Final answer:
To deal with oncoming headlights that are too bright, avoid direct eye contact with the light, glance to the right using the white line as a reference, and ensure your windshield is clean to minimize glare. Adjust your mirrors or use a mirror's night setting as needed, and do not flash your high beams in response.
Step-by-step explanation:
When you encounter headlights from an oncoming vehicle that are too bright, the safest action is to avoid looking directly at the light. Instead, shift your gaze to the right side of your lane and use the white line on the road (or the road's edge) as a guide for your peripheral vision. This technique helps to reduce the glare affecting your vision. Do not attempt to retaliate by flashing your high beams, as this can worsen the situation for both drivers. It's also crucial to ensure that your windshield is clean, both inside and out, as dirt or streaks can amplify the glare. If the problem persists, you should consider adjusting your vehicle's mirrors or using the night setting on the rearview mirror to diminish the reflected light from vehicles behind you. Remember never to look at very bright light directly, as it can damage your eyes.
