Oversize/Overweight (OSW)

OSW General Information

Indiana law states that drivers must obtain an oversize and/or overweight vehicle permit before traveling on Indiana roads if their vehicle exceeds:

  • 13 feet 6 inches in height
  • 8 feet 6 inches in width
  • 53 feet (semi-tractor-semi-trailer combination) in length; or
  • 80,000 pounds gross vehicle weight (subject to axle weights)

Two-vehicle combinations totaling 60 feet or more are not eligible for OSW permits unless the vehicle is registered as a tractor trailer or one of the vehicles is a fifth-wheel travel trailer.

Most Indiana OSW permits are issued by the Indiana Department of Revenue's Motor Carrier Services (MCS) department, under the guidance and rules set by INDOT and in accordance with Indiana law. The Oversize/Overweight (OSW) unit at MCS helps drivers make these loads non-divisible and properly marked to ensure the safety of all motorists. Also, MCS issues and collects civil penalties for OSW violations issued by Indiana State Police.

In addition to obtaining a permit, drivers must follow signage, escort and other requirements. In some cases, loads are required to have an Indiana State Police escort. Requirements are listed on M-204, General Provisions of an Oversize/Overweight Vehicle Permit and M-204S, Special Provisions for Vehicle Permitting. A paper or electronic copy of the M-204 and, if applicable, the M-204S, must be kept with the OSW permit.

Farm vehicles that meet the dimensions listed above and travel on any interstate in Indiana need an OSW permit. Farm vehicles are not exempt from escort requirements on secondary roads. For more information on escort requirements, see Form M-204, General Provisions of an Oversize/Overweight Vehicle Permit.

Indiana HEA 1190, which takes effect July 1, contained several changes to Indiana’s oversize/overweight (OSW) motor carrier laws, including expanding Indiana’s Overweight Commodity Permit to include materials other than metal and agricultural products.

Under the new law, carriers can apply for a single-trip Overweight Commodity permits for divisible loads exceeding 2.4 ESALs and weighing 80,000-120,000 lbs. Although the law allows only 8500 of these permits annually, there are no limits on the number of annual permits issued for divisible loads less than 2.4 ESALs.

Carriers who obtained an OSW Commodity Permit prior to Jan. 1, 2021 are grandfathered into the new law in certain circumstances. Their single-trip permits will not count towards the annual limit if they haul only the commodity requested on the prior permit and do not exceed the previous weight thresholds of:

  • Up to 120,000 lbs. for metal and
  • Up to 97,000 lbs. for agricultural carriers and those who haul logs, wood chips, tree bark or sawdust under an OSW Agricultural Commodity permit.

Under HEA 1190 and HEA 1150, what constitutes a civil penalty and how much carriers will pay for violating OSW rules will change. More information is in the Oversize/Overweight (OSW) Civil Penalties section of this webpage (scroll down).

Among other OSW-related measures, HEA 1190 also:

  • Instructs INDOT to change permit fees no later than Oct. 1;
  • Allows INDOT to temporarily increase the number of OSW permits for divisible loads issued in response to an emergency or changes in market conditions; and
  • Allows INDOT to suspend overweight divisible load permitting if they observe increases in infrastructure damage on a permitted route or the number of accidents associated with these loads.

Applying for an Oversize/Overweight Permit

Customers can apply for, pay fees and print OSW permit(s) and general provisions online, 24/7. The majority of requests are typically approved on the next business day; however, other factors may extend wait times. Permits will be approved automatically if the applicant selects a predetermined route that fits their load's dimensions.

To reduce the chances of a permit being delayed or rejected, applicants are encouraged to plan or check their route on the INDOT Truckers' Info website before applying for a permit. Taking the extra time to ensure all permit data is entered correctly in the permit application portal also avoids rejects and manual reviews.

Depending on the type of permit and route, you may need to provide additional information when applying for a permit. The following resources may assist in providing accurate route information to MCS for faster processing:

Some customers prefer to use a third-party service to obtain OSW permits. DOR does not endorse or regulate these services. A list of permitting service companies is available for your convenience.

For the Indiana Oversize/Overweight Permitting System to work properly, users should have only one tab open at one time and use the Google Chrome browser. Other tabs may open during the permitting process to show reference information. You will need to close these tabs when you are finished reviewing the information and return to the original tab. More information on how to apply for OSW permits is available in the comprehensive user guide.

Oversize/Overweight (OSW) Civil Penalties

Information below reflects changes in Indiana law as of July 1, 2021.

Under Indiana Code (IC) 9-20-18-14.5(b), a carrier transporting vehicles or loads under a permit and violates Indiana Code 9-20 (including violation of permit guidelines) is subject to a civil penalty of not more than $1,000 for the first violation and not more than $1,500 for each subsequent violation.

Under IC 9-20-18-14.5(c), a carrier that transports vehicles or loads under Indiana Code 9-20 and fails to obtain the required permit(s) is subject to a civil penalty not more than $5,000 for each violation described in an Indiana state police examination report.

Under IC 9-20-18-14.5(d), a carrier that transports vehicles or loads subject to Indiana Code 9-20 and in excess of its legal weight or dimensional limits and for which no permit is available is subject to a civil penalty of not more than ten thousand dollars ($10,000) for each issued Indiana state police examination report.

Civil penalties are:

  • Imposed on the carrier transporting the vehicle or load; and
  • In addition to any fines and/or penalties that may have been separately assessed under Indiana law by law enforcement or a court.

Customers who receive a proposed assessment letter for OSW violations from DOR Motor Carrier Services (MCS) have 60 days from the date of the proposed assessment letter to pay in full, protest the assessment or agree to a settlement amount. Details on how to pay or submit a protest are contained in the proposed assessment letter.

Settlement agreements may be available by contacting the DOR’s Legal Division at OSWsettlement@dor.in.gov. Initiating settlement negotiations with DOR does not remove a customer’s right to protest within 60 days of the date of the proposed assessment letter.

See information on the defenses and mitigating factors DOR may consider in determining whether to eliminate or reduce an assessed civil penalty during settlement negotiations or a protest.

For more information about OSW, refer to the OSW handbook,  MCS Frequently Asked Questions, or call 317-615-7200, Monday through Friday, 8 a.m.–4:30 p.m. ET.
