What is the safe following distance on highways during snowy conditions?

[Everett]

When driving on highways during snowy conditions, the increased rolling resistance on snow-covered roads and the obscured road surface make it difficult for drivers to discern directions. It is essential to adjust your speed and maintain a safe following distance based on visibility. Below are the recommended guidelines based on visibility levels: 1. When visibility is less than 200 meters: Speed should not exceed 60 km/h, and maintain a distance of at least 100 meters from the vehicle ahead in the same lane; 2. When visibility is less than 100 meters: Speed should not exceed 40 km/h, and maintain a distance of at least 50 meters from the vehicle ahead in the same lane; 3. When visibility is less than 50 meters: Speed should not exceed 20 km/h, and exit the highway at the nearest available exit as soon as possible.
