Tulsa, Okla. -- At least four people were taken to the hospital after a car wreck caused multiple collisions on Highway 412, Monday morning.

Police said 22-year-old Shannon Laney of Broken Arrow, Okla. was driving a 2007 Ford when she lost control and spun out on the Verdigris River Bridge.

Officers were trying to help clear the roadway when a semi-truck, driven by 47-year-old Gheorje Popouici of Highland, Cali., came across the bridge and lost control. The semi-truck hit Laney's car.

Two more vehicles--a 2000 Pontiac Grand Am driven by 37-year-old Bernardino Rodregez of Gentry, Ark., and a 2001 Chevy Malibu driven by Rebecca Hathcoat of Wagoner, Okla.--also hit Laney's car.

According to an Oklahoma Highway Patrol report, Laney was taken to the hospital in serious condition with internal injuries.  Rodregez was treated at the hospital for arm, head, and leg injuries. Popouici and a passenger in his truck were not injured and neither was Hathcoat or her passenger.

But the wrecks did not stop there. These wrecks caused several other accidents on Monday morning, including one involving emergency vehicles. A fire truck and ambulance, both on their way to the collision scene collided with each other, pinning a firefighter for a short time and injuring several other firefighters and paramedics.

The Oklahoma Department of Transportation said drivers need to use extreme caution when driving on the slick roads.

"Slow down, ealier this morning I was sitting with OHP and they were clocking cars at 70-75 miles-per-hour.  People just need to slow down," said Martin Stewart, with the Oklahoma Department of Transportation. "The roads look wet, the bridges and overpasses look wet, but they are extrememly slick."

The eastbound lanes of Highway 412 were shut down for about three hours while crews cleaned up the collision scene.
