What Is a Rear-End Collision Truck Accident?

Rear-end collisions involving commercial trucks are among the most common and deadliest crashes on US highways. The stopping distance of a loaded 80,000-lb semi traveling at 65 mph is roughly 525 feet — nearly two full football fields — meaning following-distance violations are frequently the root cause.

Common Causes

→Insufficient following distance (FMCSA violation)
→Distracted driving — phone use, dispatch communication
→Driver fatigue and hours-of-service (HOS) violations
→Brake failure or degraded brake performance
→Hydroplaning or loss of traction in wet conditions
→Sudden traffic slowdown in construction zones or merge points

Common Injuries

→Whiplash and cervical spine injuries
→Traumatic brain injury (TBI) from head whip
→Thoracic and lumbar spinal compression fractures
→Seat belt-related chest and abdominal injuries
→Rear intrusion crush injuries
→Wrongful death

Key Evidence & Liability Factors

▸Driver's electronic logging device (ELD) for HOS violations
▸Event data recorder (EDR) showing speed and brake timing
▸Cell phone and dispatch communication records
▸Dashcam footage from the truck or trailing vehicles
▸Pre-trip inspection records for brake condition

FMCSA note: FMCSA 49 CFR § 392.22 requires drivers to maintain safe following distances. HOS violations under 49 CFR Part 395 are frequently cited as a contributing factor in rear-end fatigue crashes.

South Dakota Fault Laws and How They Affect Your Settlement

South Dakota follows pure comparative fault. This is governed by South Dakota Codified Laws § 20-9-2 (pure comparative fault).

South Dakota Fault Rule: Pure Comparative Fault

Under S.D. Codified Laws § 20-9-2, you can recover damages even if you were 99% at fault — your award is simply reduced by your percentage of fault.

Example: Your damages total $1,000,000. You are found 40% at fault. Your net recovery: $1,000,000 × (1 − 0.40) = $600,000.

Major South Dakota freight corridors: I-90, I-29, US-83, US-14, SD-44 — these interstates carry the highest commercial truck traffic volume in the state and account for a disproportionate share of large truck crashes.
