DoD Allied Forces Italy (AFI) Driver's License Practice Exam

The correct answer stipulates that headlights must be turned on one half hour after sunset until one half hour before sunrise. This regulation is put in place to enhance visibility during times of reduced light, ensuring that drivers can see and be seen by others.

Driving during twilight or nighttime can present challenges due to lower light levels, and using headlights helps mitigate the risks associated with these conditions. The timeframe specified encompasses the hours when natural light is insufficient for safe driving, which is particularly important in urban areas where street lighting may not illuminate all roadways or pedestrian areas adequately.

In many regions, including those governed by the DoD Allied Forces Italy regulations, this practice is aimed at increasing safety for all road users, thereby reducing the likelihood of accidents. The specific mention of "one half hour" before and after key solar events reflects a widely accepted standard that balances visibility needs with practical considerations for when lighting conditions change.
