About Leaving the scene of an accident is a criminal offence — and the PAMAN order: which statement is WRONG?
The prohibition applies to death, injury OR damage.
The book names location, situation, number of vehicles and number of injured — a driving licence number is nowhere named as required 112 information.
When calling 112 it is enough to say there has been an accident; the exact location and number of injured can follow later.
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'.
Explanation
trap: report kept too vague. Book p.170 - 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'
