How do I change my MCS-150 data, such as Vehicle Miles Traveled (VMT) or Power Units (PUs)?

Although the Federal Motor Carrier Safety Administration (FMCSA) suggests that motor carriers update their MCS-150 every two years, motor carriers should understand that this is just the minimum requirement; motor carriers may update their MCS-150 form at any time. The FMCSA encourages carriers to update their MCS-150 any time there is a change in their data. Since the Safety Measurement System (SMS) uses VMT and PU data, motor carriers may consider updating their form every year. Motor carriers can update their MCS-150 data online at the FMCSA website.

The SMS updates monthly. MCS-150 changes will not appear immediately in the SMS, but likely will show up the following month. However, MCS-150 updates should show up more quickly on the SAFER website at www.safer.fmcsa.dot.gov.
