Rear-end car accidents collisions are very common in South Florida. Some occur at intersections and any more occur on the highways. Some of the worst types of accidents involve sometimes tens of vehicles at a time. And, of course, there are rear-end collisions in parking lots of shopping centers and at restaurants. In Florida, when an accident is caused by a rear-end collision, the rear driver is presumed to be at fault. Generally, to prove negligence in a rear-end collision case, there must be a breach of the duty of care. Generally, where other vehicles are able to stop behind the lead vehicle, the driver of the last vehicle that precipitates the chain reaction collision has breached the duty of care and is negligent. In a rear- end collision case, it must be established that the defendant’s negligence caused the accident. Causation is often disputed. In cases where the rear- end collision involves more than two vehicles, causation is an issue that can become complicated.
