This number is up from 2016's holiday weekend, in which six people died in five crashes.
According to Michigan State Police, Charles Horn, 34, was driving on the highway around 11:00pm. Horn and his daughter, 15, are both listed in critical condition.
Of the 2017 crashes, four people who died were not wearing seatbelts.
Muscogee County Coroner Buddy Bryan said his office hasn't been officially notified of a death during the holiday but a man was injured seriously in a one-vehicle crash over the weekend and transported with life-threatening head injuries to a hospital.
These statistics cover only those crashes investigated by state police and do not include incidents to which other law-enforcement agencies in Pennsylvania responded.
Troopers also investigated two boating fatalities in Cleburne County, compared with zero boating fatalities for the previous year's holiday period.
The fatal accidents happened in Baldwin, Conecuh, Jefferson, and Tuscaloosa counties. This number is down from eight deaths over the same period in 2016.
Troopers are taking part in Click It or Ticket, a national campaign promoting the usage of seat belts, until June 4.
Troopers said they want to remind everyone to use seat belts no matter how short the trip, and to use PFDs on the water.
