What is the difference between the ‘roadside’ and the ‘shoulder’?
The ‘shoulder’ is the area immediately adjacent to the roadway, which may or may not be present. The ‘roadside’ is the area beyond that.
- If First Harmful Event indicates collision with a ‘barrier’, ‘curb’, ‘ditch’, ’embankment’, ‘guardrail’, ‘traffic control device’, or ‘utility pole’ ‘light pole or other post/support’, then First Harmful Event Location should not be ‘roadway’.

The First Harmful Event Location field was completed appropriately for 93 percent of the reports reviewed. Of the portion that was considered unacceptable, almost 4 percent had issues with consistency, and slightly more than 2 percent had an empty field. Among the different police agency types and reporting methods (paper vs. electronic), the variation was minimal. Auditors representing law enforcement commented on confusion regarding the difference between roadway and roadside, and suggested further clarification on this distinction. In general, the inconsistencies were due to contradictory information in the narrative. There were no appreciable differences in findings since the previous 2005 audit.
