 After a stateful request from a form submission, Turbo Drive expects the server to return an [HTTP 303 redirect response](https://en.wikipedia.org/wiki/HTTP_303), which it will then follow and use to navigate and update the page without reloading.
 
-The exception to this rule is when the response is rendered with either a 4xx or 5xx status code. This allows form validation errors to be rendered by having the server respond with `422 Unprocessable Entity` and a broken server to display a "Something Went Wrong" screen on a `500 Internal Server Error`.

 The reason Turbo doesn't allow regular rendering on 200's from POST requests is that browsers have built-in behavior for dealing with reloads on POST visits where they present a "Are you sure you want to submit this form again?" dialogue that Turbo can't replicate. Instead, Turbo will stay on the current URL upon a form submission that tries to render, rather than change it to the form action, since a reload would then issue a GET against that action URL, which may not even exist.
