An estimated 720 people may be killed on U.S. roadways during the upcoming holidays: 345 during the Christmas holiday driving period and an additional 375 during the New Year’s holiday driving period, according to the National Safety Council.

The nonprofit safety agency reports that impaired driving represents 36 percent and 40 percent of these fatalities, respectively.

In conjunction with the observance of National Impaired Driving Prevention Month, the National Safety Council calls on all road users to take safety personally this holiday season.

“Impairment, whether it be from alcohol, drugs and/or another factor such as fatigue or stress, causes a decline in visual function, mental judgment and motor skills,” said Mark Chung, executive vice president of roadway practice at the National Safety Council. “To save lives, we must all do our part by buckling up, driving sober (or arranging alternate transportation), slowing down, avoiding distractions and looking out for one another.”

More is being done to address the issue of impaired driving on U.S. roads.

Sobriety checkpoints are expected nationwide between Dec. 13 through Jan. 1.

In an effort to continue educating drivers throughout the holiday season, the National Highway Traffic Safety Administration is promoting public service messages through campaigns such as Drive Sober or Get Pulled Over and If You Feel Different, You Drive Different; Drive High, Get a DUI.

The Christmas holiday period begins at 6 p.m. Friday, Dec. 22 and ends at 11:59 p.m. Monday, Dec. 25. The New Year’s holiday period begins at 6 p.m. Friday, Dec. 29 and ends at 11:59 p.m. Monday, Jan. 1, 2024.
