I don't know exactly where I am.
'Esattamente' = eh-zat-ta-MEN-teh. 'Dove' = DOH-veh (where). Key phrase for giving location.
When calling emergency services from an unfamiliar location — describe surroundings to help locate you.
'Non so' (I don't know) uses the irregular present of 'sapere'. 'Dove sono' is a question embedded in a statement. Location is the most critical piece of information for emergency services. If you cannot give an address, describe landmarks: 'sono vicino a...' (I'm near...), 'vedo un...' (I can see a...), 'sono su una strada statale' (I'm on a main road). Modern mobiles transmit GPS location to 112.
Sono su una strada secondaria, non vedo segnali.
I'm on a secondary road, I don't see any signs.
Describe what you can see — road type, landmarks, vegetation, lighting.
L'ultimo segnale che ho visto era 'Castelfranco 3 km'.
The last sign I saw said 'Castelfranco 3 km'.
Give the last identifiable point — operators can triangulate.
Posso attivare la posizione GPS per il 112?
Can I activate GPS location for 112?
Modern smartphones automatically share location when calling 112.
