Is it mandatory to use headlights if windshield wipers are on due to bad weather?

Using headlights while windshield wipers are in operation is a legal requirement in many regions, especially when visibility is poor due to bad weather such as rain, snow, or fog. Headlights help ensure that other drivers can see your vehicle under these conditions, thus enhancing safety for everyone on the road.

When windshield wipers are activated due to inadequate visibility from rain or other weather conditions, it is typically mandatory to also have your headlights on. This is because the wipers indicate that the weather is affecting visibility, and using headlights enhances visibility for both the driver and other road users.

In contrast, considering that it is optional based on personal judgment or only necessary during severe thunderstorms undermines the principle of driving safely in all adverse weather conditions. Regulations governing headlights in relation to wipers being on underscore the importance of maintaining visibility and ensuring safety at all times when visibility is compromised.
