Adjusting your speed so you can stop within the distance illuminated by your headlights is a critical safety measure when driving at night or in low visibility conditions. If your headlights allow you to see only 250 feet ahead, it is vital to ensure that your stopping distance is not greater than what you can see. This means that if you encounter an unexpected obstacle or situation within that distance, you will have sufficient time to react and stop safely.

The correct approach emphasizes the importance of being able to respond to hazards effectively. Common factors like road conditions, vehicle load, and braking ability will all influence your stopping distance, but by managing your speed to align with your visibility range, you are taking a proactive step to enhance your safety on the road. This practice is crucial for preventing accidents and ensuring that you can navigate safely, especially when visibility is limited.
