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

Rear-end and T-bone collisions come up again and again in injury claims. The name of the crash describes how the vehicles met, but it does not decide 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.
What causes rear-end collisions
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. Distracted driving is a common 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.
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 https://rowanigef294.halcyonledger.com/posts/what-to-expect-from-the-insurance-adjuster-after-a-car-accident or all of the fault. In a multi-vehicle pileup, 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. 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, together with imaging such as an MRI when a doctor orders it.
How T-bone collisions 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. A car's sides have less space to absorb crash forces than its 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.
Disputes in these crashes often come down to who had the right of way. Evidence can include 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 hold speed and braking data from the seconds before the crash. A car crash 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 any fault at all. A car 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 against a government agency can require written notice much sooner. This is general information and not legal advice, and it cannot predict the outcome of any claim.
