When driving on a highway at night, you should never use your high-beam headlights if you are:

1. Approaching or following another vehicle: Using high-beams can blind the driver ahead of you, which could lead to dangerous situations.

2. In foggy, rainy, or snowy conditions: High beams can reflect off precipitation, causing glare and making it hard to see the road ahead.

3. In well-lit areas: If you are driving in areas with streetlights or other forms of illumination, it is courteous and safer to use low beams.

4. When there is oncoming traffic: High beams can hinder the visibility of drivers approaching from the opposite direction, increasing the risk of accidents.

It's crucial to be considerate of other drivers on the road and to ensure your visibility does not compromise their safety. Always switch to low beams in these scenarios to promote safer driving conditions for everyone.
