Hilliard resident Pam Saraniero didn’t realize she had to yield to cars in both lanes of the roundabout, and learned the hard way. In January, she said she saw a Ford Escape moving in the inner lane as she approached the roundabout. Then she drove into the circle, hitting the Escape and knocking the front bumper off her Honda Accord.

In hindsight, she said she wrongly assumed the other driver would loop around the roundabout rather than exit across her path.

“It was my fault, absolutely,” the 67-year-old retiree said.

Jane Wahl, who also crashed there in January, said approaching drivers often race into the roundabout. “Not everybody has the same attitude about what the rules are in these roundabouts,” she said.
