Figure 2. Figure 2. BAC testing and reporting for drivers who die at the crash scene - flow diagram, level 1 "driver dead at scene" (flows to level 2, designated (A). level 2 - "coroner or medical examiner draws blood", flows into level 3, designated (B). Level 3 - "blod sent to lab; lab determined BAC", flows into levels 4 and 5. Level 4, designated (C) "BAC sent to law enforcement of prosecutor's office, flows into level 5. Level 5 - "BAC sent to FARS"

Figure 3. BAC testing and reporting for drivers taken to a treatment facility - flow diagram, level 1 "driver injured at scene, taken to ED or hospital" - flows into level 2. Level 2 - "ED or hospital draws blood (A)", flows into level 3. Level 3 - "blood sent to lab; lab determines BAC" and "hospital determines BAC (B)", flows into levels 4 and 5. Level 4 - "BAC sent to law enforcement or prosecutor’s office", flows into level 5. Level 5 - "BAC to FARS"

Figure 4. BAC testing and reporting for drivers remaining at the crash scene - flow diagram, level 1 "law enforcement determines whether to acquire BAC evidence (A)", flows into level 2. Level 2 - "breath test" or "blood draw (B)", flows into level 3. Level 3 - " BAC to crash report" (flows into level 5)or "blood sent to lab; lab determines BAC" (flows into level 4). Level 4 - " BAC to law enforcement or prosecutor’s office", flows into level 5. Level 5 - " BAC to FARS"
