T-bone accidents, also known as side-impact collisions, often happen at intersections and can cause severe injuries. Determining fault in these crashes is critical because it affects insurance claims, liability, and your ability to recover compensation. In California, fault is based on negligence, and understanding how it is determined can help protect your rights. At Wilshire Law Firm, we help accident victims navigate the legal process and pursue fair compensation. If you have questions about fault or your claim, we offer free consultations and take no fees unless you get paid.
What Is a T-Bone Accident?
A T-bone accident occurs when the front of one vehicle strikes the side of another, forming a “T” shape. These collisions often happen at:
- Intersections
- Parking lots
- Areas where drivers fail to yield or obey traffic signals
Because the sides of vehicles offer less protection than the front or rear, injuries in T-bone crashes can be severe.
How Is Fault Determined in a T-Bone Collision?
Fault in a T-bone accident depends on who violated traffic laws or acted negligently. Common factors include:
1. Traffic Signal Violations
Running a red light or stop sign is a leading cause of T-bone crashes. The driver who ignored the signal is usually at fault.
2. Failure to Yield
Drivers making left turns or entering intersections must yield to oncoming traffic. Failure to do so can establish liability.
3. Speeding or Distracted Driving
Excessive speed or inattention can contribute to fault in side-impact collisions.
4. Comparative Negligence
California follows a pure comparative negligence rule, meaning fault can be shared. If both drivers contributed to the crash, each party’s compensation may be reduced by their percentage of responsibility.
Evidence Used to Determine Fault
Insurance companies and courts rely on evidence such as:
- Police reports
- Witness statements
- Traffic camera footage
- Photos of the accident scene and vehicle damage
Gathering strong evidence is essential for proving liability.
Common Injuries in T-Bone Accidents
Side-impact collisions can cause:
- Head and brain injuries
- Neck and spinal injuries

- Internal organ damage
These injuries often require extensive medical care and can lead to long-term complications.
