What Is a T-Bone / Side-Impact Truck Accident?

T-bone accidents occur when the front of a truck strikes the side of another vehicle — or vice versa — at an intersection or merge point. Because vehicle side panels offer far less structural protection than front or rear structures, side-impact crashes with large trucks often result in occupant compartment intrusion and severe injuries.

Common Causes

→Truck running a red light or stop sign
→Failure to yield on left turns across traffic
→Misjudging gap in traffic at uncontrolled intersections
→Brake failure preventing a stop before an intersection
→Driver distraction during approach to controlled intersection

Common Injuries

→Thoracic crush injuries from door intrusion
→Pelvic and hip fractures
→Shoulder, arm, and rib fractures
→Traumatic brain injury from lateral head movement
→Spinal injuries from lateral loading
→Wrongful death

Key Evidence & Liability Factors

▸Traffic signal and red-light camera footage
▸Intersection surveillance video
▸ECM speed and brake data approaching the intersection
▸Witness accounts of traffic signal status
▸Brake maintenance records for stopping ability

FMCSA note: FMCSA 49 CFR § 392.10 governs railroad grade crossing rules, but intersection compliance falls under state traffic law. Carrier liability is established through respondeat superior and negligent entrustment.

Idaho Fault Laws and How They Affect Your Settlement

Idaho uses the 50% bar rule. This is governed by Idaho Code § 6-801 (modified comparative fault, 50% bar).

Idaho Fault Rule: Modified Comparative Fault (50% Bar)

Under Idaho Code § 6-801, if you are assigned 49% or less of the fault, your damages are reduced proportionally. If you are assigned 50% or more, you recover nothing.

Example: Your damages are $600,000 and you are 30% at fault. Recovery: $600,000 × 0.70 = $420,000.

Major Idaho freight corridors: I-84, I-86, I-15, US-95, US-93 — these interstates carry the highest commercial truck traffic volume in the state and account for a disproportionate share of large truck crashes.
