Usually, but not always.
Rear-end crashes are the most common type of vehicle accident in the United States, accounting for about 1.7 million crashes each year. Of those crashes, about 1,700 are killed and an additional 500,000 are injured. If you have been driving for any length of time, you are probably under the impression that the driver of the following vehicle (the one that crashes into the back of the lead vehicle) is always at fault for rear-end accidents. While it is true that the drivers of rear vehicles in rear-end crashes are usually mostly at fault, there are several situations that can reduce or entirely eliminate the rear driver’s liability.
