Connecticut oversize permit rules
What Connecticut charges for a single-trip OS/OW permit, the limits that trigger one, and the escort thresholds — read from the state’s own publication. This rule has been in effect since 2026-07-06; we last read the source on 2026-07-06.
Oversize permit
$42
One price for a single-trip permit, whatever the dimensions. A 9-foot-wide load and a 16-foot-wide load pay the same.
Overweight permit
From $42
Scales with weight — there is no single figure.
A load that is both oversize and overweight pays this fee only, not both.
+ $20 Permigo service fee per permit, state fees at cost.
Legal limits
Exceed any one of these in Connecticut and you need a permit for this state.
