When driving under limited visibility conditions, what should you do?

Using warning lights to increase visibility in limited visibility conditions is a critical practice for ensuring safety. Warning lights, such as those found on emergency vehicles, serve to alert other drivers and pedestrians to your presence, especially when visibility is compromised, such as during fog, rain, or nighttime driving. These lights help create a heightened awareness of the vehicle's location and actions, which is essential in preventing accidents.

Though reducing speed is a prudent approach, the primary mechanism in this scenario focuses on enhancing visibility rather than merely limiting speed. High beam headlights, while useful in some scenarios with low visibility, can be counterproductive in fog or heavy rain as they may reflect back and reduce overall visibility. Relying solely on street lights does not provide the same proactive measure that warning lights offer, as street lighting can be inconsistent or absent in certain areas. Hence, using warning lights effectively mitigates risks associated with driving in limited visibility.
