Connecticut trucking permits
Trip, fuel and oversize/overweight permits for Connecticut — what the state requires, how it prices them, and how to get them filed.
What Connecticut permits cost
The state's own fee, plus what we charge to prepare and file it. Your total depends on the trip, so the quote is the number that counts — these are the floors we hold on file.
| Permit | Connecticut fee | Our fee |
|---|---|---|
| Trip Permit | from $50 | $29 |
| Fuel Permit | from $32 | $29 |
| Oversize / Overweight | from $42 | $39 |
A handling fee applies to each permit line. Nothing is charged until you have seen the total.
Fees and limits on this page were last checked in September 2026. States change fee schedules, legal limits and office hours without notice, and some fees depend on details we only know once you tell us the trip. Connecticut is the authority, not this page — treat these as a guide and the quote as the number.
When you need an oversize permit in Connecticut
Width and gross weight are federal everywhere — over 102 inches wide or 80,000 lbs and you need a permit in Connecticut and in every other state. What changes at the state line is height, trailer length and what the axles may carry.
- Height
- 13' 6"
- federal baseline 13' 6"
- Semi-trailer length
- 53'
- federal baseline 53'
- Tandem axle
- —
- federal baseline 34,000 lbs
Connecticut holds to the federal figures on all three, so a load legal on the interstate is legal here.
Overhangs, single and tridem axles and the full table are on the Connecticut regulations page.

Who issues the permit, when they are open, and where they take applications. We deal with them so you do not have to — but if you would rather call them yourself, this is the desk.
