The National Safety Council estimates that 308 people may be killed and 35,400 may be seriously injured in car crashes during the upcoming Christmas holiday period.

Additionally, the NSC expects as many as 356 fatalities and 40,900 injuries during the New Year's holiday period. The Christmas holiday period begins at 6 p.m. Friday, Dec. 22, and ends at 11:59 p.m. on Monday, Dec. 25. The New Year's holiday period begins at 6 p.m. on Friday, Dec. 29, and ends at 11:59 p.m. on Monday, Jan. 1, 2018.

With preventable deaths at an all-time high, the NSC said it's calling for states to take actions to reduce safety risks — particularly on roads.

“Safety is the greatest gift you can give, not only to your family but to those who share the roads with you,” said Deborah A.P. Hersman, president and CEO of the National Safety Council. “Buckling up, paying attention, slowing down and driving sober can ensure you and your fellow travelers make it home for the holidays.”

The NSC encourages states to take such measures as implementing sobriety checkpoints, requiring ignition interlocks for first-time and repeat DUI offenders, banning open containers, and automatically revoking licenses for more than 90 days for drivers with blood alcohol levels above .08 or those who refuse to test.

The National Safety Council also pointed out that impaired driving is a factor in more than 10,000 deaths annually, so drivers need to refrain from consuming alcohol or drugs prior to getting behind the wheel.
