A T-bone accident happens when the front of one vehicle crashes into the side of another, creating a shape similar to the letter “T.” These crashes are especially common at intersections and can cause serious injuries because drivers and passengers have less protection from a side impact.
Determining who is at fault for a T-Bone accident depends on what led to the crash. The driver who violated another motorist’s right-of-way is often responsible, although there are situations where both drivers may share fault.
Who Is Usually Responsible for a T-Bone Accident?
There is no rule that automatically makes one driver responsible for every T-bone collision. Instead, determining fault usually comes down to each driver’s actions in the moments leading up to the crash.
Common examples of negligence that can cause a T-bone accident include:
- Running a red light or stop sign
- Failing to yield the right-of-way
- Making an unsafe left turn
- Speeding through an intersection
- Driving while distracted
- Driving under the influence
- Misjudging the speed or distance of another vehicle
Arizona law requires drivers facing a steady red traffic signal to stop before entering an intersection. Drivers making certain turns must also yield to traffic that has the right-of-way. When a driver ignores these rules and causes a crash, their actions can be important evidence of fault.
Is the Driver Who Hits the Other Car Always at Fault?
No. It may seem logical to blame the driver whose vehicle struck the side of the other car, but the point of impact does not tell the whole story.
Imagine that Driver A has a green light and begins traveling through an intersection. Driver B runs a red light and suddenly crosses Driver A’s path. Driver A may have little or no time to stop before hitting the side of Driver B’s vehicle. In that case, Driver B could be primarily responsible even though their vehicle was the one struck from the side.
Left-turn accidents provide another common example. Arizona law generally requires a driver turning left at an intersection to yield to oncoming traffic that is in the intersection or close enough to present an immediate hazard. A driver who turns across the path of an approaching vehicle could therefore be responsible for the resulting T-bone crash.
What Evidence Can Establish Fault for a T-Bone Crash?
Figuring out what happened is not always straightforward. Drivers may remember the collision differently, and both might insist they had the right-of-way. Evidence from the scene can help provide a clearer picture.
Important evidence may include:
- Police accident reports
- Photographs and videos from the crash scene
- Traffic or surveillance camera footage
- Eyewitness statements
- Vehicle damage
- Skid marks and other physical evidence
- Cellphone records
- Event data recorder information
In a serious or disputed case, an accident reconstruction expert may also examine the vehicles, roadway, impact points, and other physical evidence to help determine how the crash occurred.
How Can Fault Affect a T-Bone Accident Claim?
Determining fault is a key part of a T-bone accident claim. Someone injured because of another person’s negligence may be able to seek compensation for the financial and personal consequences of the crash.
In some T-bone accidents, both drivers may have contributed to the collision. For example, one driver might fail to yield while the other is speeding, meaning both drivers’ actions could factor into the determination of fault.
Depending on the circumstances, damages may include medical expenses, lost income, reduced earning capacity, property damage, pain and suffering, and other accident-related losses.
Fault can also become one of the most contested parts of an insurance claim. An insurer may dispute its policyholder’s responsibility or argue that the injured person contributed to the crash. Preserving evidence as soon as possible after the accident can help establish what actually happened.
