How this service works
LEGAL / PERMITS_REQUIRED / SUPERLOAD_REVIEW verdict for an oversize/overweight truck load across every state on the US route. Per-state permit trigger, escort/pilot matrix, curfews, fee estimate (always verify-with-state), superload flag, source_url. Feet+inches or decimal input. State-level only. Fail-closed.
Output
A per-state breakdown including: a verdict of LEGAL, PERMITS_REQUIRED, or SUPERLOAD_REVIEW; which dimension or weight threshold triggered the permit requirement; escort/pilot car matrix (lead, rear, or both); curfew time windows; an estimated permit fee (with disclaimer to verify with the state); a boolean superload flag; and a source URL for the official state regulations referenced.
Example use cases
Multi-state heavy haul compliance check
“We're moving a 200,000 lb transformer on a route through Georgia, Tennessee, and Kentucky — check each state for permit requirements, whether we need pilot cars, any travel curfews, and flag if we hit superload thresholds anywhere.”
Wide load route clearance for construction equipment
“I need to transport an excavator that's 16 feet wide and 13 feet 8 inches tall from Ohio through Indiana to Illinois — tell me which states require permits, what escort vehicle rules apply, and estimate the permit fees.”
Pre-trip legal status check for oversize flatbed
“Before we dispatch this flatbed carrying a 90-foot-long load at 105,000 lbs through Nevada and Utah, can you tell me if it's legal as-is or if permits are required, and what curfew windows we'd need to work around?”
Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/oversize-requirements-checkWhen to prefer
Use this endpoint when you need a fast, multi-state permit status assessment for a specific oversize or overweight truck load before dispatching or route planning. It is particularly valuable when a load crosses multiple state lines and you need a consolidated, per-state verdict with escort, curfew, and superload details in one call. It is not a substitute for official state permit applications and fee estimates should always be verified with the relevant state DOT.
Side effects
- Missing or malformed load dimensions or weight causes validation failure
- Route states not recognized or misspelled returns an error
- Unsupported measurement format (neither feet+inches nor decimal) causes parsing failure
- Regulatory data may be stale — fee estimates and thresholds require independent state verification
- Network or upstream data source unavailability returns a service error
- Payment of 0.5 USDC via x402 not completed results in 402 Payment Required response
