INDIANAPOLIS — The Indiana Department of Transportation and Indiana Department of Revenue published new permit rules and fees for overweight vehicles hauling metal and agricultural commodities over state highways from the farm, a mill or storage to market for further processing.

The permit rules are more consistent with neighboring states and with the infrastructure resources being consumed.

The permit rules govern loads of metal coils, rods and plates up to 120,000 pounds and agricultural loads including corn, beans, wheat, oats and bulk milk up to 97,000 pounds. The rules do not include items used in production of these commodities, such as ore, scrap metal, seed or fertilizer.

The overweight loads must meet other requirements for height, length and width, and portions of trips over city, town or county roads must be permitted separately through local governments.

The permits will be calculated using Equivalent Single Axle Load Miles, a unit that measures various types of configurations with a single number. For example, an 80,000-pound, 5-axle tractor trailer that may travel state highways without a permit is measured at about 2.4 ESALs.

All metal and agricultural commodities exceeding 80,000 pounds require permits and will be charged for additional ESALs greater than 2.4. The additional ESALs will be multiplied by 7 cents for every mile the load will travel, plus a $20 administrative fee.

Revenue from the new fees will be credited to the state highway fund for maintenance and reconstruction of state roads and bridges.

During the first quarter of 2014, the revenue department plans to offer an annual multi-trip permit for trucks that exceed 80,000 pounds, but due to additional axles, remain at or under 2.4 ESALs.

The rules include new limits on axle weight and spacing to help preserve Indiana’s bridges and pavement.

To ensure safety and mobility, the truck must be capable of pulling the permitted load, and each axle must have functional brakes rated by the manufacturer for load at or above the permitted axle loads.

The rule includes progressive suspensions of new permits for repeat violations.
