Traffic was backed up on the two-lane highway for about 40 minutes after the 5:51 p.m. crash.
Police said Summerly Lunz, 21, of Maryland was driving her Buick Skylark north on 120th Avenue when she failed to stop for the stop sign at M-45.
The Skylark struck an eastbound Honda Pilot driven by Carl Reid, 49, of Grand Rapids. Reid’s vehicle was forced across the centerline and sideswiped a Toyota Prius driven by Terry Berens, 51, of Grand Haven, police said.
The Prius went out of control and drove over some landscaping before spinning to a stop in the parking lot of the Yellow Jacket Restaurant on the northwest corner of the intersection, one witness said.
Berens and Lunz were transported by ambulance to North Ottawa Community Hospital. Reid and a passenger in his SUV — Elizabeth McCulloch, 43, also of Grand Rapids — were taken by Life Ambulance to Spectrum Butterworth Hospital in Grand Rapids.
All four people suffered non-life-threatening injuries, police said. Alcohol was not involved and everyone was wearing seat belts.
Kirk Loeffler, owner of the Yellow Jacket, watched the flurry of activity outside his business.
“This happens probably 3-4 times a year," said Loeffler, who has owned the restaurant for 23 years. “I don’t know what it’s going to be like when the new traffic starts coming through."
He was referring to an expected increase in traffic in the area once the new M-231 highway along the 120th Avenue corridor opens.
Loeffler said he hopes a traffic signal is installed at the intersection to cut down on the crashes.
Emergency personnel responding to the scene included Ottawa County Sheriff’s deputies, and Robinson and Grand Haven Township firefighters.
