Summary

This report by the National Highway Traffic Safety Administration (NHTSA) examines disparities in seat belt use and related attitudes across different racial and Hispanic origin groups in the United States. The study addresses the significant variation in unrestrained fatalities among these groups, aiming to identify whether behavioral differences or enforcement perceptions contribute to these disparities. The analysis integrates data from three primary sources: the Fatality Analysis Reporting System (FARS) for 2018, the National Occupant Protection Use Survey (NOPUS) for 2019, and the Motor Vehicle Occupant Safety Survey (MVOSS) conducted in 2016–2017. The methodology combines observational, self-reported, and fatality data. FARS data revealed that among fatally injured passenger vehicle occupants with known restraint status, unrestrained rates varied significantly by race and ethnicity. For instance, 68% of Native Hawaiian or Other Pacific Islander fatalities and 67% of American Indian fatalities were unrestrained, compared to 45% of White and 47% of Hispanic fatalities. NOPUS provided observed seat belt usage rates, showing lower front-seat use among Black occupants (86.4%) compared to White (90.7%) and other races (94.1%), with even larger gaps in rear-seat usage. MVOSS, a nationally representative survey of 6,009 respondents, collected self-reported seat belt habits and attitudes toward enforcement and safety beliefs, categorized by OMB race and ethnicity guidelines. Key findings indicate that while self-reported seat belt use was generally similar across groups, significant differences existed in attitudes and perceived enforcement risks. Support for primary seat belt enforcement laws was highest among Asian (89%) and Hispanic (82%) drivers, but lower among Black (77%), Multiracial (69%), and White (76%) drivers. Crucially, perceptions of citation likelihood differed markedly: 41% to 49% of Asian, Black, Hispanic, and Multiracial drivers believed they were "very likely" to receive a ticket for non-use, whereas only 25% of White drivers held this belief. Additionally, unfavorable beliefs about seat belts, such as the view that they are as likely to harm as help or that fatalism negates their utility, were more prevalent among Black, Hispanic, and Multiracial drivers than among Asian or White drivers. The significance of these findings lies in the implication for targeted safety countermeasures. The report concludes that high-visibility enforcement strategies, which rely on increasing the perceived risk of citation, are unlikely to be effective for many non-White drivers who already perceive a high likelihood of being ticketed. Instead, the authors suggest that non-enforcement countermeasures addressing unfavorable beliefs and social norms regarding seat belt use may be more effective for increasing compliance among Black, Hispanic, and Multiracial populations. This highlights the need for race- and ethnicity-specific approaches in traffic safety interventions.

Key finding

Unrestrained fatalities were disproportionately higher among American Indian, Native Hawaiian, Black, and multiracial occupants, and non-White drivers exhibited more fatalistic beliefs about seat belts and higher perceived ticket likelihood than White drivers.
