Does a Utah truck need a USDOT number for in-state work?
Yes. UDOT says in-state carriers need a USDOT number. It gives no weight line; Utah's statute makes an in-state commercial vehicle one of 26,001 lb or more (16,001 lb with a driver under 18), and that is the line the adopted federal rules attach to.

The rule in Utah
Who it covers: Businesses using a vehicle 'for business, compensation, or profit' only within Utah, i.e. for-hire and private carriers, once the vehicle meets the intrastate commercial vehicle definition.
The weight line: A Utah intrastate commercial vehicle is one of 26,001 lb or more (rated or actual, single or combination) driven by someone 18 or older; 16,001 lb or more if the driver is under 18; plus larger passenger vehicles and placarded hazmat. UDOT's USDOT page does not itself state a weight line.
Exemptions the state lists:
- Passenger vehicles designed for 12 or fewer passengers and rated under 13,000 lb are excluded from the adopted federal rules (Utah Admin. Code R909-1-3(1))
“Companies that operate commercial vehicles transporting passengers, or hauling cargo, in intrastate/interstate commerce must be registered with the FMCSA and must have a USDOT Number, including freight brokers.” source
“has a manufacturer's gross vehicle weight rating or gross vehicle weight, or gross combination weight rating or gross combination weight of 26,001 or more pounds, whichever is greater, and is operated by an individual who is 18 years old or older” source

Safety rules for in-state trucks
Utah incorporates 49 CFR Parts 350-384, 385.4, 387-399 and 40 (as amended through June 22, 2023) and applies them to intrastate commercial motor carriers as defined in Utah Code 72-9-102(3), except the federal age rule and 391.49 for intrastate drivers. (Utah Admin. Code R909-1-3)
- Intrastate drivers may be 18 (21 for placarded hazmat or 16+ passengers).
- Intrastate drivers may get exceptions to the federal physical qualification standards through the Driver License Division.
- For drivers under 18, the intrastate commercial vehicle line drops to 16,001 lb.
The federal lines, which apply in Utah too
- 10,001 lb and interstate commerce: a USDOT number, a medical card, a driver qualification file, the hours-of-service rules and daily inspections (49 CFR 390.5).
- 26,001 lb: a CDL, for a single vehicle or a combination towing more than 10,000 lb (383.5). The CDL rules cover in-state driving as well (383.3), and drug and alcohol testing follows the CDL (382.103).
