Tennessee: permisos de carga sobredimensionada
Límites legales de tamaño/peso, umbrales de escolta, restricciones de circulación y contacto de la oficina de permisos para Tennessee.
Estas cifras son un resumen de referencia de las reglas estatales publicadas públicamente, no un sustituto de un permiso emitido por el estado ni asesoría legal.

Tennessee sets NO maximum semitrailer length and NO overall combination length for a truck tractor + semitrailer. What it regulates instead is a 50 ft KINGPIN-TO-REAR-OF-LOAD distance — see the kingpin figures. ⚠️ TDOT's own FAQ headlines this as "Length: 50 feet for truck tractor + semi-trailer combination", which reads as a 50 ft COMBINATION limit and is absurd on its face (a tractor alone is about 20 ft). Publishing 50 ft as a trailer or combination length is wrong in BOTH directions: it flags legal 53 ft vans as oversize, AND it gives no warning at all to a legal-length trailer with a forward kingpin setting, which IS illegal here. ROAD CLASS: the tractor-semitrailer allowance is granted "over the federal and state highway system" while the 65 ft straight-truck-with-trailer limit applies "on any highway". ⚠️ KNOWN DISCREPANCY, resolved conservatively: commercial publishers render TCA 55-7-201(c) with 52 ft, but EVERY official Tennessee source reachable (TN Secretary of State compiled TDOT rule eff. 15 May 2018, the tn.gov 2017 rules PDF, and both current TDOT permit FAQs) says 50 ft, with 52 ft only as a livestock/automobile exception. We publish the official 50 ft — the lower, safer figure — and record the conflict here rather than adopting an unverifiable number.
⚠️ TENNESSEE MEASURES TO THE REAR OF THE LOAD, NOT THE REAR AXLE. TDOT rule 1680-07-01-.01: "the over length kingpin is measured from the kingpin to the rear of the trailer or overhang. If the kingpin is over 50 ft the vehicle or load is over length" and needs a permit. This 50 ft is NOT comparable to the 41-43 ft kingpin-to-rear-AXLE figures in other states. Over 48 ft from the point of attachment additionally requires kingpin-to-rear-axle of 41 ft or less. Exceptions: 52 ft for livestock/automobiles; 75 ft total for poles, logs or timber in single lengths.
Umbrales de escolta / vehículo piloto (consulta el glosario para los términos, los requisitos de certificación para el conductor)
Estas cifras de escolta dependen de la ruta: pueden cambiar según la clasificación de la vía, el ancho del carril, si la carretera es de dos o de varios carriles, y la hora del día. Confirme con la oficina de permisos antes de despachar.
- Escolta delantera requerida por encima de
- 12.5ft de ancho
- Escolta trasera requerida por encima de
- 12.5ft de ancho
- Ambas escoltas requeridas por encima de
- 13.5ft de ancho
- Escolta de altura requerida por encima de
- 15ft de alto
Per TDOT Rule 1680-07-01-.06/.10/.11/.12: Width 8'6"-10' = no escort. Width >10'-12'6" = escort only where 2-lane pavement <24' wide (1 escort precedes). Width >12'6"-13'6" = 1 escort (precede on 2-lane, follow on interstate/4-lane). Width >13'6"-16' = front + rear escorts on all highways. Width >16' = front + rear + route survey (superload). Height 13'6"-15'6" needs permit; height >=15' = front escort with vertical height indicator. Length >90'-120' = 1 rear escort; >120' = front + rear. Flagperson required at bridge structures where roadway width <20'. Law-enforcement escort at TDOT discretion for super-heavy/extra-overdimensional loads.
Restricciones de circulación
- Circulación nocturna
- Generalmente permitida
- Circulación en fin de semana
- Generalmente permitida
- Circulación en domingo
- Generalmente permitida
OFFICIAL DEFAULT: continuous movement 24 hours/day, 7 days/week (Rule 1680-07-01-.04). Exception: loads exceeding 12'6" wide, 15' high, or 90' long may NOT move on the interstate 7-9 a.m. and 4-6 p.m. Mon-Fri in counties with population over 250,000. Holiday heavy-traffic restrictions may apply. Super-heavy/extra-overdimensional loads may receive additional time restrictions. Permits subject to inclement-weather restrictions. NOTE: many broker sites claim TN is 'daylight only, no Sunday' - that is SUPERSEDED by the 2018 rule; continuous movement is the official default.
Bloqueos por festivos: Heavy-traffic restrictions may apply: Easter (after 6 p.m. Thu before Good Friday through Easter Sunday); Memorial Day (after noon preceding Friday through Memorial Day); Independence Day (July 3-4, plus adjacent weekend days if applicable); Labor Day (after noon preceding Friday through Labor Day); Thanksgiving (after noon Wed before through Sunday after); Christmas/New Year's (Dec 24 through Jan 1, with weekend extensions).
Umbrales de supercarga
- Ancho superior a
- 16ft
- Altura superior a
- 15.6ft
- Longitud superior a
- 150ft
- Peso superior a
- 165,000 lbs
TDOT 'super heavy' = gross weight exceeding 165,000 lbs. 'Extra-overdimensional' = width exceeding 16' OR height exceeding 15'6". These require a route survey, traffic-control plan, and possible law-enforcement escort (Rule 1680-07-01-.12). Length is not part of TN's super-heavy/extra-overdimensional definition.
Costo estimado del permiso Verifica antes de confiar
