One dead after Tuesday crash on Highway 450
GILLETTE (WNE) — Wyoming Highway Patrol is looking at driver inattention as a possible factor in the first fatal crash in Campbell County this year.
At about noon on Tuesday, a 60-year-old woman from South Dakota died in a two-vehicle crash on Highway 450 between Highway 59 and Hilight Road.
Aaron Brown, senior public relations specialist for Wyoming Highway Patrol, said the woman was eastbound in a Can-Am Spyder three-wheeled motorcycle. A Ford F-250 pulling a flatbed trailer was ahead of her and slowed down for a turn near mile marker 62.
The Can-Am did not slow down and went straight into the trailer, Brown said; the woman died at the scene. The driver of the Ford was not injured.
“We’re looking at rider inattention, she could’ve been distracted by something, she just didn't slow down at all,” Brown said. “We had some sign of soft braking, which means she saw it at the last possible second.”
The woman was wearing a helmet, Brown said. He added that while helmets can save lives in many scenarios, in this case, hers didn’t make a difference due to the speed at which she was traveling.
The woman’s dog, which she had with her in a carrier, survived the crash and is now at the Animal Shelter in Gillette.
Officials are not releasing the woman's name at this time.
