Illinois Driving Permit Practice Test

When should headlights be used while driving?

1. Only at night

2. Whenever visibility is poor

3. Only in urban areas

4. During daylight hours

The correct answer is: Whenever visibility is poor

Using headlights whenever visibility is poor is essential for ensuring safety while driving. This includes situations where weather conditions, such as rain, fog, or snow, reduce your ability to see clearly, as well as times when it is dark, such as at night. Poor visibility can not only make it difficult to see the road and other vehicles but also hinders other drivers’ ability to see you. Therefore, using headlights in these conditions is mandated by traffic laws to enhance overall safety on the road. The other options do not fully address the importance of using headlights in a comprehensive manner: while headlights are indeed necessary at night, they should also be used in any situation where visibility is compromised, not just limited to urban areas or only in daylight. Thus, the correct approach is to use headlights whenever visibility is poor, regardless of the time of day or location.
