A 41-year-old Arnprior man was killed when he was partially ejected from his vehicle on Highway 417 Tuesday morning.

Ontario Provincial Police say Ronald Levesque was driving westbound near Galetta Side Road when he lost control of his vehicle, flipping his pickup truck into a ditch.

Levesque was pronounced dead at the scene. Police are investigating speed as a possible factor in the crash.

The collision, which occurred at 5:50 a.m., closed the westbound lanes of the highway near Arnprior for several hours. The highway reopened just after 1 p.m.
