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

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

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. A car accident attorney looking at either type of crash 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 laws bar drivers from following another vehicle more closely than is reasonable and prudent, with attention to 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, https://milomujl986.northvaledigest.com/posts/how-fault-works-in-rear-end-and-t-bone-car-crashes 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 car pushed into the car ahead may not be at fault for that second impact.

Neck injuries after a rear-end crash

Rear-end impacts are often associated with whiplash, a neck injury caused by a rapid back-and-forth movement of the head. Neck pain and headaches may not show up 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, pointing to light vehicle damage. Photos of both cars and the medical records help respond to that argument, together with imaging such as an MRI when a doctor orders it.

Why side-impact crashes happen

In a T-bone crash, 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. 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 typically moves quickly to collect video, because many systems record over old footage within days or weeks.

When both drivers share fault

Fault is often shared. Most states use some version of comparative negligence, which lowers a recovery by the injured person's share of fault. In states with modified comparative negligence, a person whose fault reaches 50 or 51 percent, depending on the state, may be barred from recovery, 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 car accident attorney will know which rule applies in the state where the crash happened.

A note on deadlines

Each 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 no article can predict how a claim will turn out.
