This is a test of commonsense. Complete the next sentence:

How to be comfortable on a long car trip
Plan breaks.
Map the route your trip will take ahead of time, being sure to build in stops every couple of hours. Taking a break gives you the opportunity to stretch and walk around.
It will also keep your legs from cramping up! You should plan your stops at places with bathrooms, so you don't have to frantically search for one when you need one. Get lots of rest before your trip.
