A minivan carrying six people was involved in a motor vehicle accident Sunday night. The T-bone crash happened at the intersection of 7th Avenue and Broadway Road in Phoenix.

Three children were riding in the van when the crash occurred; two were taken to the hospital with serious physical injuries. In addition, three adults also sought medical attention following the crash.

The crash is still under investigation. Nothing more is known about the condition of those involved in the T-bone crash.

T-bone crashes, or broadside collisions, are the deadliest type of motor vehicle accident and often cause serious head injury to those involved. Common safety features - crumple zones built into the vehicle and air bags - don't offer as much protection in a t-bone crash as they do in a head-on or rear-impact collision.

In many instances, only a door and a window stands between those occupying one car and the other car itself in a side-impact collision. Side or curtain airbags can lessen the chance of injury in a T-bone crash, but not all models come equipped with the modern safety feature that was not made standard until 2009.

T-bone accidents occur most often in intersections, particularly those that are controlled by a traffic light or traffic sign. Running a red light or a stop sign can quickly turn into a fatal T-bone crash.

Head injury, brain injury and neck injuries are common in side-impact crashes, as well as broken or fractured bones.
