Overall length: No NN cap*
*For a tractor with one compliant semitrailer on the National Network. Other combinations, trailers, projecting loads and local access have separate limits; see the state measurements below.
Interstate weight: 80,000 lb*
*Federal baseline, subject to the bridge formula, registration and postings: 20,000 lb single axle and 34,000 lb tandem. A particular configuration may have a lower limit; state grandfather allowances need verified spacing and route eligibility.
Legal size
Legal limits are 8′6″ wide and 13′6″ high. Length and weight depend on the vehicle setup.
Weight limits
Gross weight alone does not settle it in Connecticut. Use every axle, spacing, wheelbase, tire, setup, registration and route detail.

1CTDOT — Oversize/Overweight Frequently Asked Questions · checked Oct 13, 2026What official sources leave open13
Where Connecticut’s official sources disagree or say nothing, confirm with the agency before dispatch.
- 2027 holiday restrictions are not yet published; only the 2026 list is available.
- Legal axle conflict: the CTDOT FAQ lists 24,400 lb for axles spaced 6′ or more apart, but C.G.S. § 14-267a sets 22,400 lb per single axle. The statute value is used here.
- Manufactured housing width conflict: Regulation § 14-270-25 (1985) caps house trailers at 14′ wide and limits units over 12′ wide to 9 a.m.–4 p.m. Tuesday–Thursday; the newer 2020 CTDOT guidelines and C.G.S. § 14-262b allow up to 16′ wide (night moves over 14′) and set rush-hour limits instead. The newer guidelines are used here.
- Maximum width conflict: Regulation § 14-270-24 limits width to 16′ except house and national-defense moves, while the FAQ treats loads over 16′ wide as superloads, implying wider moves can be permitted.
- Escort at exactly 13′6″ wide: C.G.S. § 14-270(b) calls for a single front escort up to and including 13′6″ on undivided highways, while the FAQ table requires front and rear escorts at 13′6″ or greater.
- Travel hours: the regulation limits moves to daylight (half hour after sunrise to half hour before sunset), while the FAQ says superloads move at night only; CTDOT sets superload hours on the permit.
- Connecticut publishes no pilot car driver certification or reciprocity requirement in the sources checked.
- No published lead time for ordinary single-trip permits; superloads need at least five business days.
- Weekend travel conflict: Regulation § 14-270-18(a) (1985) says permits are not issued for Saturday, Sunday or holiday moves, while CTDOT's current single-trip page offers weekend permits on request (Saturday and Sunday, daylight to noon) for loads up to 12′ wide, 13′6″ high, 80′ long and 160,000 lb.
- Pilot car sign conflict: Regulation § 14-270-21(e)(3) calls for a top-mounted 'OVERSIZE LOAD AHEAD/FOLLOWING' (or WIDE/LONG LOAD) sign, while the CTDOT FAQ calls for an 'OVERSIZE LOAD' sign on top or on the front and rear.
- Trailer length: C.G.S. § 14-262(c) sets 45′ for single units and 48′ for semitrailers; a 48′–53′ trailer with no more than 43′ from kingpin to rear axle may run only on listed routes. The CTDOT FAQ lists 53′ without the route limit.
- The overhang pilot rule (over 25′ from the last visible support) does not say where the pilot car runs, so it is shown as a card, not an escort band.
- CTDOT publishes no general permit axle-weight table in the sources checked; posted and non-posted bridge restriction lists limit permitted weights.

Roads & authorities
A CTDOT permit covers only its route on state roads. Local, toll, private and facility roads need their own approval.
When a permit is needed
Loads over legal limits need a Connecticut oversize/overweight permit. A single-trip permit usually covers one trip within three days.
Superloads
Loads over 150′ long, 16′ wide, 16′ high or 200,000 lb are superloads. They need a route survey and more coordination with CTDOT.
Superload
CTDOT generally treats a move as a superload when it exceeds 150′ long, 16′ wide, 16′ high or 200,000 lb. Superloads move at night only and typically need Connecticut State Police escorts. Allow extra review time.
Superload application steps
For a superload, the carrier must also: Get a certified Connecticut route survey by a Connecticut-based surveyor within one week before the move. Get all necessary encroachment permits. Pass an enforcement inspection 1–2 days before the move and a same-day Level 7 inspection. Apply at least five business days before the move.

Special permits
Divisible-load, annual nondivisible, milk, radioactive, industrial and manufactured-goods permits each have their own conditions. Single-trip rules do not carry over to them.
Manufactured housing up to 14′ wide
For housing units up to 14′ wide and 14′1″ high (CTDOT 2020 guidelines): Daylight travel only, Monday–Friday. Over 12′ wide: no travel 6:30–9 a.m. or 4–6 p.m.
Manufactured housing over 14′ wide
Housing units over 14′ (up to 16′) wide, or over 14′1″ high: Night only, 9 p.m.–4:30 a.m., Monday night through Thursday night. Maximum width 16′.
Housing night moves: survey and escorts
For night housing moves: Route survey for any unit over 14′1″ tall. At least 1 State Police escort following on divided highways. At least 2 miles between units over 14′ wide.
Annual indivisible permit
Connecticut-based carriers hauling construction equipment can get an annual indivisible load permit (May 1–April 30). Each trip still needs a no-fee route authorization.
Self-propelled construction vehicles (annual)
Self-propelled construction vehicles qualify for an annual indivisible load permit up to these gross weights (axle and spacing limits apply too): 3 axles: 92,000 lb. 4 axles: 110,000 lb. 5 axles: 114,500 lb. 6 axles: 115,000 lb. Heavier units may still qualify after an engineering analysis.

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 Connecticut registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.
Great Dane Freedom flatbed brochure — Drop-deck option: 20–26 in drop from the upper deck with a 40–34 in rear deck height, which gives the 60 in upper-deck planning height. Platform length, combined tare and tractor geometry are editable ODPermit assumptions.

We summarize official sources as of the dates shown, but rules change often and a summary can be incomplete or out of date. Only a permit issued by the state or local agency authorizes an oversize or overweight move, and that permit and the agency’s current rules control. Confirm limits, escorts, routes and travel times with the issuing agency before you move a load.
