The short answer
Alaska trucks that never leave the state: the USDOT number when it is 10,001 lbs or more, seats 9 or more for hire, seats 16 or more or carries placard-level hazmat.
Alaska intrastate trucks at 10,001 lbs GVWR/GVW and up (or 9+ passengers for hire, 16+ otherwise, or placarded hazmat) must show name + USDOT number on both sides, readable from 50 feet. Note: commercial-fishing-license holders running trucks of 26,000 lbs or less outside Anchorage/Fairbanks (no hazmat, 15 or fewer passengers) are exempt under 17 AAC 25.210(j).
Trucks that cross a state line, or haul freight that starts or ends in another state, follow the federal rule instead: the USDOT number and your legal name when it is 10,001 lbs or more, carries placard-level hazmat, seats 9 or more for hire or seats 16 or more (49 CFR 390.21T(b)(2)).

Seven Alaska trucks, run through the checker
Each verdict below is what our free compliance checker returns for that truck using the verified Alaska and federal rules. Where one changed fact flips the answer, we show the flip, because that is usually where Alaska carriers get caught.
1. A 9,000-lb plumber's cargo van on Anchorage service calls, Alaska only
9,000 lbs GVWR · own tools and parts · Alaska only
Not required
At 9,000 pounds it is under the 10,001-pound Alaska line and it carries general freight with no placard, so no verified Alaska or federal rule reaches it.
2. A 14,000-lb GVWR service truck on landscaping jobs around Anchorage, Alaska only
14,000 lbs GVWR · own equipment · Alaska only
USDOT number required
The Alaska rule reaches this truck because it is 14,000 pounds, over the 10,001-pound line. The checker returns the USDOT number, both sides. On the door that reads: USDOT 1234567.
3. A 10,000-lb GVWR cutaway box van delivering furniture for pay, Anchorage only
10,000 lbs GVWR · paid freight · Alaska only
Not required
At 10,000 pounds it is under the 10,001-pound Alaska line and it carries general freight with no placard, so no verified Alaska or federal rule reaches it.
Flip one fact: At 10,001 pounds, one pound more, the same truck needs the USDOT number.
4. A 33,000-lb tandem dump truck for a Fairbanks contractor, Alaska only
33,000 lbs GVWR · paid hauling · Alaska only
USDOT number required
The Alaska rule reaches this truck because it is 33,000 pounds, over the 10,001-pound line. The checker returns the USDOT number, both sides. On the door that reads: USDOT 1234567.
Flip one fact: Rated at 10,000 pounds, the same truck stays under the Alaska 10,001-pound line: at 10,000 pounds no verified Alaska rule reaches it.
5. A 15-passenger hotel shuttle van in Anchorage, no fare charged
15 seats including the driver · passengers, not for hire · 9,500 lbs GVWR · Alaska only
Not required
At 9,500 pounds it is under the 10,001-pound Alaska line and 15 seats is under the 16-passenger trigger for private carriers, so no verified Alaska or federal rule reaches it.
Flip one fact: With 16 seats including the driver, the same van needs the USDOT number.
6. A 12-passenger paid airport shuttle, Anchorage only
12 seats · passengers for pay · 9,500 lbs GVWR · Alaska only
USDOT number required
The Alaska rule reaches this truck because it seats 12, meeting the 9-passenger trigger and hauls for hire. The checker returns the USDOT number, both sides. On the door that reads: USDOT 1234567.
Flip one fact: Haul only your own goods in the same truck and at 9,500 pounds no verified Alaska rule reaches it.
7. A 14,000-lb placarded propane bobtail, Alaska only
14,000 lbs GVWR · placard-level hazmat · Alaska only
USDOT number required
The Alaska rule reaches this truck because it is 14,000 pounds, over the 10,001-pound line and carries placard-level hazmat. The checker returns the USDOT number, both sides. On the door that reads: USDOT 1234567.
The checker weighs rating, registered and actual weight, operation, for-hire status, cargo, passenger count and farm status. It does not model axle count or vehicle type, so if your truck is unusual, confirm with Alaska DOT&PF — Measurement Standards & Commercial Vehicle Compliance.
What goes on the door in Alaska
- One marking, both sides of the power unit: USDOT 1234567, which is the USDOT number.
- No inch minimum in Alaska. The legal standard is a color that contrasts with the truck and letters readable from 50 feet in daylight. We cut 2-inch letters, which clears that bar on any door.
- One set covers both rules. The Alaska markings and the federal markings are the same two items, so an Alaska-only truck that later picks up an out-of-state load does not need new decals.
Across the Alaska line
The Alaska line only matters while the truck stays home. One job in Washington, or one load that starts or ends out of state, makes it interstate commerce, and the federal 10,001-pound rule applies no matter where either state draws its own line. For a truck that works near the border it helps to know how the neighbors differ for their own in-state trucks:
- Washington: the federal 10,001 pounds even in-state.
Neighbor lines come from the same verified rule files the checker uses; each state's page has its citations.
Who enforces it in Alaska
Door markings in Alaska are the business of Alaska DOT&PF — Measurement Standards & Commercial Vehicle Compliance. Questions about your registration or number: (907) 365-1210, agency site. The federal side, USDOT numbers and the MCS-150, is the FMCSA Alaska Division: (907) 271-4068, MCAKOFF@dot.gov. A marking violation is written at the roadside and follows the carrier on the inspection report, which is why it is worth getting the two lines right the first time.
For the marking mistakes inspectors catch most often, see USDOT marking mistakes that fail roadside inspections.
Where the Alaska rule comes from
- 17 AAC 25.210(d) — intrastate USDOT identification & marking per 49 CFR 390.21; CMV as defined in 49 CFR 390.5 (10,001+ lbs)
- 49 CFR 390.21(c)-(d) — both sides, sharp contrast, legible 50 ft daylight
- 17 AAC 25 official DOT&PF compilation — (incl. 25.210(j) fishing exemption, 25.210(e) biennial MCS-150)
- 49 CFR 390.21T — the federal marking rule for interstate carriers
