Nothing is worse than arriving at Grandma's house on Thanksgiving Day filled with road rage because you just sat in traffic for hours.
So Google maps has compiled the data collected from Thanksgiving 2016 to let you know that the BEST time to leave your house if you want to avoid traffic is 6 a.m. on Thanksgiving Day.
The Thanksgiving Google Trends report also has an interactive tool where you can select your city, and then it will populate the best times to leave in order to avoid traffic. [Source]
