Los Angeles is the registered base for 18,433 motor carriers, running 2,422,420 power units and 116,417 drivers between them. The local base is dominated by very small operators: 87% 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 Los Angeles carrier base in numbers
| Carriers registered locally | 18,433 |
|---|---|
| Single-truck operators | 15,945 (87%) |
| Fleets of 2 to 10 power units | 2,220 (12%) |
| Fleets above 50 power units | 64 |
| Carriers flagged for hazardous materials | 428 (2%) |
| Registrations added since 2025 | 1,204 (7%) |
| Last MCS-150 filed more than 24 months ago | 3,098 (17%) |
What the local carrier data shows
The local carrier data is heavily weighted toward small fleets: 87% of the records shown have one power unit, while 64 carriers report more than 50. Applicable federal requirements do not disappear because a fleet is small, but a one-truck business may have the owner handling driver files, vehicle records, drug-and-alcohol program tasks and registration work that a larger carrier assigns to dedicated staff.
MCS-150 currency runs well below the national average in this market: 17% of local carriers (3,098 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.
Hazmat presence sits below the national norm here (2% against 7%, or 428 carriers), which pulls registration, training records and security planning into scope alongside the usual driver and vehicle files.

DOT compliance questions for Los Angeles
Do Los Angeles port trucks have separate terminal requirements?
Yes. The Port of Los Angeles publishes truck and Clean Truck Program requirements in addition to California and federal motor carrier obligations.
Can Clean Truck Check apply to an out-of-state truck in Los Angeles?
CARB says the program can cover affected heavy-duty vehicles operating on California public roads even when they are registered outside California. Check current scope and exemptions.
Are short Los Angeles drayage trips automatically exempt from ELD rules?
No. The carrier must confirm that the driver and operation meet every condition of a valid exception and keep the required time records.
What records support a Los Angeles port trip?
Useful evidence includes dispatch, appointment, gate, interchange, ELD, fuel, delivery and defect or repair records.
What should a Los Angeles carrier include in a compliance audit?
Include federal carrier records, driver files, testing and Clearinghouse work, HOS, maintenance, California emissions records and terminal handoffs.
