 WHP Releases Information On Fatal Crash West of Buffalo

The Wyoming Highway Patrol has released more information on the fatal crash that happened Sunday afternoon on Highway 16 west of Buffalo.

According to their report, the crash happened at 4:05pm about 4 miles west of Buffalo.

Killed in the crash was 44 year-old Oscar L. Viscarra of Lewisville, Texas.

Viscarra was driving a 2001 Kenworth tractor and trailer licensed to JC & Sons Transport when the crash occurred.

The WHP Report reads: Vizcarra was traveling eastbound going down a long steep descending grade nearing the bottom of Powder River Pass just outside of Buffalo. Vizcarra was pulling a fully loaded flatbed trailer that was loaded with bags of bentonite. Witnesses told Troopers that the brakes were smoking on Vizcarra’s tractor trailer combination prior to the crash as he was descending the grade. For reasons unknown, Vizcarra drove past the marked and signed runaway truck ramp after which he attempted to negotiate a left hand curve in the roadway. The combination jackknifed and skidded off the right side of the roadway going through the guardrail. The vehicle then went over an embankment dropping 300 feet whereupon the combination came to rest on the banks of (Clear Creek). Vizcarra was totally ejected from the cab of the truck tractor.
Troopers investigating this crash believe failing to use lower gears to slow the loaded tractor trailer combination down the steep grade lead to overheated brakes was a contributing factor in this crash.
