Sharing Crash Data and Protecting Personal Identifying Information


The Wisconsin Department of Transportation (WisDOT) conducted a RAC survey on ‘Sharing Crash data with the Public,’ in 2007. It provided some very valuable information. The protection of personal information contained in the crash reports is very important to all the states. Following up on the WisDOT survey, the Connecticut Department of Transportation (CTDOT) is interested in learning about how states handle and protect personal information when receiving or fulfilling a crash data request.

The following questions were asked as part of this survey:

1. How does your state receive crash data from state and local police agencies? If electronic, how is the data transferred? FTP? Cloud? Hard drive? Other?

2. When data is provided from the police agencies to the state DOT, does it include personal information such as name(s), address, date of birth, driver’s license number etc.; or, is the personal information redacted before sharing?

3. Where does the data reside, at the DOT or somewhere else? If somewhere else, is the data linked or shared in some way with the DOT?

4. Do you provide public access to your crash data? If so,

a. What information is provided?

b. Do you provide any personal information?

c. If you don’t generally provide personal information, do you make such information available if requested under Freedom of Information (FOI) (assuming the personal information is provided by the police agencies in the crash reports shared with the state DOT) or do you refer them to the respective police agency to obtain the information?

5. If you do not provide public access to your crash data, how do you fulfill requests for crash data?

6. Can we follow up with any additional questions? If so, please provide contact information.
