How Fault Works in Rear-End and T-Bone Car Accidents
By @emilianodmbq904
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 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 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. 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. A car 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, yet that result is not automatic. A car that cuts in and brakes suddenly, 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 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. Symptoms such as neck pain and headaches may not appear until hours after the crash, which is one reason a prompt medical evaluation 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.
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. 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 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. Occupants on the struck side can suffer serious injuries, including traumatic brain injury and 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. An auto accident attorney https://israelgoel456.unionquill.com/posts/what-nhtsa-data-show-about-car-crashes will usually try to collect video quickly, since many systems overwrite footage within days or weeks.
Shared fault and comparative negligence
Fault is often shared. Most states apply some form 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 level of fault. A few jurisdictions still apply contributory negligence, which can bar recovery for even slight fault. A motor vehicle accident attorney can explain which rule applies where the crash happened.
A note on deadlines
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.
