When visibility is less than 50 meters, what should a driver do?

When visibility is less than 50 meters, turning on the headlights is essential for both the driver’s safety and the safety of others on the road. Headlights illuminate the road ahead and make the vehicle more visible to other drivers, which is especially important in poor visibility conditions such as fog, heavy rain, or nighttime driving.

Proper use of headlights ensures that a driver can see obstacles, road signs, and other vehicles clearly, allowing for safer navigation through limited visibility. Additionally, having the headlights on helps other motorists become aware of the vehicle's presence, reducing the risk of collisions.

In this scenario, keeping headlights off or turning them off completely would compromise visibility for both the driver and others, while using fog lights is typically appropriate for specific conditions but may not suffice alone. Therefore, activating the headlights is the most effective measure to enhance visibility and ensure safety on the road in these circumstances.
