HARRISBURG, Pa. - Pennsylvania transportation officials say the number of highway deaths in the state dropped to 1,208 last year.

PennDOT said Tuesday that represents the lowest figure since highway fatality records began to be collected in 1928.

Officials say there were declines over the previous year in the number of people who died not wearing seatbelts, the number of speed-related fatalities and the number of single-vehicle crashes in which the operator drove off the roadway.

Highway deaths in which a driver had been drinking fell from 377 in 2012 to 342 in 2013.

Deaths involving drivers over age 75, distracted drivers and head-on or opposite direction side swipe crashes all experienced increases last year.

PennDOT says it has spent $50 million in the past five years on safety improvements.

Locally, the York County Coroner's Office investigated 49 traffic-related deaths in 2013 compared to just 30 in 2012.

Of the 49 cases the office investigated, 47 of the deaths resulted from crashes that happened in York County. Two crashes happened outside the county, but the victims were transported to a hospital here where they died.

The coroner's office doesn't investigate cases of fatal York County crash victims pronounced dead at out-of-county hospitals.

Despite the increase, the total of 49 deaths remains below the 10-year average of 52 deaths annually.
