To prevent drowsiness during continuous driving on an interstate road, drivers should:

• A. Keep shifting their eyes
• B. Sleep with sunglasses on
• C. Increase following distance to 3 seconds
• D. Listen to loud music

Answer: (A)

Staying alert on long, straight stretches comes from actively scanning the road rather than letting your gaze settle. Shifting your eyes and looking around—far ahead, to the sides, and checking mirrors—keeps the brain engaged and helps you notice hazards sooner. This routine breaks the monotony that can lead to drowsiness and maintains situational awareness, which is essential for safe interstate driving.

Increasing following distance, while useful for giving you more time to react, doesn’t directly prevent fatigue. Sleeping with sunglasses won’t restore alertness and reduces visibility. Loud music might wake you briefly, but it can be distracting and isn’t a reliable way to prevent drowsiness. If you start feeling sleepy, the safest option is to take a break and rest.
