The driver, Sean Rehmann, 24, of Garnet Valley, was unable to stand when a responding officer tried to administer a sobriety test Tuesday, Upper Darby Police Superintendent Michael Chitwood said. The passenger, Laura Popielarski, 34, of Clifton Heights, refused to allow herself or her daughters, 8 months and 4 years old, to be evaluated at a hospital for injuries but was ordered to a hospital by police, Chitwood said.
