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

Rear-end crashes and T-bone collisions are two crash types that come up often in injury claims. The name of the crash describes how the vehicles met, but it does not decide who was at fault. An auto accident lawyer reviewing these crashes usually begins with the sequence of events, from each car's speed to the signals that controlled https://angeloskkl759.novacrestiq.com/posts/what-to-expect-from-the-insurance-adjuster-after-a-car-accident traffic.
How rear-end collisions 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. A car accident attorney 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, yet that result 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, every impact is its own 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. Symptoms such as neck pain and headaches may not appear until hours after the crash, which is one reason prompt medical care matters. Insurance companies sometimes challenge injury claims after low-speed rear-end crashes, citing minor 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, usually 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, 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 hold speed and braking data from the seconds before the crash. 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 often shared. 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 few jurisdictions still apply contributory negligence, which can bar recovery for even slight fault. A motor vehicle accident attorney will know which rule applies in the state where the crash happened.
A note on deadlines
Every 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 article is general information, not legal advice, and no article can predict how a claim will turn out.
