Summary

This 1975 interim report, prepared for the National Highway Traffic Safety Administration, reviews existing literature to determine the extent and causal role of alcohol in pedestrian collisions resulting in death or injury. The study was motivated by the high volume of pedestrian casualties—10,700 fatalities and 120,000 injuries in the United States in 1972—and a critical lack of definitive data regarding alcohol’s contribution to these events. The primary objectives were to ascertain whether alcohol is overrepresented in pedestrian accidents, quantify that overinvolvement, and identify behavioral differences associated with various blood alcohol concentrations (BAC). The authors analyzed three categories of available data: post-mortem BAC measurements from fatal crashes, controlled studies comparing victims to site-matched controls, and qualitative assessments of crash dynamics. The review examined ten major studies of fatally injured pedestrians and re-analyzed data from the Snyder and Knoblauch study, which covered over 2,000 pedestrian accidents in 13 U.S. cities. The authors critically evaluated the validity of these datasets, noting significant methodological flaws in existing fatality data, such as selection biases where BAC tests were routinely omitted for victims under 14 or those who survived more than six hours post-crash. The findings indicate that current knowledge of the pedestrian-alcohol problem is exceedingly limited and often biased. Post-mortem data showed a wide variance in alcohol involvement among tested victims, ranging from 30% to 74%, with a mean of approximately 45%. The authors argue that these figures likely overstate alcohol’s role because they exclude non-tested groups, such as children and older adults who survive longer, who have lower rates of alcohol consumption. The only controlled study reviewed, by Haddon et al., suggested a strong link between alcohol and fatal crashes but was deemed statistically unreliable due to a small sample size and anomalous survival rates. Re-analysis of the Snyder and Knoblauch data provided the most insight into non-fatal crashes, revealing that drinking pedestrians were overrepresented in "dart and dash" accidents, committed more behavioral errors than drivers, and were predominantly adult males aged 25–64. Alcohol involvement also correlated with increased injury severity and occurred more frequently at night and on weekends. The report concludes that virtually nothing is definitively known about the causal role of alcohol in pedestrian safety. Existing data are insufficient to quantify the problem or devise effective countermeasures. The authors emphasize that current fatality statistics overemphasize alcohol’s role due to sampling biases and that sober pedestrians also commit significant behavioral errors leading to death. They call for a carefully controlled epidemiological study involving both fatal and non-fatal crashes, with appropriate control groups, to accurately determine alcohol’s causal impact and inform future safety interventions.

Key finding

Drinking adult pedestrians appear overrepresented in dart and dash accident types and exhibit a higher proportion of behavioral errors compared to driver errors.
