Why Does the Distance Between Vehicles Decrease as Visibility Decreases?

[Marcus]

If the distance is too far, the driver cannot see the vehicle in front; only when the distance is close can the driver see it, thus making the distance seem shorter. Distance restrictions in foggy weather: When visibility is below 200 meters, the distance from the vehicle in front should be maintained at more than 100 meters. If visibility is below 100 meters, a distance of over 50 meters should be maintained. If visibility is below 50 meters, a distance of more than 50 meters should be maintained. However, since vehicles beyond 50 meters cannot be seen under such conditions, it is necessary to drive to a safe location and park as soon as possible, waiting for the weather conditions to improve before continuing. Precautions for low visibility: When driving in fog, turn on the fog lights and hazard lights, as well as the side marker lights. If visibility is below 50 meters, the speed should be controlled within 20 kilometers per hour. Under such conditions, it is necessary to exit the highway at the nearest possible location.
