Delaware oversize permit requirements
Delaware states one rule more plainly than any other state states anything: all loads that are reducible must be reduced, no exceptions. There is no negotiating a permit for something that could have travelled in two trips. Carriers used to states where a marginal case can be argued will not find room here.
The rest is compact, like the state. Permits run five days, movement is sunrise to sunset including weekends, and the holiday calendar includes Good Friday — one of the few states to list it. The holiday shutdown starts at noon the day before and does not lift until nine the morning after, so a single holiday removes the best part of three days.
The figures hold two surprises for a state this small. The routine tridem allowance is sixty-nine thousand pounds, higher than almost anywhere on the seaboard, and poles and steel travel legally to seventy feet with five feet of rear overhang. Working the other way, legal height drops to thirteen feet on non-designated highways — six inches under the national figure, which is enough to catch a standard trailer that turns off the main road. Routine permits run to a hundred and twenty feet, fifteen feet wide and fifteen feet high, with a route survey required at fifteen feet and above.

Delaware permits, answered
Will Delaware permit a load that could be split?
No. All loads that are reducible must be reduced, without exception — there is no marginal case to argue here.
How long does the Delaware holiday shutdown last?
From noon the day before until 9 AM the day after, so a single holiday removes the best part of three days. Good Friday is on the list, which few states do.
Why is my 13-foot-6 load overheight in Delaware?
Because legal height drops to 13′ on non-designated highways. A standard trailer that is legal on the main road stops being legal when it turns off.
Can an oversize load travel at the weekend in Delaware?
Yes — sunrise to sunset, weekends included.
How heavy can a tridem be on a Delaware permit?
69,000 lb, which is among the highest routine tridem allowances on the eastern seaboard.
Crossing more than Delaware?
A permit is per state. If the route leaves Delaware, these are the states it most likely enters.
