Essential Minnesota Trailer Towing Laws: What You Need to Know Before You Tow

If you’re towing a trailer in Minnesota, whether for a weekend camping trip or transporting equipment for work, it’s essential to understand Minnesota Trailer Towing Laws and the specific state regulations for trailer towing. Minnesota has its own set of towing laws designed to ensure safety on the roads, protect drivers, and prevent accidents. Here’s an overview of the key requirements you’ll want to be aware of before you hitch up and hit the road.

1. Trailer Weight and Licensing Requirements

In Minnesota, the Gross Vehicle Weight Rating (GVWR) of a trailer affects what type of license you may need. For trailers over 3,000 pounds, a special endorsement may be required on your driver’s license. If your trailer’s GVWR is under 3,000 pounds, you’re typically in the clear without an endorsement, but you should still ensure that your towing setup meets all safety requirements.

2. Trailer Brakes and Safety Chains

Minnesota requires trailers over 3,000 pounds to have brakes on all wheels. This braking system must also be able to automatically engage and stop the trailer should it become detached from the towing vehicle. In addition, Minnesota law mandates the use of safety chains to secure your trailer to your towing vehicle. These chains act as a backup connection if the main hitch fails, keeping your trailer connected to your vehicle and minimizing the risk of a runaway trailer.

3. Lighting and Reflectors

Minnesota requires trailers to have proper lighting, including taillights, brake lights, license plate lights, and turn signals. Reflectors are also essential to ensure visibility for other drivers, particularly at night or in poor weather conditions. This equipment must be functional and positioned to clearly indicate your trailer’s presence, length, and width.

4. Maximum Towing Speeds

In Minnesota, the posted speed limits generally apply to vehicles towing trailers as well. However, it’s advised that drivers towing a trailer stay at lower speeds to maintain better control. Reducing your speed, especially in adverse weather or heavy traffic, can make your towing experience safer and less stressful.

5. Load Securing and Distribution

Under Minnesota law, any cargo in or on a trailer must be properly secured to prevent items from shifting or falling onto the road. This rule is particularly strict when towing open trailers where cargo is exposed. Additionally, be mindful of load distribution: unevenly distributed weight can cause swaying, making the trailer difficult to control. Aim for about 60% of the weight at the front half of the trailer to ensure stability.

6. Towing Multiple Trailers

Minnesota law permits towing more than one trailer, provided that the first trailer has a fifth wheel or gooseneck hitch. However, it’s essential to consult state guidelines and consider your vehicle’s towing capacity before attempting to tow multiple trailers. In most cases, the total length of all vehicles and trailers combined should not exceed 70 feet.

7. Mirror Requirements

If your trailer blocks the rearview mirror of your towing vehicle, Minnesota requires the use of side mirrors that provide a clear view of the road behind you. These mirrors help you remain aware of other drivers and ensure you’re able to navigate safely while towing.

Final Tips for Safe Towing in Minnesota

Before you begin any trip, conduct a quick pre-trip inspection. Check the trailer’s connection, ensure all lights are working, test the brakes, and confirm the cargo is secure. Proper preparation can help you avoid accidents and comply with Minnesota’s trailer towing laws.
