Negligence is the key factor in every Colorado personal injury case. Negligence means proving that someone else is at fault for your injury. To prove negligence, we have to establish three factors. The first is that the other person had a duty of care towards you. In simple terms, we have to prove that they were responsible for providing a safe environment, they were expected to act responsibly, and that they violated this duty by acting against their responsibilities. This is called the “reasonable person” standard. Next, we have to prove that their violating this duty of care led to the accident, even indirectly. The term for this is the “direct or proximate cause” of the accident. Finally, we need to establish that your injury occurred because of the accident.
