What is the Illinois law regarding using headlights in low visibility conditions?

The correct answer highlights an important safety regulation in Illinois law that mandates the use of headlights during low visibility conditions. According to the law, when visibility is less than 500 feet, drivers are required to turn on their headlights. This requirement is in place to ensure that vehicles are visible to other drivers, which enhances safety for all road users.

Using headlights in low visibility conditions, such as heavy rain, fog, or nighttime driving, allows for better visibility of the vehicle and helps to illuminate the road ahead. It also ensures that other motorists can see a vehicle from a distance, reducing the risk of accidents.

This regulation underscores the importance of proactive safety measures while driving, encouraging drivers to be responsible and prepared for varying environmental conditions.
