How often are snow plows required to stop to let other vehicles pass?

The correct answer is that snow plows are required to stop to let other vehicles pass every 5 miles. This regulation is in place to ensure safety on the roads during winter weather conditions when visibility may be reduced, and travel can become more challenging due to snow buildup. By stopping periodically, snow plows allow other vehicles the opportunity to pass, reducing traffic congestion and enhancing overall roadway safety.

While options that suggest greater distances, such as 10 miles or 20 miles, would not be practical in maintaining the flow of traffic, especially in heavy snow, the 5-mile requirement strikes a balance between effective snow removal and allowing other drivers to navigate the roads safely.
