The usual rear-end: the front car is in its lane, and the car behind didn't keep a safe gap. The talk sits on the car behind. The other version: the car in front of you got shoved by someone further back. What you felt as 'they hit me' is the second impact. No dashcam, and the whole thing gets told as a simple rear-end.
'Didn't keep a safe distance' and 'didn't watch ahead' are the words of a traffic violation. They are not a civil split of 100. If the hard brake had no reason, or someone cut in, what the front car did gets looked at too.
What you can do first
- 01The video needs about five seconds before the hit, and whether another car was still behind.
- 02Photograph skid marks and debris before anyone moves the cars.
- 03Three cars or more: write each policy down on its own. Don't only chase the one in the middle.

Rewritten in my own words. Not a judgment and not a law firm's article. If a number shows up, it belonged to that public discussion, not to you. Check the Judicial Yuan judgment system. These started as public discussions of car crashes. I rewrote them here. Not a law firm's article.
I'm not a lawyer, and I'm not a mediator. I can't decide this for you. The statute that counts is the one still in force. Judgments live on the Judicial Yuan site.
