The USDOT number on the power unit is not optional. The July 2000 marking rule is why {{USDOT}} is on our door before the truck rolls
The July 2000 marking rule put the USDOT number on the power unit before it goes into service. Our door shows {{USDOT}} because that is the identification rule.
What the notice actually said
The door shows {{USDOT}} before the truck moves because that is the rule. Effective July 3, 2000, new interstate carriers file the MCS-150 and mark power units with the USDOT number before placing them in service, not 90 days later.
ICC numbers got a two-year sunset to July 3, 2002. Use the legal name or a single trade name as on the MCS-150. A mismatched door is how double-broker fog starts at the gate.
SAFER still starts with that number, and enforcement and the public use it. The 2000 rule concerns power units as stated; confirm the current 390.21 for the full marking picture, including what belongs on a trailer.
A leased truck whose number does not match the carrier operating it is a gift to a roadside inspector. Do not buy a "leased MC" sticker pack.
The older 90-day unmarked allowance is what this rule ended for new operations. Anyone selling a grace period for a blank door is quoting a dead sentence.
What it changes on Monday
See also do not sell the USDOT number. We do not rent {{USDOT}}, and we do not put {{MC}} on someone else's door for a fee.
The packet still starts with the number on the door: see the broker packet. About the named carrier: About Royser.
Lease and owner-operator onboarding includes the marking conversation: owner operators. Dispatch will not send a truck whose door does not match the authority on the rate confirmation.
Shippers who want the actual truck and not a remix: Price a lane.
What we will and will not do
We will mark the power unit with USDOT {{USDOT}} and MC# {{MC}} before it rolls. We will not rent those numbers or run a blank door on a "90-day" story this rule ended.
We will not put a trade name on the door that is not on the MCS-150. One name, matching the census form.
Packet questions: +1 (224) 877-0350. A person at the desk. The number on the door is the number in SAFER.

FAQ
Can we run 90 days unmarked?
That older allowance is what this rule ended for new operations. Mark the power unit before it is placed in service.
What about a trailer USDOT number?
The 2000 rule is about power units as stated. Confirm the current 390.21 for the full marking picture.
What about the trade name?
One name, matching the MCS-150. A second slogan on the door that is not on the census form is how identification fog starts.
What is your number?
USDOT {{USDOT}}. MC# {{MC}}. Both belong on the truck we operate, not on a rented door.
