> When an owner-operator leases on to a motor carrier, the carrier’s UCR covers the operation. Standalone authority means standalone UCR. Here’s how lease, authority, and 49 USC §14504a interact.

## TL;DR

> A leased-on owner-operator running exclusively under another carrier’s MC number is covered by the lessor carrier’s UCR. Keeping standalone authority active means a separate UCR is owed every year, regardless of activity.

## Key takeaways

- UCR is keyed to the legal entity holding active interstate authority — not to who is driving.
- Long-term leased trucks (30+ days under 49 CFR Part 376) count toward the lessor carrier’s UCR tier.
- An active MC number in SAFER triggers a UCR obligation even if the carrier is leased out 100%.
- Trip-leased equipment is covered by the trip-lessor for the duration of that load.
- Going independent triggers an immediate UCR obligation — not prorated, not deferred.

## FAQ

### I lease on to a motor carrier under their authority. Do I owe UCR?

No, not as long as you’re running exclusively under the lessor carrier’s MC number and you don’t hold your own active interstate operating authority. The carrier whose authority is on the door is the registrant for UCR purposes under 49 USC §14504a, and its UCR covers the truck while it’s under that lease.

### What if I keep my own MC number active while leased on?

Then you owe a separate UCR filing. UCR is keyed to the entity holding interstate FMCSA authority — not to who is dispatching the load. If your MC number is active in FMCSA SAFER, the UCR Plan considers you a registrant, and you owe an annual UCR even when you’re running 100% under another carrier’s authority.

### How does the lessor carrier count my truck for their UCR tier?

If your truck is under a long-term lease (30 days or more) operating under the carrier’s authority, the carrier counts it in their CMV total. That is true under FMCSA’s leased-equipment rules at 49 CFR Part 376 and the UCR Plan’s counting guidance. Trip-leased and short-term equipment count differently — the lessor carrier’s compliance team should be tracking the distinction.

### What happens to my UCR obligation when I drop the lease?

The day you go back to running under your own MC number, you’re a registrant in your own right and owe UCR for the current year (if you don’t already have one). The dormant-authority lease window doesn’t protect you once you reactivate. File for the current year as soon as you go independent.
