored that while alcohol abuse is strongly associated with serious accidents, it is part of a broader behavioral syndrome. The report emphasized that the severity of injury (fatal vs. non-fatal) was largely determined by circumstance and restraint use rather than distinct personal characteristics of the driver.

Key finding

Alcohol was a primary causative factor in 44% of fatal accidents and 28% of non-fatal accidents, while zero percent of fatally injured occupants utilized available restraint systems.
