Special Investigation Report: Wrong-Way Driving

This special investigation report looks at one of the most serious types of accidents that occur on our highways: collisions involving vehicles traveling the wrong way on high-speed divided highways. The goal of the project is to identify relevant safety recommendations to prevent wrong-way collisions on such highways and access ramps. The investigations included in the report take a focused view of the driver and highway issues affecting wrong-way collisions.

The report will discuss the following areas:

  • Wrong-way collisions - Defines the problem, examines the NTSB history with these types of collisions, and surveys the data and research concerning wrong-way driving collisions.
  • NTSB investigations - Summarizes nine NTSB wrong-way collision investigations.
  • Characterization of wrong-way driving - Considers the components of wrong-way collisions and uses data, research, and NTSB investigative work to summarize these types of collisions.
  • Countermeasures - Provides recommendations to address wrong-way collisions.


NTSB public events are also streamed live via webcast. Webcasts are archived for a period of three months from the time of the meeting. Webcast archives are generally available by the end of the event day for public Meetings, and by the end of the next day for Technical conferences.
