Just for fun I typed in "Deadliest Travel Day of the year" on Google and these were the first 3 websites:

"July Fourth Traffic and the Deadliest Travel Day on the Highway"

"Thanksgiving is Deadliest Travel Day : Insurance Resources"

"Christmas Day is Deadliest of the Year, Says 26-Year Study"


Of course everyone should be careful, any time there are a number of people on the road and alcohol is consumed its a dangerous time.
