It is hard to paint with a wide brush here; rules for determining fault vary by locale (sometimes significantly), but there are absolutely situations where your vehicle might strike the rear of another vehicle, and you are found completely free of liability. Often, situations like: * You are stopped in traffic, the driver in the front reverses into you. * Traffic comes to a quick stop, you stop, and the driver behind you rear ends you and pushes you into the vehicle in front of you. Brake checking and unsafe lane changes might result in a split of fault in places that assign comparative negligence, which might be more of what you're thinking of. Often the idea here is that the driver in the rear could have done something more to avoid the accident. This is less likely to be determined to be the case when a vehicle is completely stopped in traffic and the driver has no options.
