Summary
This research brief reviews the scientific literature on the effectiveness of countermeasures against distracted driving, motivated by the high prevalence of the behavior and its associated crash risks. With 3,166 fatalities reported in 2017 in the U.S. involving distracted drivers, and survey data indicating widespread engagement in handheld phone use and texting, the authors sought to evaluate existing interventions to guide resource allocation. The study conducted a systematic search of five databases (PubMed, TRID, PsycARTICLES, PsycINFO, and PsycEXTRA) for English-language articles published between 2010 and 2019. From an initial pool of 15,000 articles, reviewers identified 102 relevant studies assessing the impact of educational, legislative, enforcement, and technological countermeasures on crash data, observed behavior, self-reported behavior, or driving performance. The review categorized findings into four main types. Educational and behavioral countermeasures, such as awareness campaigns and training programs, yielded mixed results. Multifaceted campaigns in hospitals and schools often produced short-term reductions in distracted driving, though some effects did not persist long-term. Single-event educational interventions generally improved attitudes and behavioral intentions but rarely demonstrated changes in actual on-road behavior. Legislative countermeasures showed varied efficacy. All-driver handheld cellphone bans were associated with reductions in self-reported and observed phone use, as well as some decreases in fatal and injury crashes, though some studies found no effect or increases in hands-free usage. All-driver texting bans produced conflicting results, with some studies noting reductions in crashes and hospitalizations while others found no impact or increased collision claims. Primary bans were generally more effective than secondary bans. Complete cellphone bans for teen drivers showed limited effectiveness, with mixed results regarding traffic fatalities and no significant impact on fatal crashes involving drivers under 21. Enforcement and technology countermeasures were less extensively studied. High-visibility enforcement of bans reduced observed handheld phone use but had no significant effect on crashes or collision claims. Technology-based solutions, particularly phone-blocking apps, demonstrated promise in reducing phone interactions, though compliance issues and reliability concerns remain. Driver monitoring and feedback systems showed mixed efficacy, with challenges in sustaining user engagement. The authors conclude that while the body of literature is modest, no single countermeasure is universally effective. Educational interventions often fail to translate into sustained behavioral change, and legislative bans show inconsistent impacts on crash outcomes. The review highlights the need for rigorous, long-term evaluations of countermeasures, particularly regarding their scalability and interaction effects. It suggests that a systems-based approach, potentially combining multiple countermeasure types, may be necessary to effectively mitigate distracted driving, as current evidence indicates that isolated interventions have limited and variable success.
Key finding
Across roughly 100 studies, all-driver handheld cellphone bans most often reduced handheld phone use but crash outcomes were inconsistent, while all-driver texting-ban evaluations were evenly split between reductions and null or increased crash measures.
