How Oregon Allows Divisible Loads Up to 105,500 lbs

April 30, 2026, 6:22 p.m.
Oregon is one of the few states that permits divisible loads (loads that can normally be broken down) to exceed the standard 80,000 lb federal limit—up to 105,500 lbs—through its Extended Weight Annual Permit program.

1. Special State Program (Not Standard Federal Rules)

Under federal law, most states limit divisible loads to 80,000 lbs gross vehicle weight.

However, Oregon uses a state-authorized exception system that allows higher weights through:

  • Annual extended weight permits
  • State-controlled highway systems
  • Engineering-based weight tables

 This means the higher weight is legal only within Oregon and under specific conditions.

 2. Extended Weight Annual Permit

To operate up to 105,500 lbs, carriers must obtain an:

 Oregon Extended Weight Annual Permit (Divisible Loads)

This permit:

  • Authorizes year-round operation
  • Applies to specific truck and trailer configurations
  • Eliminates the need for repeated trip permits

 3. Strict Axle & Configuration Requirements

You don’t automatically get 105,500 lbs—your truck must be built for it.

Approval depends on:

  • Number of axles (typically 7–9 axles or more)
  • Axle spacing
  • Tire ratings and suspension
  • Compliance with Oregon’s weight tables (Table 1–4 system)

 The more axles and better spacing, the higher the allowable weight.
