When should headlights be turned on while driving?

Turning on headlights in adverse weather conditions is essential for visibility and safety. Conditions such as rain, fog, snow, or heavy overcast create situations where visibility can be severely impaired; therefore, using headlights helps both the driver to see better and allows others on the road to see the vehicle. This practice is not only a matter of improved visibility but is often a legal requirement in many areas during such conditions.

While headlights are typically required at night to ensure the driver can see the road ahead, relying solely on headlights during nighttime does not encompass other necessary situations where visibility challenges arise. Although headlights are recommended at all times for safety and improved visibility, in adverse weather conditions, their use becomes critical. Similarly, while headlights should be used when driving through tunnels due to often reduced lighting, these specific situations exemplify the necessity of their use in wider adverse conditions.
