International Registration Plan

Full Reciprocity

Upcoming simplification to IRP!

Beginning in 2015, cab-cards will show all jurisdictions! No more "add state or province". No more "over 100 percent fees" for added jurisdictions. If you have IRP, no more trip permits. This is true IRP-wide. All states and provinces will be implementing this. This has been referred to as Full Reciprocity or the Full Reciprocity Plan, and was adopted by IRP by ballot in October 2013.

How it Will Work

The effective date for your fleet depends on your fleet’s IRP expiration date.

The New Rules Apply for Registration Periods Beginning Jan. 1, 2015 or Later

For example, registrations expiring December 2014 (or later) that are renewing for operation in 2015, your cab-card will show all IRP states and Canadian provinces. You’ll no longer need to select jurisdictions in which you intend to operate. Your IRP fees will be calculated based on your June-July "reporting period" distances. If you are a new carrier without a reporting period history, you’ll pay fees based on the South Carolina Average Per Vehicle Distance Chart.

You’ll be able to operate in any IRP jurisdiction without the trouble and expense of adding a jurisdiction, nor of buying a trip permit. For each IRP renewal, fees will be charged based on the fleet’s "reporting period" distance.

For renewals of registrations expiring November 2014 or earlier – thus with a new expiration date November 2015 or earlier – the old rules will continue to apply through the expiration date in 2015. Cab-cards will only display those jurisdictions specifically requested by the carrier.

IRP General Information

The purpose of the International Registration Plan (IRP) is to promote and encourage the fullest possible use of the highway system by authorizing the proportional registration of fleets of vehicles and the recognition of vehicles proportionally registered in other jurisdictions, thus contributing to the economic and social development and growth of all jurisdictions.


In accordance with the plan, an interstate carrier is only required to submit an application with the jurisdiction in which he is based. The base jurisdiction in turn issues the apportioned license plate and cab card. Inasmuch as the cab card will list all jurisdictions in which the registrant has paid registration fees, it is the only vehicle registration required to operate interstate or intrastate in IRP jurisdictions. However, all other requirements pertaining to fuel or any other tax must be in compliance prior to entry into each state.


Apportioned vehicles are defined as any vehicle used or maintained primarily for the transportation of property and:


  1. Is a power unit having 2 axles and a gross vehicle weight or registered gross vehicle weight in excess of 26,000 pounds or 11,793.401 kilograms; or
  2. Is a power unit having three or more axles regardless of weight; or
  3. Is used in combination, when the weight of such combination exceeds 26,000 pounds or 11,793.401 kilograms.

Vehicles, or combinations thereof, having a gross vehicle weight or registered gross vehicle weight of 26,000 pounds or less and two-axle vehicles may be proportionally registered at the option of the registrant.

Insurance Requirements for Apportioned Vehicles

Each South Carolina based registrant must maintain liability insurance coverage on all vehicles bearing a South Carolina apportioned license plate. The insurance certification on the front side of the Schedule A/E or C must be completed with the insurance company name, policy number, policy dates and the agency/agent’s name.

Heavy Vehicle Use Tax

In accordance with the Surface Transportation Assistance Act of 1982, carriers must submit to the Department of Motor Vehicles proof of payment of Federal Heavy Vehicle Use Tax on certain licensed vehicles.


The owner of any vehicle with a declared gross vehicle weight of 55,000 pounds or more, regardless of the type of vehicle, must furnish this proof of payment.


Taxable gross weight of a highway motor vehicle is determined with reference to the sum of: (1) the actual unloaded weight of such highway motor vehicles (fully equipped for service); (2) the actual unloaded weight of any trailers or semi-trailers (fully equipped for service) customarily used in combination with such highway motor vehicles; and (3) the weight of the maximum load customarily used in combination with such highway motor vehicles.


Heavy Vehicle Use Tax returns should be filed with the Internal Revenue Service from July 1 to August 31 of each year for any vehicle currently licensed.


Customers who register 25 or more vehicles for any taxable period are required to electronically file their 2290 tax return with the IRS.  If a customer acquires additional vehicles after the initial filing of the tax return, there is no requirement for the customer to electronically file a 2290 tax return for those additional vehicles.  SCDMV will no longer accept tax returns if the customer is registering 25 or more vehicles.


Registrants must furnish an IRS Form 2290, Schedule 1, validated by the IRS for the current tax year or a copy of this form accompanied by a photocopy of the canceled check (front and back) submitted for payment of the tax.


A vehicle may be registered without proof of payment of this tax, providing the applicant presents a manufacturer’s certificate of origin or title indicating that the vehicle was purchased within sixty (60) days of the date of application for registration. HVUT must be paid within 30 days of registration with the Department to avoid penalties by the IRS.

Vehicles Exempt from HVUT

Regardless of the purchase date, some vehicles are exempt from the requirement to pay HVUT because of the mileage on the vehicle, because the vehicle is registered to a governement entity or a specific organization, or because of the type of vehicle.

1.       Mileage exemption - Vehicles driven 5,000 miles a year or less (7,500 miles a year or less for agricultural vehicles).


If a vehicle is exempt because the vehicle is driven a limited number of miles, the customer must present an original Form 2290 (Schedule 1, Part 2) stamped by the IRS for the current tax year which lists the exempt vehicles.  Photocopies will not be accepted for exempt vehicles.

2.       Government entities or organizations –  These vehicles are not required  to be listed on the 2290 Schedule I. However,  a  Form MC2290 – Heavy Vehicle Use Tax  Exemption must be completed.


The following government entities or organizations are not required to pay a HVUT; therefore, a Form 2290 will not be required for those vehicles and the vehicles may be registered or renewed following the normal process.

a)       The federal government

b)       The District of Columbia

c)       A state or local government

d)       The American Red Cross

e)       A nonprofit volunteer fire department, ambulance association or rescue squad

f)         A Native American tribal government only if use of the vehicle involves the exercise of an essential tribal government function

g)       A mass transportation authority if it is created under a statute that gives it certain powers normally exercised by the state


Customers can get immediate help with their Form 2290 questions by calling the IRS Help Line at 1-866-699-4096 (toll free). The hours of operation are Monday through Friday, 8 a.m. to 6 p.m. EST, or by visiting their Web site,  

3.       Specially designed mobile machinery for nontransportation functions - A self-propelled vehicle is not a highway vehicle if all the following apply.  These vehicles are not required  to be listed on the 2290 Schedule I. However,  a  Form MC2290 – Heavy Vehicle Use Tax Exemption must be completed.

a)       The chassis has permanently mounted to it machinery or equipment used to perform certain operations (construction, manufacturing, drilling, mining, timbering, processing, farming or similar operations) if the operation of the machinery or equipment is unrelated to transportation on or off the public highways,

b)       The chassis has been specially designed to serve only as a mobile carriage and mount (and power source, if applicable) for the machinery or equipment, regardless of whether the machinery or equipment is in operation, and

c)       The chassis could not, because of its special design and without substantial structural modification, be used as part of a vehicle designed to carry any other load.

4.       Vehicles specially designed for off-highway transportation -   These vehicles are not required  to be listed on the 2290 Schedule I. However,  a  Form MC2290 – Heavy Vehicle Use Tax Exemption must be completed.


A vehicle is not treated as a highway vehicle if the vehicle is specially designed for the primary function of transporting a particular type of load other than over the public highway and because of this special design, the vehicle's capability to transport a load over a public highway is substantially limited or impaired.


To make this determination, you can take into account the vehicle's size, whether the vehicle is subject to licensing, safety or other requirements, and whether the vehicle can transport a load at a sustained speed of at least 25 miles per hour. It does not matter that the vehicle can carry heavier loads off highway than it is allowed to carry over the highway.


5.       Nontransportation trailers and semi-trailers -   These vehicles are not required  to be listed on the 2290 Schedule I. However, a  Form MC2290 – Heavy Vehicle Use Tax Exemption must be completed.


A trailer or semi-trailer will not be treated as a highway vehicle if it is specially designed to function as an enclosed stationary shelter for carrying on a nontransportation function at an off-highway site. For example, a trailer that is capable of functioning only as an office for an off-highway construction operation is not a highway vehicl

Replacement Cab Card

Requests for duplicate or replacement cab cards should be submitted on Form 3090. The fee will be $1.00 per card. There is no charge for corrections due to departmental error or address changes.

Back to Top

Replacement License Plate

To replace a lost, stolen or mutilated license plate, the registrant must complete Form 452-A. The fee will be $6.00 per replacement license plate. Be sure to submit these forms and fee, along with your original cab card for the license being replaced, directly to the Motor Carrier Services Office, whether by mail or in person, unless temporary authorization has been issued. In which case, these forms and fee must be submitted to the Branch Office personnel issuing the temporary authorization. The Branch Office will then forward these documents to the Motor Carrier Services Office. You should receive replacement license plates, and duplicate cab cards within two (2) weeks. If not, please contact Motor Carrier Services.


Back to Top


Credentials for the registration year should be on the vehicle no later than mid-night of the last day of your expiration month. License plates must be mounted on the front of the power unit and the back of trailers and semi-trailers. The original cab card must be available for inspection by appropriate enforcement personnel; copies are not acceptable.

Back to Top

Adding or Deleting Vehicles

When adding or deleting a vehicle to or from a fleet, it will be necessary to file a supplemental application (Schedule C) in the same manner as the original. If a Temporary Authority (TA) is applied for, a completed Schedule C must be surrendered at the time that the registrant picks up their TA at the DMV Branch Office.


South Carolina registration fees may be transferred from the deleted vehicle to the added vehicle, providing it is a vehicle of the same type and registered in the same name. A transfer fee of $10.00 will be due to this state, plus any fees, which may be due to other jurisdictions. Not every IRP member jurisdiction allows for the transfer of registration fees, therefore, you will be charged a prorated registration fee for those states.


In those cases where a deleted vehicle is not being replaced, the registrant is required to submit a completed Schedule C to Motor Carrier Services within 30 days. The IRP cab card and license plate must also be returned to this Department, where it will remain on file until expiration. Should a replacement vehicle be purchased prior to expiration of the apportioned license and you wish to transfer the registration fees, you should contact Motor Carrier Services for assistance.

Adding Jurisdictions

Providing original applications IRP Schedule A/E and Schedule B has been filed for a current year, the registrant may expand his operation into and through a jurisdiction not previously included by filing a supplemental application (Schedule C) showing the additional member jurisdiction, desired registration weight, and estimated mileage. Be sure to explain why the mileage is being estimated by completing a new Schedule B showing the mileage for the added jurisdiction only, if not using the provided estimated chart.

Back to Top

Weight Increase

Should the registrant decide to increase his registered weight for any member jurisdiction, a Schedule C must be filed with this Department. Additional fees will be calculated for the increase in weight for the remaining portion of the registration year.


NOTE: Vehicle weights will not be decreased during the license year.

Weight decreases can only be made at license renewal time.
