A traffic control should be reported for each unit in a crash (except pedestrians); multiple traffic controls are noted in multiple unit crashes. The controls can be the same for each unit or different. If they are the same, both are listed. Fewer than one control would be noted if the officer didn’t record a traffic control. For example, controls are not required to be noted for single unit, property damage deer crashes.
