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.
Stop and rest every two hours on a long trip.
Why this is the answer
The handbook says drowsy driving is as dangerous as drunk driving and that fatigue slows your thinking, hurts judgment and vision, and can cause you to nod off. Among its advice for avoiding drowsy driving is to take a break every 100 miles or 2 hours on long trips. Actually stopping to rest is what the handbook recommends, not in-car tricks.
Why the other answers are wrong
- B. Do arm exercises every hour. — The handbook does not suggest arm exercises as a remedy for fatigue; its advice is to take a break.
- C. Drive with one eye open at a time. — Driving with one eye open at a time is nowhere in the handbook and does nothing about the slowed reaction time and micro-sleeping it warns about.
- D. Change feet on the gas pedal. — Switching feet on the gas pedal is not mentioned in the handbook and does not address drowsiness, which the manual says calls for rest.
Remember it
Think in twos: every 2 hours or 100 miles, get out and take a real break.
