Rhode Island commercial vehicle weight limits follow the federal Interstate standard of 80,000 lbs gross, 22,400 lbs per single axle, and 36,000 lbs per tandem axle group. The federal bridge formula (23 U.S.C. 127) applies on all routes. Rhode Island imposes spring weight restrictions on state routes typically March through April. Check RIDOT for current restricted routes and active postings before routing heavy loads during this period. Oversize and overweight permits are available from RI DOT for loads exceeding standard limits. Verify current road-specific postings with the Rhode Island DOT before routing heavy loads.

Yes. Rhode Island imposes spring weight restrictions on state routes typically from March through April. These restrictions protect road infrastructure during the freeze-thaw cycle. Interstate highways are generally not subject to spring restrictions, but state routes and secondary roads are. Check the RIDOT website at ridot.net for current restricted routes before dispatching heavy loads in spring.
Rhode Island has historically allowed higher single axle (22,400 lbs) and tandem axle (36,000 lbs) limits on state routes under a grandfather provision. These higher limits facilitate port operations and regional distribution traffic. Federal Interstate limits of 20,000 lbs single and 34,000 lbs tandem still apply on Interstate highways.
Rhode Island oversize/overweight permits are issued by the Rhode Island DOT. Apply at ridot.net. Single-trip permits are available for most oversize or overweight loads. Annual permits are available for qualifying recurring heavy operations. Superloads and extremely wide or heavy moves require route engineering review and may require police escort.
Yes — this is critical in Rhode Island. Many older bridges throughout Providence and across the state have individually posted weight limits that are significantly lower than state or federal maximums. Always check your planned route against RIDOT bridge weight postings and observe all posted signs. Overweight violations on posted bridges carry substantial fines.
