Missouri oversize load permits
Missouri allows 14'0" unpermitted, which 20 states do. The other 26 cap at 13'6" — so a 14-foot load legal here needs a permit the moment it crosses into most of them.
Missouri permit requirements
The same seven sections for every state, so two states can be compared without re-learning the layout.
Permit required above
Exceed any one of these in Missouri and the load needs a permit. No overall cap on the designated system — the 53' trailer governs. 60' applies more than 10 air miles off it. A trailer measuring more than 53' with the load on it — including any rear overhang — re-activates the state's 60' overall cap. Permigo files it for a flat $20, with the state's own fee billed at cost.
Missouri measures the trailer with the load on it, so a rear overhang counts inside the 53' trailer limit rather than sitting outside it — a 48' trailer with a 6' tail measures 54' and needs a permit. Missouri publishes no separate overhang cap, and marking rules still apply.

Missouri oversize permits, answered
Do I need an oversize permit in Missouri?
You need a permit in Missouri once the load exceeds any one of these: 8'6" wide, 14'0" high, or 80,000 lb gross. There is no overall length cap on a normal tractor-semitrailer — the trailer itself is capped at 53' instead. Axle limits apply too — 20,000 lb on a single axle and 34,000 lb on a tandem.
When does Missouri require an escort?
Missouri requires no escort below 12'6" wide. Above that the requirement depends on the road type as well as the dimension, which is why the same load can need a front escort on a two-lane and a rear escort on a multilane.
Can I move an oversize load at night in Missouri?
Daylight hours only. There is no general weekend blackout. Holiday movement is restricted.
What counts as a superload in Missouri?
A load over 16' wide, over 16'0" high, over 150' long, over 160,000 lb is handled as a superload in Missouri. Allow about 14 business days for review.
How much does a Missouri oversize permit cost?
Permigo charges a flat $20 service fee per state permit. Missouri's own permit fee is billed at cost on the same invoice, itemised, with nothing added. Call +1 (786) 494-6912 and we will price your exact route.
What happens if I move without a Missouri permit?
Moving above Missouri's limits without a permit is a violation, not a paperwork gap. The load can be stopped at a scale or by a trooper and held until a permit is issued, the fine is set by Missouri and the citing officer, and a pattern of violations follows the carrier's safety record. If you are not sure the load needs one, when you need an oversize permit walks through the triggers.
Which kind of Missouri permit do I need?
Most moves take a single-trip permit: one load, one route, a set number of days. Many states also sell annual or blanket permits for loads that stay within routine dimensions; whether Missouri does, and for which loads, is on the state's own permit page. A superload is permitted separately and reviewed by the state — the thresholds are in the answer above. Permigo files whichever kind the load needs at the same $20 flat fee; what Missouri itself charges is on the cost guide.
Is a Missouri oversize permit the same as a Missouri truck permit?
No. A "truck permit" usually means the paperwork a truck needs to cross Missouri at all — a trip permit, a fuel permit (IFTA) or IRP plates — which the state's motor-carrier office issues. An oversize or overweight permit covers one load that exceeds Missouri's legal size or weight, and that is what Permigo files.
