Crash and injury data was collected from July 1, 2008 to June 30, 2009.
The Tribune built this application using records submitted by cities to the Texas Department of Transportation. Some cities didn't complete all fields in the forms. Rendering maps using this type of government data can be tricky, especially given the fact that street names vary. We've tried to make sure the intersections, data and images are accurate, but please let us know if you spot errors or have questions.Term Definitions
