On Monday (3/11) at approximately 3:20 PM, Mohave County Sheriff’s Office Deputies responded to milepost 20 on Oatman Highway in reference to a vehicle collision. The reporting party advised a motorcycle had collided with a truck and the motorcycle operator was unconscious. It was reported to deputies that the motorcycle was traveling north bound and failed to negotiate the curve in the road. The motorcycle crossed the center line just as the truck was coming around the curve from the opposite direction and the motorcycle collided with the side of the truck. It appeared to deputies that the motorcycle operator was not wearing a helmet at the time of the collision and he was transported to a Las Vegas hospital for serious injuries.
