What Is a T-Bone Accident?

Q: How do T-bone accidents happen?

T-bone accidents often happen at intersections when one driver enters or crosses another vehicle's path. Common causes include running a red light or stop sign, failing to yield before entering an intersection, turning left across oncoming traffic, distracted driving, misjudging another vehicle's speed or distance, and driving too fast to stop safely. California right-of-way rules (including California Vehicle Code § 21800) and the point and angle of impact can be relevant when determining what happened.

Q: Who is liable for a T-bone collision?

Liability usually depends on which driver failed to use reasonable care or violated applicable right-of-way rules. The driver who hit the side of the other vehicle is not automatically at fault, because the other vehicle may have entered the intersection on a red light, failed to yield, or pulled into the path of approaching traffic.

Q: What should you do after a side-impact collision?

After a side-impact collision, first get somewhere safe and seek medical attention if you are injured. If you are able to do so safely, you should call 911 and report the crash, photograph the vehicles and surrounding intersection, get the other driver's insurance and contact information, collect contact information from witnesses, preserve dashcam footage, and keep medical bills, reports, and repair records. You do not need to guess about fault at the scene, since evidence can be reviewed afterward.

Q: How long do you have to file a T-bone accident lawsuit in California?

California generally gives injury victims two years from the date of the crash to file a personal injury lawsuit (California Code of Civil Procedure § 335.1). Different deadlines can apply in some situations, such as claims involving a government entity, which generally require a separate claim to be presented within six months.

A T-bone accident happens when the front of one vehicle crashes into the side of another. These crashes often happen at intersections when a driver runs a red light, fails to yield, or turns across oncoming traffic.

If you were injured in a T-bone crash, a car accident lawyer can explain how fault and compensation may be handled.

At Sweet James, we have more than 25 years of experience helping people after serious vehicle accidents and can investigate what happened when responsibility is disputed.

How Do T-Bone Accidents Happen?

T-bone accidents often happen when one driver enters or crosses another vehicle’s path at an intersection.

Common causes include:

Running a red light or stop sign
Failing to yield before entering an intersection
Turning left across oncoming traffic
Distracted driving
Misjudging another vehicle’s speed or distance
Driving too fast to stop safely

California’s right-of-way rules address how drivers should approach intersections and when they must yield. California Vehicle Code § 21800 is one of the provisions that can become relevant when determining who had the right of way.

The point and angle of impact also matter. A crash into the driver’s door, for example, can affect occupants differently from a side impact toward the rear of the vehicle.

What Injuries Can a T-Bone Accident Cause?

T-bone crashes can cause serious injuries, especially when the impact hits close to where someone is sitting. Common injuries include:

Traumatic brain injuries
Neck and back injuries
Spinal cord injuries
Broken ribs, pelvis, arms, or legs
Internal injuries
Cuts, bruising, and soft-tissue damage

How badly someone is hurt depends on things like the speed of the vehicles, where the impact happened, and which part of the car was struck.

If you have pain or other symptoms after a broadside crash, getting appropriate medical care can also create records showing when the symptoms began and what treatment was required.

Who Is Liable for a T-Bone Collision?

Liability for a T-bone collision usually depends on which driver failed to use reasonable care or broke the applicable right-of-way rules.

The driver who hit the side of the other vehicle is not automatically at fault. The other vehicle may have entered the intersection on a red light, failed to yield, or pulled into the path of approaching traffic.

What Should You Do After a Side-Impact Collision?

After a side-impact collision, you should first get somewhere safe and seek medical attention if you are injured. If you are able to do so safely, you should:

Call 911 and report the crash
Photograph the vehicles and surrounding intersection
Get the other driver’s insurance and contact information
Collect contact information from witnesses
Preserve dashcam footage
Keep medical bills, reports, and repair records

You do not need to guess about fault at the scene. The evidence can be reviewed afterward to determine what each driver was doing.

Can You Recover Compensation After a T-Bone Accident?

Depending on the circumstances, you may be able to recover compensation for:

Medical expenses
Future treatment costs
Lost wages
Reduced earning capacity
Vehicle and property damage
Pain and suffering
Other accident-related losses

T-Bone Accident FAQs

Here are a few other common questions about side-impact collisions.

How Long Do You Have to File a T-Bone Accident Lawsuit in California?

California generally gives injury victims two years from the date of the crash to file a personal injury lawsuit, per California Code of Civil Procedure § 335.1. This deadline applies whether your T-bone accident claim is resolved through a lawsuit or settled beforehand, since the filing window can affect your leverage in negotiations.

Different deadlines can apply in some situations. For example, claims involving a government entity, such as a crash with a public vehicle or an intersection maintained by a city or state agency, generally require a separate claim to be presented within six months, well before the ordinary two-year period runs.

Can Both Drivers Be at Fault for a T-Bone Accident?

Both drivers can share fault for a T-bone accident when each person’s actions contributed to the collision.

For example, one driver may have failed to yield while the other was speeding. California’s comparative fault rules can then affect how damages are allocated.

What If the Other Driver Claims They Had the Right of Way?

Disagreements about who had the right of way are common in T-bone accidents, since both drivers often believe the other entered the intersection improperly. An insurer may rely on the other driver’s version of events, but a driver’s statement alone does not establish fault.

Evidence such as traffic signal timing, intersection camera footage, the point of impact on each vehicle, and independent witness accounts can help clarify what actually happened. In some cases, the damage pattern on the vehicles can also indicate which driver entered the intersection first or was moving faster at the time of impact.
