Involved in Accident!
although based on my personal experience... pagawa mo na lang car mo and just be happy that no one was injured.
I don't think may insurance yung bumangga syo.
I don't think may pambayad yung driver syo.
The truck owner might offer na may shop sila na kaya gawin car mo - wag ka papayag.
***
you have the right to hit the brakes and stop whenever/wherever
the vehicle behind you should also stop
technically, wala kang ginawang mali, pero I don't think may aasahan ka sa bumangga syo.
