When should headlights be turned on?

Headlights should be turned on in both dark conditions and when visibility is low, such as during rain or fog. This practice enhances safety by ensuring that your vehicle is visible to others and that you can see the road ahead clearly. In complete darkness, headlights allow you to navigate the roadway while making your vehicle apparent to other drivers, pedestrians, and cyclists.

In conditions of reduced visibility, like rain or fog, using headlights can help cut through the weather elements, allowing for better sightlines and making your vehicle more noticeable. Low-beam headlights are particularly effective in fog as high beams can reflect off the fog and create glare.

By turning on your headlights in these circumstances, you are following safe driving practices that contribute to overall road safety. Therefore, the correct answer encompasses both situations where headlights are essential for safe driving.
