How often must International Registration Plan (IRP) registrations be renewed?

The correct answer is that International Registration Plan (IRP) registrations must be renewed annually, with mileage reporting for the prior year. This requirement is in place to ensure that the fees for the registration are based on the amount of travel or mileage attributed to each jurisdiction within the IRP.

Each year, IRP registrants are required to report the total distance traveled in each participating jurisdiction in the previous registration year. This mileage reporting is crucial because the fees associated with registering under the IRP are proportional to the distance traveled in each state, ensuring a fair allocation of registration costs based on usage.

In addition to the annual renewal and mileage reporting, this process helps maintain compliance with regulations, as it allows the jurisdictions to collect fees efficiently and equitably. This structure helps support road maintenance and infrastructure in the respective states based on the wear and tear caused by commercial vehicles.

The other choices regarding different renewal timelines do not align with the established regulations of the IRP, as there is a specific annual requirement that includes the reporting of mileage to reflect the actual use of roads across jurisdictions.
