Question: 1 / 400

When must drivers use their headlights in Iowa?

During the day only

From sunset to sunrise

In Iowa, drivers are required to use their headlights from sunset to sunrise to ensure visibility and safety while driving during low-light conditions. Utilizing headlights during these times helps illuminate the roadway and makes vehicles more visible to others, reducing the risk of accidents and enhancing overall roadway safety. It is a critical aspect of safe driving as reduced light can significantly impair a driver’s ability to see obstacles, pedestrians, or other vehicles.

Headlights are also a legal requirement during specific times beyond just nighttime, such as in conditions of reduced visibility due to weather conditions like rain, snow, or fog, emphasizing the importance of having them on when needed—even outside the specific hours from sunset to sunrise. This helps create a safer driving environment for everyone on the road.
