The Oklahoma Highway Patrol says a truck driver and passenger were hurt when the rig rolled over Friday morning.
Troopers say both are being checked out at a hospital for minor injuries.
The OHP says the crash happened on I-44 where it meets I-244 shortly after 5 a.m. Troopers say the driver failed to negotiate a curve and the truck ended up on its side in the center median.
The truck was carrying office supplies.
One westbound lane of I-44 at the split with I-244 remains closed because of the accident.
