What are typical signs of driver fatigue?

• A. Increased alertness and faster reaction times.
• B. Daydreaming, yawning, drifting, slower reaction times; stop and rest.
• C. Constantly maintaining perfect lane position.
• D. Never feeling tired regardless of duration.

Answer: (B)

Fatigue slows your awareness and reaction time, so you’ll notice warning signs that you’re getting tired while driving. Typical signs include daydreaming or drifting attention away from the road, yawning, and slower, less reliable reactions to braking or steering. You might also drift out of your lane because your mind isn’t fully focused on the drive. When you notice these signs, the safest move is to stop somewhere safe and rest before continuing.

Other descriptions don’t fit fatigue as well. Increased alertness and faster reaction times would indicate you’re not fatigued, while constantly maintaining a perfect lane position is unlikely when tired. Feeling never tired is unrealistic for any long drive.
