Slow Down, Move Over Laws: National Survey of Drivers’ Knowledge, Attitudes, and Behaviors, 2025
More than 2,100 people were struck and killed while stranded or working on the roadside in 2019–2023. Included among them were drivers and passengers who exited disabled vehicles, as well as roadside assistance providers, law enforcement officers, firefighters, emergency medical services providers, and “Good Samaritans” attempting to help them. Slow Down, Move Over (SDMO) laws […]
Strategies to Improve Reporting of Impaired and Distracted Driving in Motor Vehicle Crashes 2026
Crash reports are the primary source of data for identifying crash types, involved persons and vehicles, contributing factors, and crash patterns and trends. Researchers and policy makers depend on crash report data to identify problems, select and evaluate countermeasures, and analyze the effectiveness of safety measures and policies designed to reduce motor vehicle crash frequency […]
The Impact of Dynamic Prices on Electric Vehicle Public Charging Demand
Understanding how to effectively influence electric vehicle (EV) charging behavior is critical for managing electricity grids powered by high levels of variable renewable generation. We present results from a large-scale natural field experiment conducted in the United Kingdom, involving approximately 110,000 EV customers and 60% of the country’s public charging infrastructure. Within this network, we […]
Wintertime Pavement Maintenance Practices
State transportation agencies have many tools available with which to maintain pavements proactively. These include tools such as pavement management systems to track roadway conditions and life cycle cost analysis tools. NCHRP Synthesis 623: Wintertime Pavement Maintenance Practices, from TRB’s National Cooperative Highway Research Program, documents the current state DOT practices for the reactive pavement […]
Identifying Outcome Measures to Evaluate Drivers’ Knowledge of Vehicle Automation
Advanced vehicle technologies have the potential to improve safety and convenience for drivers; however, to realize these benefits, it is important that drivers use the systems appropriately. Past research has documented gaps in drivers’ understanding of how new technology works and when it should be used. It follows that the interplay between a driver’s knowledge, […]

Traffic Safety Facts: Alcohol-Impaired Driving
Drivers are considered to be alcohol-impaired when their blood alcohol concentrations (BACs) are .08 grams per deciliter (g/dL) or higher. Thus, any fatal crash involving a driver with a BAC of .08 g/dL or higher is considered to be an alcohol-impaired-driving crash, and fatalities occurring in those crashes are considered to be alcohol-impaired-driving fatalities. The […]
