Left-Turn and T-Bone Accident Fault

Quick Answer. A T-bone describes where vehicles collided, not necessarily who violated a rule. A left-turn claim requires evidence about right of way, signals, approach speed, visibility and the movements of both vehicles.

Start With the Movement, Not the Damage Label

Was a vehicle turning left across oncoming traffic, leaving a driveway, crossing a stop-controlled road or proceeding through a signal? These are different situations even when the damage looks similar.

Draw a simple diagram with street names, travel directions, lanes and traffic controls. Mark where you were when you first saw the other vehicle. Use photographs to support the diagram, and label estimates rather than presenting them as measured distances.

What Does a Left-Turn Rule Require?

New York Vehicle and Traffic Law 1141 requires a driver turning left to yield to oncoming traffic in or close enough to the intersection to create an immediate hazard. It is a state-specific example of a right-of-way rule, not proof that every turning driver is always fully liable. New York: Vehicle and Traffic Law 1141

Identify whether a protected arrow, ordinary green light or another control was involved. If speed or a red-light violation is disputed, ask what evidence supports each account. A witness who arrived afterward may describe vehicle positions but cannot necessarily describe the signal at impact.

Preserve Intersection Evidence Early

• Save original dashcam recordings, including the approach to the intersection.
• Photograph signals, lane markings, stop lines and visibility obstructions from safe locations.
• Note nearby businesses or residences that may have cameras.
• Record witness contact information and what each person saw.
• Keep the report number and ask how to obtain supplements or diagrams.

Ask about preservation of footage promptly. Do not assume traffic cameras save recordings or that footage remains available indefinitely. A lawyer can assess whether a formal request or other evidence-gathering step is appropriate.

What If Both Drivers Made Mistakes?

The state comparative-negligence rule determines the effect of shared responsibility. For example, Connecticut Section 52-572h sets a statutory comparison and reduction framework. Its application depends on which parties and conduct are involved. Connecticut: Section 52-572h

Do not collapse two separate questions—whether someone violated a rule and whether that conduct caused the collision—into a single accusation. Ask an insurer to explain both its factual account and its allocation.

Connect the Crash to the Actual Loss

Keep medical records, repair estimates and income documentation. If a door or seat area was damaged, preserve photographs before repairs. Describe your seating position and symptoms accurately without using the collision shape as a diagnosis.

Questions for a Consultation

Ask what evidence would resolve the disputed signal or turn, whether inspection is needed, which insurers should receive notice and what deadlines apply. Bring any proposed release. A claim’s practical strength depends on the evidence available, not on the phrase “T-bone” or “left-turn accident” in a form.
