A weekend ride on Highway 20 outside Malheur County ended in tragedy when a Harley-Davidson collided with a semi-truck Saturday morning, killing the rider and seriously injuring his passenger. The crash shut down the rural stretch of highway for about two hours as troopers investigated.
Authorities identified the motorcyclist as 67-year-old John Platt of Winters, California. His passenger, 70-year-old Yolanda Platt, was taken from the scene with serious injuries. The semi-truck driver was not hurt.
State police account
According to the Oregon State Police, the collision happened at about 9:44 a.m. near milepost 255 on Highway 20. Investigators say a white Peterbilt semi-truck towing a trailer was heading west when the driver attempted a left turn onto Siphon Drive. As that maneuver was underway, the westbound motorcycle attempted to pass and struck the driver side of the truck.
Troopers reported that John Platt was pronounced dead at the scene. Treasure Valley Paramedics and the Oregon Department of Transportation assisted on site while the highway remained blocked for roughly two hours.
Who was involved
Follow-up reporting based on the state release identified the semi-truck driver as 24-year-old Victor Pena-Olvera of Marsing, Idaho, and confirmed the motorcycle involved was a black Harley-Davidson. As reported by KOIN, authorities publicly named John and Yolanda Platt as the motorcycle’s rider and passenger. The semi-truck operator was not injured.
Motorcycle safety on rural highways
Crashes like this one highlight how vulnerable riders are on open highways. National Highway Traffic Safety Administration 2024 data shows motorcyclists have a fatality rate of roughly 28.00 per 100 million vehicle miles traveled, compared with 1.05 for people in passenger vehicles.
In Oregon, crash tools and mapping systems maintained by the Department of Transportation help pinpoint where serious wrecks are happening on rural corridors such as Highway 20, giving investigators and safety planners a clearer picture of trouble spots.
Investigation ongoing
The Oregon State Police say the investigation into the Malheur County crash is still active, and no findings about cause or fault have been released. Troopers noted that traffic on Highway 20 was affected for about two hours during on-scene work. Officials say future updates will be provided through the Oregon State Police as the inquiry continues.
