These usually start with a horn and a hand. If the gesture is an insult in public, that's public insult under the Criminal Code. It does not mean the crash is all your fault. If the other person then closes in or blocks you, that can be looked at on its own, as coercion or as negligent injury.
In the public case, the person who gestured wasn't prosecuted. The person who boxed the other car in was sentenced. The acts got split. It wasn't about who got angry first. I'm not coaching a gesture, and I won't guess whether a prosecutor charges this one.
What you can do first
- 01Keep the whole dashcam clip. Don't cut it down to the one second of the gesture.
- 02In the statement, separate who did what, and how each car moved.
- 03Don't tell each other 'I'm guilty' in the group chat.

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.
