What is a key factor to consider when driving in foggy conditions?

When driving in foggy conditions, reducing speed and increasing your following distance is critical for safety. Fog can significantly impair visibility, making it difficult to see other vehicles, road signs, and potential hazards. By slowing down, you give yourself more time to react to unforeseen circumstances, such as a vehicle or pedestrian suddenly appearing in your path.

Additionally, increasing your following distance allows more space between you and the vehicle in front, which is essential in case the driver ahead has to stop unexpectedly. This extra distance helps prevent collisions and allows you to maintain control of your vehicle in low visibility situations.

Using high beam headlights is not advisable because they can reflect off the fog, creating a glare that actually reduces visibility further. Driving over the speed limit is dangerous and irresponsible, especially in conditions where visibility is compromised. Lastly, frequently using the horn is not a recommended practice in fog; it does not enhance safety and can distract other drivers or create confusion, rather than help in communication during low visibility.
