524 F.Supp.3d 1090
D. Mont.2021Background
- June 2017 multi-vehicle collision on I‑90 near Clinton, MT: Deborah Alteneder (driver of a Chevrolet Impala) lost control in rainy conditions, crossed a 38‑ft unprotected median, and entered the westbound lane; both Alteneder and passenger Joshua Creel died.
- Mark Loy was driving a 2018 Kenworth T800 westbound for Active Truck Transport, attempting to pass another truck when the Impala entered his lane and struck the truck.
- Truck deceleration data show Loy was traveling ~67–70 mph and did not apply brakes until ~1 second before impact; posted truck speed limit was 65 mph.
- Montana Highway Patrol attributed fault to Alteneder (speed too fast for conditions and excessive steering input); scene was wet with standing water ruts.
- Plaintiff’s expert (Lew Grill) opined Loy breached industry standards by failing to reduce speed and keep adequate lookout and concluded the collision was preventable by Loy/Active; plaintiff sued for negligence, wrongful death, survivorship, and loss of consortium.
- Court granted summary judgment for Defendants, holding Plaintiff failed to show Loy’s alleged negligence was the cause of the crash and that Alteneder’s conduct was an independent intervening act severing causation.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Existence of duty | Loy owed ordinary and commercial duties to other road users (keep lookout, manage speed) | Loy owed same general duties but no special duty to anticipate another driver’s sudden loss of control | Duty existed as a matter of law (court recognized statutory and common‑law duties) |
| Breach (speed/operation) | Loy exceeded safe speed for wet conditions (67–70 mph), failed to reduce speed/passing prudently (Grill) | Loy’s speed (2–5 mph over limit) did not create a breach causing the collision | Breach as to Loy’s speed is triable (expert raises dispute), but no evidence Active breached its supervisory/maintenance duties |
| Causation — cause‑in‑fact | If Loy had driven slower or braked earlier, collision would have been avoided (Grill) | No evidence that a change in Loy’s speed or actions would have prevented the crash; Alteneder’s loss of control was the but‑for cause | No genuine dispute: plaintiff failed to show but‑for causation — Loy’s alleged negligence did not cause the accident |
| Causation — proximate/intervening cause | Loy should have foreseen accidents resulting from speeding in wet conditions | Alteneder’s overcorrection and crossing the median were unforeseeable, independent intervening acts that broke the causal chain | Alteneder’s conduct was an independent, unforeseeable intervening cause; proximate cause fails and severs Defendants’ liability |
