This is a fairly classic accident. Firsty, you need to contact the police and report it as an injury collision as this needs to be reported on paper now.
The police were quite right first time round, damage only collisions are NOT recorded unless there is very obvious road traffic offences.
In this instance it is likley to be 50/50.
Yes, the truck driver should have given way - but, another determining factor is that you were on the wrong side of the carriageway. Overtaking on the approach to a junction is always a bit iffy.
Without witnesses a prosecution is not likley to be very forthcoming, and even in the civil court apportioning blame is going to be difficult.
