To help relieve fatigue on a long trip, it is a good idea to:
- Stop and rest every two hours. ✓
- Do arm exercises every hour.
- Drive with one eye open at a time.
- Change feet on the gas pedal.
Answer: A. Stop and rest every two hours.
Stopping to rest every two hours is the right move; the handbook says to stop at least that often, or every 100 miles, even when you feel fine.
Why this is the answer
The handbook describes highway hypnosis, a drowsy, unaware state caused by reduced activity and the steady sound of wind, engine, and tires. To fight it, it tells drivers to stop often, at least every two hours or every 100 miles, get out, walk around, and let muscles relax. It also says not to drive more than eight hours a day. Resting like this breaks up the steady, low-activity stretch that brings on that drowsy state.
Why the other answers are wrong
- B. Do arm exercises every hour. — Arm exercises are not what the handbook recommends; it calls for getting out of the car and walking around, not doing exercises while driving.
- C. Drive with one eye open at a time. — Driving with one eye open at a time is not a rest method in the handbook, which talks about keeping your eyes moving and looking at near and far objects instead.
- D. Change feet on the gas pedal. — Changing feet on the gas pedal does nothing for drowsiness and is not mentioned anywhere in the handbook.
Remember it
Think of the clock and the odometer together: a stop roughly every two hours or every 100 miles, whichever comes first.
