When must headlights be turned on in South Dakota?

• A. Only in foggy conditions
• B. Between sunset and sunrise
• C. Any time the windshield wipers are in use
• D. During heavy rain only

Answer: (B)

Headlights in South Dakota must be turned on between sunset and sunrise to ensure visibility for both the driver and other road users. This requirement is part of safe driving practices, as it is crucial for drivers to be able to see the road clearly and for others to see their vehicle. While it is important to use headlights in various weather conditions and situations, the specific regulation states the necessity for headlights during the hours of darkness.

In addition to this rule, using headlights during other situations such as rain, fog, or when windshield wipers are in use is also encouraged to enhance safety, but they are not the only instances when they are required by law. Understanding these regulations helps to promote safer driving habits and compliance with state laws.
