When is it necessary to use your headlights according to weather or light conditions?

Using your low beams is important in various weather or light conditions to ensure your visibility and the safety of others on the road. Low beams provide adequate illumination for nighttime driving and are designed to reduce glare for oncoming drivers. This makes them suitable for conditions such as rain, fog, or snow, where high beams can reflect off the precipitation, making visibility worse instead of better.

In situations with poor visibility due to weather, using low beams allows you to see the road safely while preventing light from blinding other drivers. It's essential to remember that there are specific regulations that require motorists to turn on their headlights during adverse weather conditions, such as rain or fog, to enhance visibility and alert other drivers to your presence.

The other options, such as using high beams, keeping headlights off, or only relying on parking lights, do not provide the necessary visibility and safety that low beams offer in these conditions.
