Legal size & loaded measurements
General width
8′6″Ordinary vehicle-and-load limit; safety-device, vehicle and load exceptions may apply.
Loaded height
13′6″Ordinary vehicle-and-load limit; listed exceptions and actual route clearances apply.
Loaded dimensions
Tennessee baselines are 8 feet 6 inches width, 13 feet 6 inches height, 80,000 pounds gross, 20,000 single axle and 34,000 tandem; length depends on configuration and commodity.
Axles, weight & bridges
Use trailer width, axle/group weights and spacing, gross weight, registration, bridge postings and Structures review; GVW alone cannot authorize a Tennessee move.
Permits, routes & larger loads
Roads & authorities
TDOT permits govern the state highway system; coordinate local governments for off-system roads and obey bridge, construction and route-owner controls.
When a permit is needed
Use the applicable TDOT single-trip or annual product for nondivisible OS/OW moves; ordinary single-trip permits are ten calendar days and scoped programs may differ.
Larger-load review
Permit axle bands vary by trailer width. Over 165,000 pounds, over 16 feet width or over 15 feet 6 inches height requires specialist route/engineering review; issued conditions control.
State permit fees
Single-trip agency fee example
$20 for this Tennessee planning example: a nondivisible load measuring 8′7″ wide, 13′ high and 70′ overall, at 72,000 lb gross on a five-axle rig with a 48′ trailer. The example uses 100 in-state miles. Change the load details in the calculator for your move.
What the agency estimate includes
The calculator applies Tennessee's maintained single-trip permit schedule to the loaded vehicle and the supplied fee inputs. It itemizes the supported state charges, including weight or distance charges where applicable. Annual permits, special products, local permissions and payment-method charges need their own applicable schedule.

About the example equipment
The samples use ODPermit’s editable 48 ft flatbed · 5 axles planning profile. Loaded dimensions, gross weight, 100 state miles and Texas registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.
Great Dane Freedom trailer specifications — 48 ft platform; the illustrated 40 in drop deck and 20 in drop support a 60 in upper-deck planning height. Combined tare and tractor geometry are editable ODPermit assumptions.
Pilot cars, height poles & surveys
14′6″-wide load example
Example: 14′6″ wide × 13′ high, 75′ overall, 72,000 lb gross, zero overhang or rear projection, ordinary nondivisible freight in daylight. Depending on the road or permit conditions: A flagperson is required at bridge structures with less than 20 ft of roadway width for this overwidth movement. All road types: 1 front and 1 rear pilot cars.
17′6″-high load example
Example: 9′ wide × 17′6″ high, 75′ overall, 72,000 lb gross, zero overhang or rear projection, ordinary nondivisible freight in daylight. Plan a route survey above 16 ft wide or at 15 ft high and above. Rule 1680-07-01-.10 requires a survey identifying overpass clearances from 15 ft high; the moving height-pole escort starts above 15 ft. All road types: 1 front (height pole required) pilot car.
Travel hours & road restrictions
Travel hours
Tennessee defaults to continuous 24/7 movement, but county rush-hour, escort, holiday, superload, house and weather restrictions can narrow the window.
Current route restrictions
Check the 2026 holiday bulletin, county curfews, TDOT route/bridge maps, construction notices, SmartWay conditions and weather before departure.
Signs, flags & safety equipment
Safety equipment
Use TDOT-required banners, solid red flags, projecting-load lamps, escort signs/lights/radio, insurance and cargo-securement controls exactly as the current permit requires.
What the driver needs
Carry the permit
Carry the original or authentic scannable electronic/paper permit, follow the listed route and present it to enforcement when requested.
Prepare the driver packet
The packet must match the permitted vehicle/load, route, date, dimensions, axle diagram, TNTRIPS permit, escort instructions, insurance and any bridge/Structures or local-road attachments.
Special equipment & permit programs
Special permit programs
Seed-cotton, sealed containers, fixed-load vehicles, site-built houses, mobile homes, houseboats, emergency towing and relief loads have distinct scoped rules.
BEFORE THE TRUCK ROLLS
Turn the estimate
into a permitted move.
Confirm the loaded measurements, carrier details, travel dates and exact pickup and delivery. We can help coordinate permits, escorts and route surveys around those facts.
