Police said non of the injuries appeared to be life-threatening.
Emergency crews responded to the rural intersection at about 2:42 p.m.
Witness Anna Hoover said that she was driving behind the car, when it suddenly turned in front of the mini-van.
Police said the van was traveling west and the car was headed east, when the driver of the car attempted to turn north onto Forest Park Drive in front of the van. The vehicles collided and the car left the road and went into the ditch.
“She thought she had more time,” Hoover said after talking to the driver of the car.
Ottawa County Sheriff’s deputies and Grand Haven Township firefighters, assisted by officers from the Grand Haven Department of Public Safety worked the scene.
Firefighters extricated the occupants of the car, who were pinned inside the vehicle after the crash.
Life and North Ottawa Community Hospital paramedics attended the injured, and then transported all of them to area hospitals.
Hoover said a teenage girl was driving the car that was also occupied by her mother and great-grandparents. They were on the way to a family party, Hoover said.
The driver of the Toyota Corolla, a 15-year-old Caledonia girl, was learning to drive, said Sgt. Brian Buter of the Ottawa County Sheriff’s Office. Her 43-year-old mother was sitting in the front passenger seat. The girl’s great grandparents, ages 89 and 92, both of Holland, were in the back seat. They were all wearing their seatbelts.
The driver of the white Chrysler Town & Country mini-van was a 42-year-old Grand Rapids woman. She was also wearing her seatbelt, Buter said.
The driver of the van was also transported to an area hospital. Two dogs in her vehicle were OK.
Buter said the injured people were taken to Grand Haven and Muskegon-area hospitals.
The crash is still under investigation.
