First, search medical attention instantly, even when you don’t think you’re injured. Certain accidents like brain accidents won’t manifest instantly after an accident. There shall be even less time to pursue compensation should you consider that a government agency or employee’s negligence caused your injury. In these situations, you’ll have 90 days from the date of your accident to file a special administrative declare, and one 12 months to file a lawsuit. The first thing you must do after an accident – if you’re able to – is move away from the scene.
