Which of these is a safe driving technique?

To stay aware of hazards, you should scan the road and check your rearview mirrors every two to five seconds. Constantly staring at just the road ahead of you is dangerous. If you must drive in foggy conditions, you should use your low beam headlights, not your high beam headlights.

• Using your high beam lights in the fog.
• Staring at the road ahead of your vehicle.
• Checking your rearview mirrors frequently.
