A T-bone accident — also called a side-impact collision — happens when one vehicle strikes another directly in the side, forming a “T” shape. These crashes often occur at busy Sioux Falls intersections such as 41st Street & Louise Avenue, Minnesota Ave & 33rd Street, or 10th Street & Cliff Avenue.
Because the side of a vehicle offers little protection, T-bone impacts often cause serious injuries or fatalities. At Northern Plains Justice, our Sioux Falls car accident lawyers help victims hold negligent drivers accountable and recover fair compensation for their losses.
Why T-Bone Crashes Happen in South Dakota
Side-impact collisions usually result from failure to yield, running red lights, or distracted driving. Common causes include:
-
Ignoring traffic lights or stop signs
-
Turning left without yielding to oncoming traffic
-
Speeding through yellow lights
-
Distracted or impaired driving
-
Confusion at multi-lane intersections
-
Misjudging another driver’s speed on I-29 or I-90 exits
Many crashes happen when drivers rush through intersections at the last second — a split-second mistake that can permanently change someone’s life.
Common Injuries from T-Bone Accidents
Side impacts expose occupants to direct contact with the striking vehicle, often leading to severe trauma such as:
-
Traumatic brain injury (TBI)
-
Broken ribs, pelvis, or collarbone
-
Internal bleeding or organ damage
-
Whiplash and soft-tissue strains
-
Facial injuries from shattered glass or airbags
Even with side airbags, the impact force in a T-bone crash can exceed several tons, causing long-term or disabling conditions.
Who Is at Fault in a T-Bone Collision?
Fault depends on who violated the right-of-way. In most cases, the driver who ran a red light, failed to stop, or turned without yielding is responsible.
Our Sioux Falls accident attorneys investigate by:
-
Reviewing police and crash reports
-
Obtaining traffic-camera and intersection-signal data
-
Interviewing witnesses
-
Examining vehicle damage patterns
-
Downloading black-box (EDR) speed and braking data
Under South Dakota’s “slight versus gross” negligence rule, you may still recover compensation if your fault is only slight. Our Sioux Falls car accident lawyers work to prove the other driver’s negligence and maximize your recovery.
What to Do After a Side-Impact Collision
- Call 911 and request police and medical response.
- Get medical care immediately — some injuries appear hours later.
- Photograph the vehicles, traffic lights, and intersection.

- Avoid giving statements to insurers before speaking with your lawyer.
Evidence like skid marks, light timing, and surveillance footage can disappear fast — a prompt investigation is key to success.

Common Questions About T-Bone Accidents in Sioux Falls
T-bone accidents often happen at intersections and can cause serious injuries because the side of a vehicle offers less protection. These frequently asked questions explain fault, evidence, injuries, insurance issues, and compensation after a side-impact crash in South Dakota.
What is a T-bone accident?
A T-bone accident is a side-impact collision where the front of one vehicle strikes the side of another. These crashes often happen at intersections, stop signs, traffic lights, and driveways when one driver fails to yield or runs a red light.
Who is usually at fault in a T-bone accident?
Fault often depends on which driver had the right of way. A driver may be responsible if they ran a red light, failed to stop, failed to yield, turned unsafely, or entered an intersection when it was not safe to do so.
What evidence helps prove fault in a side-impact collision?
Important evidence may include police reports, witness statements, traffic camera footage, dashcam video, vehicle damage, skid marks, intersection layout, signal timing, and accident reconstruction analysis.
What injuries are common in T-bone accidents?
Common injuries include head injuries, concussions, neck injuries, back injuries, broken bones, shoulder injuries, hip injuries, internal injuries, spinal cord injuries, and soft tissue damage. Side-impact crashes can be especially dangerous for occupants on the struck side.
Can both drivers share fault for a T-bone crash?
Yes. In some cases, both drivers may share fault if each contributed to the crash. South Dakota fault rules can affect compensation when more than one party is responsible.
Should I talk to the insurance company after a T-bone accident?
You should report the crash, but be careful with detailed statements before understanding your rights. Insurance companies may use your words to dispute fault, minimize injuries, or reduce the value of your claim.
How can a Sioux Falls T-bone accident lawyer help?
A lawyer can investigate the intersection crash, preserve evidence, review police reports, gather witness statements, deal with insurance companies, calculate damages, and pursue compensation for medical bills, lost wages, and pain and suffering.
