A Pima County sheriff's deputy was involved in a traffic crash Monday on the Tohono O'odham Indian Reservation.

Five of six occupants of the other vehicle involved were hurt, but none had life-threatening injuries. They were taken by ambulance or helicopter to a hospital, according to a news release from the Sheriff's Department.

Just before 5 p.m. Monday, Deputy John Weeks was eastbound on Arizona 86 on the reservation southwest of Tucson when he approached a line of traffic traveling below the 55 mph speed limit.

Weeks checked for oncoming traffic and moved into the opposing lane to pass the vehicles. As he was passing, the lead vehicle in the line made a U-turn in front of Weeks' vehicle.

The deputy's vehicle collided with the driver's door of the other vehicle.

Weeks was not injured.

The Tohono O'odham Police Department is conducting the investigation.
