Summary
This study investigates the paradoxical rise in U.S. traffic fatalities during the COVID-19 pandemic, which occurred despite a significant reduction in total miles driven. While aggregate travel decreased by approximately 20–26% in 2020, crash rates and fatalities increased, particularly those involving speeding, impairment, and seatbelt non-use. The research aims to determine whether changes in the composition of drivers on the road—specifically shifts in who was driving and how much—contributed to this negative safety outcome. The authors analyzed data from the AAA Foundation’s 2020 Traffic Safety Culture Index survey, conducted between October and November 2020. The sample consisted of 2,888 licensed active drivers aged 16 and older. Respondents were categorized based on whether they reported reducing, maintaining, or increasing their driving frequency due to the pandemic. The study examined self-reported engagement in various risky behaviors over the prior 30 days, including distracted driving (cellphone use, texting), speeding, aggressive lane changes, running red lights, drowsy driving, unbelted driving, and substance-impaired driving (alcohol and marijuana). Using Poisson regression, the researchers calculated adjusted prevalence ratios for these behaviors, controlling for demographic factors (age, sex, education, race/ethnicity) and driving frequency. The results indicated that 60% of drivers reduced their driving, 36% maintained their levels, and only 4% increased their driving. Those who increased their driving were significantly younger (median age 39) and more likely to be male compared to other groups. Crucially, drivers who increased their driving exhibited substantially higher rates of risky behaviors. After adjusting for demographics and driving frequency, this group was 40% more likely to speed, 67% more likely to run red lights, 86% more likely to change lanes aggressively, more than twice as likely to drive while alcohol-impaired, and nearly three times as likely to drive after using marijuana. Conversely, drivers who reduced their driving were 33% less likely to drive without a seatbelt. These associations persisted even when accounting for the fact that the "increased driving" group drove more days per week. The study concludes that the increase in traffic fatalities during the pandemic may be partially attributable to a shift in the driving population toward higher-risk individuals. The drivers who continued or increased their travel were disproportionately young males with a higher baseline propensity for risky behaviors. Meanwhile, the reduction in driving was led by middle-aged females, a statistically safer demographic. This compositional shift likely increased the overall risk per mile driven. The authors suggest that underlying risk-taking tendencies, risk homeostasis due to lighter traffic, or pandemic-related stress may explain these behavioral patterns, highlighting that aggregate travel metrics alone do not capture the nuanced changes in driver safety profiles.
Key finding
Drivers who increased their driving during the pandemic were significantly more likely to engage in a wide array of risky behaviors, including distracted driving, speeding, and impaired driving, compared to drivers who maintained or reduced their driving.
