San Francisco is the registered base for 2,346 motor carriers, running 22,653 power units and 15,232 drivers between them. The local base is dominated by very small operators: 79% run a single power unit, so in most cases the owner is also the safety manager, the designated employer representative and the person answering an audit letter.

The San Francisco carrier base in numbers
| Carriers registered locally | 2,346 |
|---|---|
| Single-truck operators | 1,845 (79%) |
| Fleets of 2 to 10 power units | 421 (18%) |
| Fleets above 50 power units | 21 |
| Carriers flagged for hazardous materials | 61 (3%) |
| Registrations added since 2025 | 206 (9%) |
| Last MCS-150 filed more than 24 months ago | 421 (18%) |
Where San Francisco differs from the national picture
MCS-150 currency runs well below the national average in this market: 18% of local carriers (421 in total) have not filed inside 24 months, against 38% nationally. Carriers with an overdue MCS-150 should update the filing to keep the registration current.
79% of local carriers run a single power unit and 21 run more than fifty. The federal duties are the same either way, but a one-person operation carries them without a safety office.
Hazmat presence sits below the national norm here (3% against 7%, or 61 carriers), which pulls registration, training records and security planning into scope alongside the usual driver and vehicle files.

DOT compliance questions for San Francisco
Who handles extralegal truck permits in San Francisco?
The Port of San Francisco directs carriers to the San Francisco Municipal Transportation Agency for extralegal truck permits. Check the current route and load details.
Does a California permit replace federal vehicle safety requirements?
No. Permit compliance is separate from driver qualification, HOS, inspection, maintenance, securement and other applicable motor carrier duties.
How should a carrier plan a downtown San Francisco delivery?
Check the truck route, dimensions, loading location, customer window, safe stopping and available driver hours before dispatch.
Can Clean Truck Check affect a truck visiting San Francisco?
It can if the vehicle falls within current CARB scope. Registration outside California does not by itself create an exemption.
What records help defend an urban delivery log?
Dispatch, customer appointment, toll, fuel, proof-of-delivery and route records can support the driver's ELD or time record.
