Understanding Frost Laws: What You Need to Know

Winter is coming, and with the colder weather both shippers and carriers need to prepare for the impact that Frost Laws might have on their freight shipping.

What are Frost Laws?

Frost Laws, or seasonal weight restrictions, are put in place on specific roads to safeguard them from damage during thaw and freeze cycles. These rules differ by region and usually control the weight and speed of vehicles, ensuring the preservation of road infrastructure. Seasonal weight restrictions typically begin in early March, persisting through mid-June. With conditions varying annually, states and provinces retain the authority to adjust spring load restrictions based on observed ever-changing weather factors. These adjustments are crucial for determining the specific dates for implementing and lifting weight restrictions. For example, Michigan Frost Laws can vary county to county due to the northern regions being subjected to harsher weather conditions than the southern part of the state.

Impact on Heavy Haul Freight

For heavy haul freight, Frost Laws can be a logistical puzzle. With weight restrictions and specified routes, your operations will face disruptions during this time. In fact, 16 states in the US have enacted Frost Laws, creating a lot of nuances between different regulations to navigate. These states include:

• Idaho
• Iowa
• Maine
• Michigan
• Minnesota
• Montana
• Nevada
• New Hampshire
• New York
• North Dakota
• Pennsylvania
• South Dakota
• Vermont
• Washington
• Wisconsin
• Wyoming

Compliance and Consequences

Failure to comply with Frost Laws can result in substantial fines and damage to your truck, trailer and cargo. However, adhering to these regulations can significantly reduce road maintenance costs. By understanding and following Frost Laws, you’re not only protecting your bottom line, but also contributing to safer and more sustainable transportation infrastructure for everyone else.

Strategies for Success

Staying informed about state-specific Frost Laws is crucial. When moving freight in the northern regions from February to May, expect your load to face some impact. Weight restrictions factor in axle weight and gross weight, so even legal loads as light as 40,000 pounds could encounter hurdles. By proactively adjusting your routes and leveraging innovative technology, you can ensure compliance with these regulations and keep your heavy haul freight operations rolling without a hitch.
