Electronic Logging Device:

The congressionally mandated electronic logging device (ELD) rule makes tracking, managing and sharing driving records with law enforcement more straightforward and faster. Howerver, most ELDs fall short when it comes to paying and documenting fuel taxes and IRP. See DOR's guidance on ELDs and audit tips to help ensure you keep accurate records.

Businesses with commercial vehicles can easily renew plates with our streamlined process.

Businesses operating motor vehicles over 26,001 pounds in the state of Indiana must file a fuel tax return.

Bulk Milk Transports 

In June 2020, INDOT waived holiday travel restrictions for permitted overweight bulk milk transports weighing up to 154,000 lbs. GVW only. This includes vehicles permitted with single-trip overweight permits and those with annual bulk milk permits. For more information, call Motor Carrier Services at (317) 615-7320 or email IndianaOSW@dor.in.gov.

OSW Emergency Relief Permits

On July 30, Governor Eric Holcomb renewed his declaration of a state public health emergency. The process to obtain oversize/overweight permits for vehicles hauling goods and supplies intended for emergency response/relief from conditions caused by COVID-19 has changed.

To apply for these permits, carriers must now contact INDOT Freight Manager Leslie Morgan by email. Upon approval, INDOT will issue a carrier-specific emergency permit that can be used in conjunction with these loads.

These permits are intended only for loads of materials and supplies that are being hauled for emergency response or relief due to conditions caused by COVID-19. Loads cannot travel over legal weight limits when the materials or supplies hauled can no longer reasonably be considered part of the emergency response or relief efforts, even if the emergency permit is still valid.

DOR’s Oversize/Overweight Permit Section will continue to handle applications for other OS/OW permit types.

IRP System Upgrade Information

A new IRP system update went live on June 14. One of the major changes involves new Excel templates and requirements for uploading files for qualified accounts. Please review all of the information on the MCS system for more details, including a video, training materials and new templates.

All upload templates changed as of June 14, 2020, so be sure to begin using the new templates.
