The crash happened Friday afternoon on 120th Avenue, near Lincoln Street in Robinson Township.
Deputies said a 20-year-old woman driving a white Kia took off her seat belt to grab a water bottle that had fallen onto the floor. That's when her car veered and crashed into an Ottawa County Road Commission street sweeper driven by a 60-year-old man.
Both drivers were conscious as they were taken to a nearby hospital with injuries. Their names and conditions were not immediately known.
Police temporarily closed a portion of 120th Avenue for investigation and cleanup.
