What is the rule regarding headlights when driving in bad weather?

Using headlights during poor visibility conditions, such as rain, fog, or snow, is essential for safety. This rule ensures that drivers can see the road clearly and that their vehicle is visible to others. Headlights enhance visibility in adverse weather conditions and significantly reduce the risk of accidents by making vehicles more conspicuous to other drivers and pedestrians.

In situations where visibility is compromised, such as heavy rain or fog, not using headlights may lead to dangerous driving conditions. It's important to note that using high beams in fog, for instance, can actually create glare and reduce visibility further, which is why headlights should be on low beam. Therefore, adhering to the rule of using headlights in poor visibility helps create a safer driving environment for everyone on the road.
