A passenger broke his shoulder when the driver fell asleep at the wheel and rolled her vehicle over on Route 1 in Littleton, Wednesday.

The Aroostook County Sheriff’s Office said Michaela Gray also hit a tree in the crash after the 2005 Subaru drifted off the road.

Robin Witham of Hodgdon was taken to Houlton Regional Hospital. Gray declined medical treatment, said Chief Deputy Shawn Gillen.
