How Fault Works in Rear-End and T-Bone Car Accidents
By @zanexyjs138
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 attorney looking at either type of crash usually begins with the sequence of events, from the speed of each car to the signals that controlled the intersection.
Why rear-end crashes happen
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. Distraction is a frequent 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. 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, but that is not automatic. A vehicle that cuts in and stops short, brake lights that fail or a vehicle backing up may shift part or all of the fault. In a chain-reaction crash, every impact is its own event, and a middle car pushed into the car ahead may not be at fault for that second impact.
Whiplash and soft tissue injuries
Rear-end impacts are often associated with whiplash, a neck injury caused by a rapid back-and-forth movement of the head. Symptoms such as neck pain and headaches may not appear until hours after the crash, which is one reason a prompt medical evaluation matters. Insurance companies sometimes challenge injury claims after low-speed rear-end crashes, pointing to light vehicle damage.

How T-bone collisions happen
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, as well as the event data recorder (EDR) in each car, which may store speed and braking data from the seconds before impact. A car accident lawyer will usually try to collect video quickly, since many systems overwrite 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. 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
Every 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 it cannot predict the outcome of any claim.
