HARRISBURG - Traffic fatalities in the commonwealth over the Christmas holiday fell by half from last year, according to the Pennsylvania State Police.

From Dec. 24 to 27, police said, four people died in vehicle crashes, including one that was alcohol-related. The crashes occurred in Erie, Indiana, Lancaster and Lehigh counties.

Last year, eight were killed and 224 injured over the holiday and subsequent weekend.

Of the 632 crashes reported this year, 54 involved alcohol, police said.

Troopers arrested 218 people for driving under the influence and gave out 2,677 speeding tickets and 297 seat-belt violations.

Three out of the four who died this year were not wearing seat belts, police said.
