A commercial driver is operating a combination vehicle on a long, straight stretch of highway. To prevent 'highway hypnosis,' what conscious action should the driver take?
- AVary eye focus, frequently scan mirrors, and observe roadside activity.
- BIncrease speed slightly to maintain alertness.
- CEngage in a phone conversation to keep the mind active.
- DFocus intensely on the center line of the road.
Show answer & explanationAnswer & explanation
Correct answer: A. Vary eye focus, frequently scan mirrors, and observe roadside activity.
Highway hypnosis occurs when a driver stares straight ahead for long periods, leading to a trance-like state. Actively varying eye focus, constantly scanning mirrors, and observing the environment helps keep the brain engaged and prevents this dangerous condition.
Why the other options are wrong
- B. Increasing speed can exacerbate highway hypnosis by providing less time for mental processing and increasing risk.
- C. Engaging in a phone conversation is a major distraction and is illegal for commercial drivers, leading to impaired driving, not preventing hypnosis.
- D. Focusing intensely on the center line is a direct cause of highway hypnosis, as it leads to a fixed stare and reduced environmental awareness.
Preventing Highway Hypnosis
To prevent highway hypnosis, actively engage your mind by varying eye focus, scanning mirrors frequently, and observing the environment.
- Avoid fixed stare.
- Keep eyes moving.
- Take regular breaks.
Memory trick: Eyes on the move, no highway groove, stay alert, stay alive, that's the proof.
