Illinois Driving Permit Practice Test

When are you required to use your car’s headlights?

1. Only at night

2. From sunset to sunrise

3. From sunset to sunrise and anytime visibility is less than 500 feet

4. During inclement weather only

The correct answer is: From sunset to sunrise and anytime visibility is less than 500 feet

Using your car's headlights is essential for ensuring visibility and safety on the road. The requirement to use headlights from sunset to sunrise applies because these times are typically associated with reduced lighting conditions, making it difficult for drivers to see and be seen by others. Additionally, headlights must be used anytime visibility is less than 500 feet, which includes various situations such as fog, heavy rain, or snow where your ability to see the road clearly is compromised. This rule is designed to enhance safety for all road users, as it allows drivers to see obstacles and other vehicles better while also ensuring that their own vehicle is visible to others. While headlights are not exclusively required at night, they play a crucial role in any low-visibility situation, reinforcing the importance of understanding the correct times and circumstances to use them.
