The department said a 24-year-old Hudson, New Hampshire woman was pulled over after other drivers reported she was swerving across lanes.
But it was the gas station nozzle, still attached to her Range Rover, that first caught their attention.
"We were able to return the gas nozzle to its rightful owner," the department wrote.
The woman was charged with OUI liquor, negligent operation, and an open container violation.
Wilmington Police thanked the other drivers who reported the woman.
