Texas Car / Permit practice question · Safe Driving Practices
To fight the drowsy, trance-like state that long highway trips can bring on, a driver should break the trip up:
Answer choices
- Only once they feel their eyes closing
- Roughly every two hours, or every 100 miles— Correct answer
- Once at the halfway point of the trip
- Every five hours, or every 300 miles
Why this is the answer
Highway hypnosis is drowsiness or unawareness brought on by steady wind, engine and tire sounds. To fight it, stop often, even when you feel well: at least every two hours or 100 miles. Get out and walk around to loosen your muscles. Waiting until your eyes are closing, or taking a single break halfway, is not enough.
