accident

It was a night,my father drived a car with my on autoroutemother and i.We had went to my grandparent'home that day.Because it was night and there were a few cars on the road,my father drived on the speed way and tried to be faster.Suddenly, the car bumped something,and i had no reaction about it ,so the seat which my father sat and my face had a big dump.At that time , my nose was blooding.My father let us get out of the car and tried to made it work.After that i made two question clearly,what we had jumped and what it is.We had bumped a truck which was breaking down and have no back-light.
