In the movies, we see the Knight Bus to be bending, swerving and squeezing with a switch used by the driver, to avoid collision with other objects like people, other vehicles, etc.

It is also invisible so I want to learn what happens if it accidentally makes a collision? Couldn't find anything about this subject.

Reading the question Does the Knight bus actually move continuously on the roads, or does it teleport/apparate?, I can understand that it can teleport for transport, but I mean when not teleporting and when it is manually being driven, what would be the outcome of a collision is there example for it? (Like reversing what happened, memory wipes, or will be just a crash)

  • But like I said, it is moving on the road, not always teleporting and I don't think there is 0% chance of an accident.

    It doesn't collide with anything, because magic. We don't know what safeguards might be in place in case it ever did.

  • @randal'thor Still can't believe that meme is considered as an accepted explanation. But why not... Because magic.

In the books it's rather the reverse - the Knight Bus doesn't swerve around things, things move out of the Knight Buses way.

Ernie didn't seem to have mastered the use of a steering wheel. The Knight Bus kept mounting the pavement, but it didn't hit anything; lines of lamp posts, letter-boxes, and bins jumped out of its way as it approached and back into position once it had passed.

Later, at the mention of Voldemort...

Even Stan's pimples went white; Ern jerked the steering wheel so hard that a whole farmhouse had to jump aside to avoid the bus.

So as ever this is the movies getting things wrong. What would happen if the Knight Bus crashed? We don't know, since as long as it's functional, it can't crash.

  • thank you for the not "because magic" answer and trying to really give an answer to the question. What I wanted to learn is what was happening in the books and you explained it.
