What is the best practice regarding headlights in bad weather?

Turning on headlights during bad weather is crucial for enhancing visibility for both the driver and other road users. In conditions such as rain, fog, or heavy snow, the illumination provided by headlights helps to improve the driver's view of the road and also allows other drivers and pedestrians to see the vehicle more easily.

In many regions, traffic laws require drivers to use headlights during inclement weather. This is not just a matter of convenience; it is a safety measure designed to reduce the risk of accidents that can occur when visibility is compromised.

Using high beams, while they may initially seem like a good way to improve visibility, can actually cause glare that impairs the vision of other drivers in adverse conditions, such as fog or rain. Similarly, keeping headlights off to save energy not only reduces visibility but also increases the likelihood of collisions. Using headlights only at nighttime neglects the safety protocols necessary for driving during daylight hours when weather impacts visibility. Thus, the recommended best practice is to always turn on headlights in bad weather to ensure the safety of everyone on the road.
