The average family will spend more than seven-and-a-half hours in the car together traveling over the holidays.  They're definitely going to FIGHT.

A new survey found that most families KNOW they're going to have road trip fights . . . and more than a quarter of them start arguing within an HOUR of getting in the car.

Here are the top five most common things people fight about on family road trips:

#1.)  Backseat driving and/or the driver's driving style.

#2.)  Children arguing.

#3.)  What to listen to after you're too far from K102.

#4.)  Which way to go.

#5.)  Kids asking "Are we there yet?"
