IFTA, IRP and Form 2290 do three different jobs
These three get mixed up constantly, because all of them involve heavy vehicles, government paperwork and deadlines. They are run by different authorities and answer different questions.
Form 2290 is a federal tax paid to the IRS. IFTA is a fuel-use tax agreement settled quarterly with your base jurisdiction. IRP is apportioned registration across states. The clearest side-by-side is IFTA vs IRP vs Form 2290.
One plate, many jurisdictions
Apportioned plates let a commercial vehicle run across many states and provinces on a single registration, with the fees divided in proportion to the miles travelled in each. They are issued under the International Registration Plan.
You generally need them for a qualifying vehicle operating in two or more jurisdictions — broadly, over 26,000 lbs or with three or more axles. How to get apportioned plates and tags walks through the application.
No Schedule 1, no plate
This is where the HVUT stops being an abstract tax. States will not renew registration on a heavy vehicle without proof the tax has been paid, and IRP renewals ask for the same document.
One truck missing its Schedule 1 is one truck parked in the yard instead of earning. Schedule 1 for vehicle registration explains what the DMV is actually checking.
The USDOT number comes before almost everything
A USDOT number is issued by the Federal Motor Carrier Safety Administration and follows a carrier's safety record through inspections, audits and compliance reviews. For most operators it is the first registration needed before running legally.
The thresholds are lower than many expect — a gross vehicle weight rating of 10,001 lbs or more in interstate commerce is enough, as is carrying placardable hazardous materials. USDOT number registration requirements lists them.
PRISM ties your safety record to your registration
Performance and Registration Information Systems Management is the programme that connects a carrier's safety standing to its ability to register vehicles. In PRISM states, your USDOT number and safety status are checked at the registration counter.
The consequence is direct: a carrier under a federal out-of-service order can be refused registration until the order is resolved. Safety and paperwork are not separate problems. Understanding PRISM.
The MCS-150 update nobody remembers
Every motor carrier must refresh its MCS-150 with the FMCSA every two years — even when absolutely nothing has changed. Miss it and the USDOT number can be deactivated, which cascades into registration problems.
The deadline is hidden inside your own USDOT number: the last digit sets the filing month, the next-to-last decides odd or even year. The MCS-150 biennial update due date checker works it out for you.
CDL classes in one paragraph
Class A covers combination vehicles over 26,000 lbs where the towed unit is over 10,000 lbs. Class B is a single vehicle over 26,000 lbs. Class C covers vehicles built for 16 or more passengers, or hazmat loads that do not meet the Class A or B weights.
Endorsements sit on top of the class — H for hazardous materials, and others for tankers, doubles and passengers. The full breakdown is in the complete CDL guide.
