Do I need a trip permit or an annual permit?
A single-trip permit if the move is one-off or you make fewer than 4-6 trips into the state per year; an annual permit if you operate regular routes through the state. Annual breaks even around 4-6 trips per year and is cheaper above that.
Trip permits cover one specific movement — origin, destination, route, dates. They're issued in 24-72 hours, cost $20-$60 per state, and expire after the trip. Useful for one-off heavy/oversize moves and for testing a new lane before committing.
Annual permits cover all movements in the state for 12 months. Cost varies $50-$500 by state and weight class. The break-even depends on state pricing — in New York HUT or KYU the break-even is closer to 3-4 trips; in lower-tax states it's 6-8.
Operational rule of thumb: if you're running a regular lane through the state, file the annual and don't think about it again until renewal. If you're a one-off or seasonal operator, the trip permit avoids overcommitting and lets you cap exposure to known trips.
Carriers running multi-state lanes typically end up with a mix — annuals for the recurring states (NY, KY, NM, OR), trip permits for the occasional ones. Permit-management software or a filing service handles the calendar so renewals don't lapse mid-year.
