As the data is updated on this site there will be instances of adding new incidents and updating existing data with information gathered through the investigative process.,Not surprisingly, crash data becomes more accurate over time, as new crashes are reported and more information comes to light during investigations.,This dynamic nature of crash data means that content provided here today will probably differ from content provided a week from now. Likewise, content provided on this site will probably differ somewhat from crime statistics published elsewhere by the Town of Cary, even though they draw from the same database.,,About Crash Locations,Crash locations reflect the approximate locations of the crash. Certain crashes may not appear on maps if there is insufficient detail to establish a specific, mappable location.,This dataset is updated daily.,
