The Decoded Diagram Detail Report contains detailed collision history information for a specific state route location or roadway section. Instead of displaying the alphanumeric codes as with the Standard Diagram Detail Report, the Decoded Diagram Detail Report contains a description for each code, making it easier to interpret the movements and actions of the vehicles involved in the collisions. As a result of the lengthy descriptions, there is less other available report information.
Below is a sample of a Decoded Diagram Detail Report and the information it would contain. To request a copy of this report, please submit a Collision Data Request Form or for more information contact (360) 570-2541.
