Legal Dimensions for Connecticut Oversize Load Permits


  • 48′ trailer.
  • Note: A 53′ semi-trailer is permitted on Interstate and Designated Highways if the    kingpin-to-rear-axle distance is within 43′. For single-piece OD  load permits, kingpin setting is irrelevant. However, for multiple-piece loads, the 43′ maximum applies, even for legal-sized extra pieces.
  • Traveling with a 53′ semi-trailer without a permit and a kingpin setting exceeding 43′ may result in a $750 fine when empty, unless the return trip is specified on the permit.


Trailers exceeding 48′ in length require a permit. Overhangs of over 4′ must be flagged during the day and lighted at night.




13′-6″ (Note: CT will not issue a permit for overheight for any kind of a building.)


80,000 Gross

  • Single – 22,400
  • Tandem – 36,000
  • Tridem – 42,500

Routine Permit Limits at Connecticut






14′ (Route survey required for height over 14′); 13′-6” is the maximum height for any kind of building.


  • Single – 22,500
  • Tandem – 45,000
  • Tridem – 67,500

Connecticut allows axle weights up to 25,000 pounds on a single axle, as long as the manufacturer’s rating is not surpassed and the overall gross weight remains within the specified limits for 5, 6, or 7 axles.

Over 14′ wide, 14′ high or 120′ long is considered a Super Load. Over 140,000 lbs requires an engineer review.

Note: the maximum superload width in Massachusetts is 16 feet.
