How the 3,000 lb threshold applies to three trailers
Minnesota measures gross weight, so the weight of the trailer as loaded is what counts.
| Example trailer | Weight checked | Against 3,000 lb |
|---|---|---|
| Small utility trailer | 1,650 lb | Under the Minnesota threshold by 1,350 lb |
| Loaded just under the line | 2,900 lb | Inside the Minnesota limit, but one heavy load away from crossing it |
| Mid-size travel trailer | 4,800 lb | Over the Minnesota threshold by 1,800 lb — brakes required |
