Who must register under the International Registration Plan (IRP)?

• A. All passenger vehicles traveling interstate
• B. Commercial vehicles over 26,000 lbs GVW or with three or more axles traveling in two or more jurisdictions
• C. Only vehicles that are registered in multiple states
• D. Private vehicles used for commercial purposes

Answer: (B)

The International Registration Plan (IRP) is designed to simplify the registration process for commercial vehicles that operate in multiple jurisdictions. Specifically, vehicles that are over 26,000 pounds Gross Vehicle Weight (GVW) or that have three or more axles require registration under the IRP when they travel in two or more states or provinces. This plan ensures that fees are distributed fairly among the states and provinces where the vehicle operates.

By registering under the IRP, these commercial vehicles can avoid the complexities of having to register separately in each state they operate in, making it more efficient for fleet operators and drivers. The requirement applies specifically to larger commercial vehicles, aligning with their operational needs while exempting smaller passenger vehicles and certain other types of vehicles that may not frequently cross state lines or do not meet the weight requirements.
