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

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 settle 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.
Why rear-end crashes happen
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 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 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 can shift some 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 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, 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.
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. 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 https://milomujl986.northvaledigest.com/posts/uninsured-motorist-pip-and-medpay-coverage-explained serious injuries, including traumatic brain injury and pelvic fractures.
Disputes in these crashes often come down to who had the right of way. Useful evidence includes 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 hold speed and braking data from the seconds before the crash. An auto accident attorney will usually try to collect video quickly, because many systems record over old footage within days or weeks.
Shared fault and comparative negligence
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 percentage of fault. A small number of jurisdictions still follow contributory negligence, which can bar recovery for any fault at all. A motor vehicle accident attorney can explain which rule applies where the crash happened.
Deadlines and general information
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 it cannot predict the outcome of any claim.
