Summary
This study addresses the persistent safety risks faced by emergency responders and roadside workers, motivated by the 46 fatalities among these individuals in 2024. Although "Slow Down, Move Over" laws are enacted in all 50 states and Washington, D.C., compliance remains inconsistent. The research aims to investigate factors influencing driver behavior and compliance to identify strategies for improving safety. The researchers employed a mixed-methods approach comprising three phases. First, they documented state laws and surveyed stakeholders from highway safety offices, departments of transportation, and law enforcement to assess education and enforcement efforts. Second, they conducted focus groups with 135 drivers across 10 states to gather qualitative insights on driver perceptions and behaviors. Third, they analyzed real-world behavior using video footage from traffic cameras in 13 states, observing 12,365 drivers passing 169 unique incident scenes to quantify compliance rates and identify influencing factors. Key findings revealed substantial variability in state laws regarding protected vehicles, required actions, and penalties. Focus groups indicated that while most drivers reported complying, they often prioritized moving over over slowing down and were frequently unaware of specific legal requirements or protected vehicle types. Drivers cited limited enforcement and low visibility of outreach as barriers. Observational data showed moderate overall compliance: 64% of vehicles changed lanes or reduced speed, while 36% did neither. Notably, lane changes were far more common than speed reductions; in states requiring specific speed drops, very few drivers complied. A significant gap existed between self-reported intent and observed behavior, particularly regarding speed reduction. The study attributes this inconsistency to poor public awareness of law details, ambiguous legal language, and a perceived low risk of enforcement. The authors conclude that an integrated approach is necessary to enhance compliance. They recommend standardizing legislation to protect all roadside personnel with simplified, consistent language and impactful penalties. For public education, they advocate for emotionally compelling, visually clear public service announcements distributed across multimodal channels, including digital platforms and roadway signage. Regarding enforcement, they suggest high-visibility campaigns, using routine stops for education, and exploring automated enforcement technologies with a focus on transparency and education. Implementing these strategies across legislative, educational, and enforcement domains is expected to significantly improve driver awareness and create safer roadside environments.
Key finding
Observational data showed that 64% of drivers complied with Slow Down, Move Over laws by changing lanes or reducing speed, but lane changes were significantly more common than speed reductions, revealing a gap between self-reported compliance and actual behavior.
