Office of Highway Safety

HS investigates those accidents that have a significant impact on the public's confidence in highway transportation safety, generate high public interest and media attention, or highlight national safety issues. HS staff investigates accidents involving issues with wide-ranging safety significance, such as collapses of highway bridge structures, fatalities on public transportation vehicles (such as buses and vans), collisions at highway/rail grade crossings and selected accidents that involve new safety issues/technologies. In addition to these more catastrophic accident events, HS also conducts studies based on trends emerging from NTSB accident investigations and from other research and accident data to identify common risks or underlying causes of accidents. The NTSB is the only organization that performs independent, comprehensive, and transparent, multidisciplinary investigations to determine the probable cause of a highway accident with the goal of making recommendations that will prevent similar accidents in the future.

The Investigations Division

The Investigations Division manages the multidisciplinary go-teams that are launched to accident sites and are responsible for collecting the factual and analytical information for investigations. Each team is led by an investigator-in-charge (IIC) and includes five other investigators with expertise in vehicle, highway, human performance, survival, and motor carrier factors. To enhance geographic coverage and reduce response time, team members are located throughout the country, including Massachusetts, Delaware, Texas, Colorado, California, and Washington, DC.

The Report Development Division

The Report Development Division is responsible for researching and developing national highway safety issues, managing the development and preparation of the final accident reports, coordinating the presentation of these reports at a public Board meeting, and issuing safety recommendations. The Division is also responsible for managing Safety Hearings related to ongoing accident investigations and public/forums or other venues designed to make the public more aware of safety issues. The staff of this division also writes the majority of the highway related speeches and Congressional testimony for the office and for Board Members.
