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 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 will usually start with the sequence of events, from the speed of each car to the signals that controlled the intersection.

What causes rear-end collisions

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 crash lawyer may ask for the other driver's phone records when distraction is suspected.

In many rear-end crashes the trailing driver is found at fault, but that is not automatic. A car that cuts in and brakes suddenly, brake lights that fail or a vehicle backing up may shift part or https://travistmmg119.tearosediner.net/how-crash-reports-and-dashcam-video-shape-an-auto-accident-claim 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 prompt medical care matters. Insurance companies sometimes challenge injury claims after low-speed rear-end crashes, citing minor vehicle damage. Photos of both cars and the medical records help respond to 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, 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, 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 hold speed and braking data from the seconds before the crash. A car accident lawyer typically moves quickly to collect video, since many systems overwrite 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 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 percentage 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 against a government 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.
