The Federal Motor Carrier Safety Administration has finalized rules requiring all interstate motor carriers to file a new form MCS-150 every 24 months.

The rule satisfies a requirement of the 1999 Motor Carrier Safety Improvement Act and was published as an interim final rule in November 2000.
The updated forms will be due on a staggered schedule according to the USDOT number. If a motor carrier’s number ends in 1, it must file the MCS-150 update by the end of January and every second January thereafter. If the number ends in 2, 3, 4, 5, 6, 7, 8 or 9, the carrier must file by the end of February, March, April, May, June, July, August or September, respectively. If the number ends in zero, the update must be filed by the end of October.
If the next to last digit in the motor carrier’s USDOT number is odd, the carrier must file its MCS-150 update in odd-numbered years. If the next to last digit is an even number, the carrier must file in even years. FMCSA noted that some new carriers may have to submit their first update less than two years after the initial filing, but all motor carriers should be on a two-year rotation after this first round of updates.
There are two situations where a motor carrier may have to file updated information more frequently than every two years: 1) verification of information during the course of compliance reviews; and 2) registration in states that are participating in the PRISM program where MCS-150 data is updated annually.
The form can be filed electronically or mailed. Detailed instructions are available at the FMCSA website, www.fmcsa.dot.gov.
