An Acadian ambulance spun out of control, ending up on its side after another vehicle smashed into it from behind on Interstate 10 near Gramercy Sunday morning, sending four to the hospital, company officials said.

Two medics were transporting a patient from New Orleans to an undisclosed location when another vehicle traveling fast crashed into the back of the ambulance at about 6:30 a.m., said Randall Mann, vice president for marketing and government relations at Acadian.

The ambulance flipped and crashed, Mann said, injuring all three on board as well as the driver of the second vehicle.

Mann said none of the injuries are considered life-threatening.

Acadian rushed two helicopters and several ground units to the scene of the wreck. Two people were airlifted to hospitals, Mann said, and the other two were taken away in ambulances.

Trooper First Class Bryan Lee, a Louisiana State Police spokesman, confirmed that troopers worked the crash involving the ambulance but said details about the wreck weren’t immediately available Sunday night.

Information about the condition of those injured in the wreck also wasn’t available Sunday night.
