If you are bundling up to hit the road for Thanksgiving, be mindful of the dangers on a week when so many are traveling.
The National Safety Council projects that 433 people may be killed and another 49,400 may be seriously hurt in car accidents over the Thanksgiving holiday, which runs from Wednesday night to Sunday night.
Last year, Thanksgiving was the second deadliest holiday on the roads, the safety council said. The deadliest holiday was the Fourth of July.
The arctic blast is forecast to move through quickly, with temperatures returning to the low 50s on Sunday.
