Yep, make sure and get a GPS programed to your destination and then travel at your own pace. Your health and safety comes first. The 'authorities' suggest stopping every two hours and getting out and walking around. And this is for the average person, not one who has had a new tkr! If you get separated from your other family members you'll have the directions, and hopefully a phone with you to keep in contact with each other. Ice packs are a good idea, too.
