Rear-End and T-Bone Collisions: How Fault Is Decided

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 decide who was at fault. A car accident attorney looking at either type of crash usually begins with the sequence of events, from each car's speed to the signals that controlled traffic.
Why rear-end crashes happen
Many state traffic codes prohibit following another vehicle more closely than is reasonable and prudent, taking into account the speed of traffic and the condition of the road. Distraction is a frequent factor. NHTSA notes 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.
Whiplash and soft tissue injuries
Rear-end impacts are often linked to whiplash, a neck injury caused by a rapid back-and-forth movement of the head. Neck pain and headaches may not show up until hours after the crash, which is one reason prompt medical care matters. Insurers sometimes dispute injury claims from low-speed rear-end crashes, citing minor vehicle damage. Medical records and photos of both vehicles help answer that argument, along with imaging such as an MRI when a doctor orders one.
What causes T-bone crashes
In a T-bone crash, the front of one vehicle strikes the side of another, most often at an intersection. Typical causes include failing to yield on a left turn and running a red light or a stop sign. The sides of a car have less https://kameronkdqn741.talesignal.com/posts/which-insurance-pays-after-an-auto-accident-uninsured-motorist-pip-and-medpay room to absorb crash forces than the front or rear, which is why the Insurance Institute for Highway Safety (IIHS) rates side protection in a separate 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. Evidence can include 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 hold speed and braking data from the seconds before the crash. A car crash lawyer typically moves quickly to collect video, because many systems record over old footage within days or weeks.
Comparative negligence in these crashes
Fault is not always all or nothing. Most states apply some form of comparative negligence, which reduces a recovery by the injured person's percentage of fault. In states with modified comparative negligence, a person whose fault reaches 50 or 51 percent, depending on the state, may be barred from recovery, while pure comparative negligence allows a reduced recovery at any percentage of fault. A few jurisdictions still apply contributory negligence, which can bar recovery for any fault at all. 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 it cannot predict the outcome of any claim.
