Nov. 14, 2018—The National Safety Council estimates 433 people may be killed and another 49,400 may be seriously injured in car crashes during the upcoming Thanksgiving Day holiday period.

The Council is urging additional caution because in 2017, Thanksgiving was the second deadliest holiday on the roads, trailing only the Fourth of July.

The NSC State of Safety report encourages states to implement proven measures to help reduce risk including instituting sobriety checkpoints, requiring ignition interlocks for first-time and repeat offenders, banning open containers, or automatically revoking licenses for more than 90 days for drivers with BAC levels above .08 or those who refuse to test.

Historical trends show that on average, more than one-third of deaths during the Thanksgiving holiday period involve alcohol-impaired drivers. The Council is warning drivers to be particularly vigilant at the start of the holiday period, which runs from 6 p.m. Wednesday, Nov. 21 to 11:59 p.m. Sunday, Nov. 25.
