Final answer:
Three preventative measures to consider when driving at night are: using headlights on low beam, reducing speed and increasing following distance, and avoiding looking directly at oncoming headlights.
Step-by-step explanation:
When driving at night, there are several preventative measures to consider:
- Use headlights on low beam: This helps reduce the glare for both you and oncoming drivers.
- Reduce speed and increase following distance: Nighttime visibility is reduced, so it's important to give yourself more time and space to react to any potential hazards.
- Avoid looking directly at oncoming headlights: The bright light can temporarily impair your vision and make it difficult to see the road ahead.
By following these measures, you can help improve your safety while driving at night.
