What is the appropriate action if visibility is limited while driving?

When visibility is limited while driving, turning on your headlights is essential because it enhances your visibility and helps other drivers see you. Proper use of headlights is crucial during low-light conditions such as dusk, dawn, fog, rain, or when driving through tunnels. Having your headlights on allows you to see the road better and ensures that other vehicles are aware of your presence, decreasing the likelihood of accidents.

Using high beam headlights is not ideal in situations with limited visibility, as they can create glare for oncoming vehicles or be ineffective in fog and heavy rain. Speeding up is dangerous and does not address the root issue of poor visibility. Pulling over completely is a reasonable option when conditions are extreme, but in many situations, simply turning on your headlights is the immediate action drivers should take to maintain safety.
