An IRP compliance audit is the examination of a registrant's operational distance records, including source documents, to verify both the registration distances reported on the renewal application and the accuracy and function of the registrant’s distance accounting system for its fleet.
IRP base jurisdictions must examine an average of 3% of renewed fleets each year to ensure compliance with the IRP and to confirm that the proper revenues are collected for each member jurisdiction.
As a result, every motor carrier registered with Texas as its base jurisdiction for apportioned registration will be subject to an audit of its operational distance records at some point. Registrants are selected both randomly and through information received from other sources.
Methodology
If selected for an IRP compliance audit, the registrant must submit:
- A completed Audit Questionnaire
- A signed audit engagement letter
- Operational distance records (such as monthly or quarterly vehicle distance summaries, annual fleet distance summaries, and source documents)
Additional records may be requested by the compliance auditor during the audit process.
The Texas Department of Motor Vehicles uses non-statistical sampling when conducting compliance audits. Vehicles are randomly selected from the registrant's fleet. Source documents, such as Individual Vehicle Distance Records (IVDRs), must be provided for no fewer than three representative months within the distance reporting period.
Distance is traced from the IVDRs to the summaries.
Records must be legible, separated by unit number, and in date sequence. Records may be submitted:
- By email: TxDMV_IRPaudit@TxDMV.gov
- By mail (via tracking number) on a USB portable storage device (flash drive) to:
