You plan a long drive across South Dakota on the interstate. To help prevent fatigue, how often should you plan to stop for a break?
Correct answer: About every 100 miles or every 2 hours
Why
Fatigue affects your vision and makes you slower to make decisions. Before the trip, get enough sleep; most people need 7 to 9 hours. If you feel tired on the road, leave the interstate at the next exit or rest area. A nap of 15 to 20 minutes can help, or you can stop for the night.
