"Northern Wisconsin Implements Frozen Road Laws: What You Need to Know"

The Wisconsin frozen road law is set to begin on Thursday for the northern half of the state, affecting Zone 1 and Zone 2, allowing vehicles hauling abrasives or salt for highway winter maintenance and certain forest products to carry more weight. The declaration is issued once the ground under highway pavement is frozen to a depth of at least 18 inches, and special permits for hauling the increased weights are not required in Zone 1 and Zone 2. However, the higher weight limits do not apply to county or local roads unless authorized by the local agency having maintenance authority.
