The Signal4 Diagramming Tool is used for diagramming crashes by law enforcement officers.
Signal4 Diagramming Tool is implemented by your agency’s e-reporting system. Several systems used across the state, such as TraCs, already have the Signal4 Diagramming system implemented and you simply need to reach out and ask your e-reporting system for access.
For those that do not have the system implemented, reach out to your agency’s IT department and direct them towards us.
