Question: Last week, I noticed a truck with a snow plow blade on it. It took up the whole traffic lane. It was not a Minnesota Department of Transportation truck. What is the legal length allowed for a snow blade?
Troy Christianson
Answer: The maximum legal width is 8 feet 6 inches in Minnesota. Snow plows start at widths of 6 1/2 feet for smaller pickups and go up to 9- and 10-foot wide plows for dump trucks. The most common size plow is 7 feet and 6 inches. If you are over 8 feet 6 inches you can apply for a permit through the state. The permit will allow you to transport the plow on the roadway.
You can avoid a ticket — and a crash — if you simply buckle up, drive at safe speeds, pay attention and always drive sober. Help us drive Minnesota toward zero deaths.
