About Leaving the scene of an accident is a criminal offence — and the PAMAN order: which statement is WRONG?
If you hit a parked (empty) car, you don't need to do anything as long as there is no driver present to talk to.
You describe as exactly as possible where you are, what happened, how many vehicles are involved and how many (seriously) injured there are — 'that way the right services arrive fastest'.
AMAN starts with Personal safety; Alerting is only the fourth step.
The prohibition applies to death, injury OR damage.

trap: treating the other party's absence as a free pass. Book p.171 - for exactly this case the book gives a concrete duty: leave your contact details at the damaged vehicle and inform the police. 'That is mandatory'
