Louisiana State troopers say they investigated 13 fatal crashes that resulted in 14 deaths over the Thanksgiving holiday.
Troopers said seven of the 14 people killed were not wearing seat belts and two of the crashes involved driver impairment.
Troopers are urging motorists to abide by the laws of driving sober and properly wearing seat belts.
According to the National Highway Traffic Safety Administration, in 2011, the national seat belt usage rate was 84 percent.
Louisiana was below that average at 77.7 percent. Louisiana law requires every occupant, regardless of seating position, to be properly restrained. Seat belts significantly reduce injuries and fatalities when worn properly and they ensure that the person remains inside the vehicle.
