The best times to plow snow depend on the weather conditions, the amount of snow, and the type of area to be cleared. Generally, it is better to plow snow before it accumulates too much, as it will be easier and faster to remove. It is also better to plow snow during off-peak hours, such as early morning or late night, to avoid traffic and interference. However, some situations may require plowing snow during or after a storm, such as emergencies or heavy snowfall.
