The FMCSA requires all interstate carriers to file a MCS-150 or MCS-150B, if a Safety permit is required, every 24 months based on the last two digits of the US DOT number.  The last digit of the number dictates the month and the second to last digit dictates the year.  If the second to last digit is even you report in even number years, an odd digit, you report in odd number years.  Now if there has been a change to your operation, increase in units, change of address, etc. you can file at any time and is recommended.  You can file your MCS-150 online, fax or mail.  A motor carrier that submits similar information to a State as part of its annual vehicle registration requirement under the Performance and Registration Information System (PRISM) complies if it files this information with the appropriate State commercial motor vehicle (CMV) registration office.  The Motor Carrier Identification Report, Form MCS-150, and the Combined Motor Carrier Identification Report and HM Permit Application, Form MCS-150B, with complete instructions, are available from the FMCSA website: (Keyword "MCS-150" or "MCS-150B"); from all FMCSA Service Centers and Division offices nationwide; or by calling 1-800-832-5660.   The report can be updated online at or by faxing the form to the FMCSA at 703-280-4003.

Frost Laws in 16 states and 9 Provinces

Spring weather often creates driving challenges. Specifically, the change in ground temperature can damage roads and vehicles and result in "roller coaster" rides from "wavy roads."

Consequently, motor carriers need to monitor the many state and provincial spring weight restrictions or risk damage to the road and/or the rig.

Be Ready for an Alternate Route

To preserve the integrity of the roadways, many states impose seasonal weight restrictions as early as late February and some lasting into May.

As drivers travel through regions that are experiencing spring thaws, they need to watch for posted signs indicating allowable weights. Signs may also indicate a reduced speed limit.

Trip planning may involve visiting some state websites to know if a specific highway is accessible to your vehicles. In addition, if a driver comes upon a weight restriction, he or she will need to find an alternative route, possibly contacting dispatch for assistance.

To ignore postings may result in more than just fines. It may result in damage to the roads, your vehicle, and/or cargo, and could result in an accident if the roadway is difficult to maneuver.  Click here to view the laws in states and provinces.
