Korean Driver's License Practice Test

Headlights should be turned on from a half hour before sunset until a half hour after sunrise to ensure maximum visibility during low-light conditions. This timeframe encompasses periods of twilight when natural light diminishes, making it crucial for drivers to use headlights to see the road clearly and make themselves visible to other road users. In these conditions, using headlights enhances safety as it allows for better visibility of obstacles, pedestrians, and other vehicles. While it may seem reasonable to use headlights only at night or in heavy traffic, these scenarios do not account for the importance of visibility during dawn and dusk, which can be equally hazardous. Clear weather conditions do not negate the need for headlights; instead, using them helps maintain safety during transitional lighting situations.
