Rosas failed to negotiate a curve in the roadway and crossed the centerline. As a result, the right front of the Buick struck the motorcycle in the eastbound lane. The cycle was then propelled from the roadway onto the south grassy shoulder.
Rosas separated from the cycle and came to final rest on the south grassy shoulder. The vehicle also came to rest on the grassy shoulder. The Buick came to rest partially in eastbound lane and paved apron of the roadway.
The crash is under investigation to determine if alcohol was a factor for Rosas.
