Kentucky trip and fuel permits

A truck can run Kentucky legally without apportioned plates or an IFTA license, but only on the state's own temporary permits, bought before the trip. Here is each trip permit and fuel permit, what it stands in for, what the state charges, and where to buy it, every fact sourced.

Kentucky sells its temporary credentials, including the one-time KYU weight-distance permit for carriers not making regular Kentucky trips, through the Transportation Cabinet's online Motor Carrier Permits portal. The cabinet confirms the permits exist on its public pages but prices them inside the portal itself, so the fee only displays once you start a purchase against a USDOT number.

The trip permit (registration side)

This credential answers for registration. Without it, a vehicle whose cab card does not list Kentucky has no legal registration standing in the state.

Permit
Temporary permits via the KYTC Motor Carrier Permits portal
Stands in for
IRP apportioned registration listing Kentucky, and the KYU weight-distance license for occasional trips
Fee
The Kentucky Transportation Cabinet does not publish temporary permit prices on its public motor carrier pages; prices display inside the Motor Carrier Permits portal once a purchase is started against a USDOT number.
Valid for
Not published on the cabinet's public pages; the portal shows validity at purchase.
Who needs it
Carriers operating into or through Kentucky without Kentucky apportioned registration or the applicable Kentucky tax licenses.
Where to buy
KYTC Motor Carrier Permits portal (apps.transportation.ky.gov); Commercial permit service companies (service fees apply)
Statute
The cabinet's public pages link to the permit portal without citing the authorizing statute alongside it.

The fuel permit (tax side)

This credential answers for the state's highway or fuel tax when there is no IFTA license (or, in the weight-distance states, no tax account) behind the truck.

Permit
One-time temporary KYU permit (weight-distance); fuel tax runs through IFTA or KIT
Stands in for
KYU weight-distance license for a single trip (Kentucky's per-mile highway tax on vehicles with a combined license weight greater than 59,999 pounds); Kentucky publishes no separate flat-fee diesel trip permit, and fuel tax for interstate carriers runs through IFTA
Fee
The cabinet's KYU page confirms a one-time temporary KYU permit can be purchased per truck for carriers not making regular trips through Kentucky, but the price is published only inside the Motor Carrier Permits portal.
Valid for
Not published on the cabinet's public pages; the portal shows validity at purchase.
Who needs it
Carriers over the KYU weight threshold that are not making regular trips through Kentucky and have no KYU license.
Where to buy
KYTC Motor Carrier Permits portal (apps.transportation.ky.gov); Commercial permit service companies (service fees apply)
Statute
KRS 138.660 (weight-distance tax)

Worth knowing

Data honesty note: fee and duration fields stay null here because the Kentucky Transportation Cabinet publishes no public temporary permit fee schedule; anything a permit service quotes above the portal price is a service fee. Carriers making regular Kentucky runs should open KYU, IFTA, and IRP accounts with the Kentucky Trucking Application (TC 95-1) instead of buying repeated temporary permits.

Where these fit in the Kentucky permit stack

Temporary permits are the exception path. The standing credentials they replace are IRP apportioned registration and the Kentucky IFTA license. Oversize loads use a different permit family entirely, covered in Kentucky oversize and overweight permits, and the full picture of every state permit lives in Kentucky trucking permits.

Frequently asked questions

How much does a Kentucky permit cost?

The state does not publish flat fees on the page this site cites; the fee rows above carry the state's own notes on how each permit is priced instead of a guess.

Do I need a trip permit or a fuel permit for Kentucky?

Usually both, and they are separate purchases. The trip permit stands in for apportioned (IRP) registration and the fuel permit stands in for the IFTA license. If your cab card lists Kentucky and your IFTA decals are current, you need neither; the tables on this page carry each permit's terms with the official source.

When does buying temporary permits stop making sense?

Temporary permits price a single trip. A carrier running Kentucky lanes on a regular schedule comes out ahead adding the state to its IRP cab card and holding an IFTA license, because permit fees repeat on every trip while the annual credentials do not.

Can I buy these permits after entering the state?

No. Each credential on this page must be in place before the vehicle operates on Kentucky highways, and enforcement happens at roadside inspections and weigh stations. Buying from the state's own channel before the trip is the cheapest clean path.

Are permit-service prices the state fee?

No. Wire services and permit companies resell state permits with a service markup. The fees on this page are what Kentucky itself charges on its primary pages; anything above that is the middleman's fee, not the state's.
