In addition, troopers issued 13,935 speeding citations, cited 1,222 individuals for not wearing seat belts, and issued citations to 289 motorists for not securing children in safety seats.

A report by the National Safety Council estimated that 439 Americans would be killed this past weekend, the highest number since 2009. Experts believe the main reason Memorial Day weekend is so deadly is because there is more people on the road. And more drivers mean more traffic fatalities.

The statistics cover only those crashes investigated by state police and do not include statistics on incidents to which other law-enforcement agencies in Pennsylvania responded.
