crash into — movement prepositions with impact (GiU Unit 126/136)

The frame

There was an awful noise as the car crashed into a tree. ✓ (✗ crashed in a tree · ✗ crashed with a tree)

Why into

into = movement to a point, ending inside/at contact. The crash is motion → you need the directional into, not the static in:

static (position)	directional (motion)
in the room (inside)	go into the room
in the tree (up there)	crash into the tree

The impact-verb family (all + into)

• crash into a tree/wall
• bump into a person (also: meet by chance)
• drive into a shop window
• walk into a door (also: enter, or get tricked)
• run into a lamppost (also: meet by chance)
• reverse into, sail into, plough into

All describe making forceful contact → the object is the contact point, reached by motion.

The in / into / on split

preposition	idea	example
in	static, enclosed	the car is in the garage
into	motion → entering/impact	the car crashed into the wall
on	surface contact	the book is on the table
onto	motion → surface	he jumped onto the stage
