Senate File No. 820 proposes changes to Minnesota's transportation laws regarding the maximum allowable gross weight of vehicles on state roads. The key points of this bill include:

1. Increased Weight Limit: It proposes to raise the maximum gross vehicle weight limit to 108,000 pounds from the current limit, offering more leeway for heavier vehicles without requiring special permits.

2. Taxation Adjustments: Adjustments to the tax rates for truck tractors and combinations are specified. These rates will be graduated based on gross weight, with additional taxes imposed for weights exceeding 80,000 to 108,000 pounds.

3. Permit Eliminations: The bill aims to simplify regulations by dispensing with the need for various special hauling and overweight permits.

4. Amendments and Repeals: Several statutory sections regarding vehicle weight and permits will be amended for consistency with the new weight limits, and various other regulations will be repealed.

Essentially, this bill modifies existing laws to allow heavier vehicles on public roads without special permits, adjusts related taxes, and eliminates some regulatory requirements. This is intended to streamline transportation regulations in a manner that can support heavier hauls, potentially benefiting industries that rely on road transport.
