Sally Derdaele, 70, was northbound on Beacon and was moving into the turn lane about 2:30 p.m. when her Audi convertible was rear-ended, police said.
Her car spun around into the median and ended up facing northbound against a traffic sign.
She suffered minor injuries and headed to North Ottawa Community Hospital as a precautionary measure, officials said.
An 18-year-old Grand Haven man said he was also northbound. He was returning to a nearby pizza business after making a delivery.
He said he momentarily closed his eyes, but did not know what happened when the collision occurred.
His Cadillac went up into the median and knocked down a speed limit sign, before ending back in the travel lane.
He was not injured.
