How Fault Works in Rear-End and T-Bone Car Crashes

Rear-end crashes and T-bone collisions are two crash types that come up often in injury claims. The label describes how the vehicles met, but it does not settle who was at fault. A car accident lawyer reviewing one of these crashes will usually start with the sequence of events, from the speed of each car to the signals that controlled the intersection.
How rear-end collisions happen
Many state traffic codes prohibit following another vehicle more closely than is reasonable and prudent, with attention to the speed of traffic and the condition of the road. Distracted driving is a common factor. NHTSA explains that sending or reading a text takes a driver's eyes off the road for 5 seconds, which at 55 mph is like driving the length of a football field with eyes closed. An auto accident attorney will sometimes request the other driver's phone records if distraction is suspected.
The trailing driver is often found at fault in a rear-end crash, but that is not automatic. A vehicle that cuts in and stops short, brake lights that fail or a vehicle backing up may shift part or all of the fault. In a multi-vehicle pileup, each impact is a separate event, and a middle car pushed into the car ahead may not be at fault for that second impact.
Neck injuries after a rear-end crash
Rear-end impacts are often linked to whiplash, a neck injury caused by a rapid back-and-forth movement of the head. Symptoms such as neck pain and headaches may not appear until hours after https://sethgykt310.readspirex.com/posts/how-fault-works-in-rear-end-and-t-bone-car-accidents the crash, which is one reason prompt medical care matters. Insurers sometimes dispute injury claims from low-speed rear-end crashes, pointing to light vehicle damage. Photos of both cars and the medical records help respond to that argument, along with imaging such as an MRI when a doctor orders one.
How T-bone collisions happen
In a T-bone crash, the front of one vehicle strikes the side of another, usually at an intersection. Typical causes include failing to yield on a left turn and running a red light or a stop sign. A car's sides have less space to absorb crash forces than its front or rear, and the Insurance Institute for Highway Safety (IIHS) evaluates side protection in its own side-impact crash test. People seated on the struck side can suffer serious injuries such as traumatic brain injury or pelvic fractures.
These crashes often turn on who had the right of way. Useful evidence includes signal timing records, intersection camera video, nearby business surveillance footage, dashcam video and witness statements, as well as the event data recorder (EDR) in each car, which may store speed and braking data from the seconds before impact. A car crash lawyer will usually try to collect video quickly, since many systems overwrite footage within days or weeks.
Comparative negligence in these crashes
Fault is not always all or nothing. Most states use some version of comparative negligence, which lowers a recovery by the injured person's share of fault. Under modified comparative negligence, a person found at least 50 or 51 percent at fault, depending on the state, may recover nothing, while pure comparative negligence allows a reduced recovery at any percentage of fault. A small number of jurisdictions still follow contributory negligence, which can bar recovery for even slight fault. An automobile accident lawyer will know which rule applies in the state where the crash happened.
Deadlines and general information
Each state sets its own statute of limitations for injury claims, and claims involving a government vehicle or agency can require written notice much sooner. This is general information and not legal advice, and no article can predict how a claim will turn out.
