Final answer:
When encountering curves while driving at night, reduce speed for control, use headlights effectively while considering other drivers, and take note that external lights like moonlight are unlikely to cause significant vision impairment.
Step-by-step explanation:
When driving at night and you encounter curves, there are several things you have to remember. First, reduce your speed to maintain control and increase your reaction time, as it is harder to see the road ahead at night. Your headlights should be on and properly adjusted to illuminate the road without blinding other drivers. Remember that the ideal speed on a curve is the maximum safe speed at which a vehicle can turn without reliance on extra friction between the tire and the road. Using the high-beam headlights can improve visibility, but switch to low beams when other vehicles are approaching to avoid causing vision impairment. Finally, be aware that other lights, such as those from a full moon, are usually not intense enough to be blinding.
