Seventeen reference guides for owner-operators and dispatchers who need the answer now, not a brochure. Every state rule and fee in them is read off an official state DOT publication and carries the date it was checked.
What each state DOT actually charges for a single-trip OS/OW permit — all 48, and why thirteen of them cannot be reduced to one number. Searchable, sortable, every figure dated and linked to its source.

12 min read · TexasEach state's figures carry their own verification date. We re-read the source fee schedule on a rolling cycle and republish when a DOT changes a number, so a stale figure is dated rather than silently wrong.
Because we have not yet verified that state's figure against its own DOT publication. Publishing an estimate that looks authoritative is how every other permit blog ends up quoting numbers that are years out of date. Call us and we will price any state today.
No. Every figure in these guides is the state DOT's own fee. Permigo's flat $20 service fee per state permit is separate and always shown separately.
$20 flat per state permit. A permit agent answers, 7am–7pm CT, seven days a week.
