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 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 laws bar drivers from 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. A car crash lawyer will sometimes request the other driver's phone records if distraction is suspected.
In many rear-end crashes the trailing driver is found at fault, 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 chain-reaction crash, each impact is a separate event, and a middle vehicle pushed forward may not be responsible for the second impact.
Neck injuries after a rear-end crash
Rear-end impacts are often linked to whiplash, a neck injury caused by the head snapping back and forth. Neck pain and headaches may not show up until hours after the crash, which is one reason a prompt medical evaluation matters. Insurance companies sometimes challenge injury claims after low-speed rear-end crashes, pointing to light vehicle damage. Medical records and photos of both vehicles help answer that argument, together with imaging such as an MRI when a doctor orders it.
Why side-impact crashes happen
A T-bone collision happens when the front of one vehicle strikes the side of another, most often at an intersection. Common causes include running a red light or a stop sign and failing to yield on a left turn. The sides of a car have less 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. Useful evidence includes signal timing records, intersection camera video, nearby business surveillance footage, dashcam video and witness statements, plus the event data recorder (EDR) in each car, which may store speed and braking data from the seconds before impact. A car accident lawyer will usually try to collect video quickly, because many systems record over old footage within days or weeks.
When both drivers share fault
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. 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 level of fault. A small number of jurisdictions still follow 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
Every state sets its own statute of limitations for injury claims, and claims against a government agency can require written notice much sooner. https://travisfyhu260.trexgame.net/how-to-choose-a-car-accident-attorney This is general information and not legal advice, and it cannot predict the outcome of any claim.
