No, a rear driver is not always liable for a rear-end collision. Many states have a presumption that holds a rear driver liable, unless they are able to prove otherwise, since each driver is expected to maintain their safe following distance from the car in front of them. Nevertheless, the front driver may be liable in some situations, such as stopping to make a turn without using the turn signal, failing to pull over when the car breaks down, or failing to repair faulty brake lights.
