DOT legal transport regulations by state
Select a state for its legal weight limits, maximum dimensions, and permit office details. Anything over those limits needs an oversize/overweight permit, which you can order online.
What each state regulates
Every state sets its own maximum weight, width, height and length for a commercial vehicle on its roads, along with limits on front and rear overhang and on what each axle group may carry. Federal law fixes only a few of these on the Interstate system; the rest are the state's to decide, and they differ.
The state pages below give the current figures, the axle weight table, and the office that issues permits when you are over them — its hours, its phone number and its portal.
When you need an oversize or overweight permit
The moment your load exceeds any one of a state's limits, that state needs a permit before you cross it — and being legal in the state you loaded in says nothing about the next one. A trailer that is legal in Texas can be over height in Pennsylvania on the same load.
Rather than check fifty tables by hand, put the route and the load into the quote and every state you pass through is measured against its own limits, with the permits you need priced for each.
