What a Car Accident Attorney Looks at After a Rear-End or T-Bone Crash

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. An auto accident lawyer reviewing 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. 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. An auto accident attorney may ask for the other driver's phone records when 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 do not work or a vehicle backing up may shift part 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 associated with whiplash, a neck injury caused by the head snapping back and forth. Neck pain and headaches may not show up 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, pointing to light 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.

What causes T-bone crashes

In a T-bone crash, 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. People seated on the struck side can suffer serious injuries such as traumatic brain injury or 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.

Shared fault and comparative negligence

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 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.
