Q - What is GIER?

A - GIER is an industry-sponsored virtual technology alternative to the intermodal equipment marking options that were mandated in Section 390.21 of the final “roadability” regulations issued under Docket No. FMCSA-2005-23315. GIER ties the unique alpha/numeric equipment identification number to the intermodal equipment provider's U.S. DOT Number to identify the responsible party for the equipment under the federal regulations. 

Q - If I am a Motor Carrier and have my own chassis, do I need to register my equipment in GIER?

A - If your company interchanges its chassis to other trucking companies, then you would be considered an Intermodal Equipment Provider and would need to comply with the marking options under Section 390.21 of the FMCSRs of which registering intermodal equipment in GIER is one of the alternative marking options for compliance with this rule.  

Q - Is there a cost to subscribe to GIER?

A - GIER Subscribers are charged a quarterly fee based on the number of active chassis registered for their company in GIER at the time of the billing.  Click here for GIER Fee Schedule
