There are injured people.
'Feriti' = feh-REE-tee. Stress the second syllable. The 'r' is slightly rolled.
Say this immediately after reporting the accident to 112/118. It escalates the priority of the response and triggers both police and ambulance dispatch.
'Ci sono dei feriti' uses the existential 'ci sono' (there are). 'Dei feriti' = some injured people. Singular: 'C'è un ferito' (there is an injured person). This phrase prompts the operator to ask follow-up questions about the number and severity of injuries.
C'è una persona priva di sensi.
There is an unconscious person.
Maximum urgency — unconscious victims need paramedics immediately.
Uno dei conducenti sanguina abbondantemente.
One of the drivers is bleeding heavily.
Specific detail — helps paramedics prepare equipment.
Sembra che nessuno sia gravemente ferito.
It seems nobody is seriously injured.
Use when injuries appear minor — still warrant medical check.
Italy's emergency medical service (118) uses a colour triage system at accident scenes: red (immediate life threat), yellow (urgent), green (minor). Paramedics assess and tag each victim on arrival.
