JANESVILLE - Three teenagers were injured Saturday morning in a single-vehicle accident near Janesville.

Dreama Lancaster, 17, and Levi Wolfensperger, 15, both of Waverly and Samantha Sullivan, 16, of Mason City were all transported by ambulance to the Waverly Health Center for undisclosed injuries. Wolfensperger is a wrestler for Denver/Tripoli High School.

The accident occurred at 8:14 a.m. on Highway 218 at the intersection of 260th Street.

Lancaster was cited for failure to maintain control.
