California Commercial Truck Insurance Requirements

Q: What is an MCS-90 and do I need one?

The MCS-90 is a federal endorsement guaranteeing the public the FMCSA minimum coverage. Interstate for-hire carriers must carry it; we file it with your trucking policy.

California commercial truck insurance requirements start with federal FMCSA public-liability minimums — $750,000 for most general freight, $1,000,000 for oil and certain commodities, and up to $5,000,000 for hazardous materials — plus an MCS-90 endorsement for interstate for-hire carriers. Intrastate California carriers also need a CA DMV Motor Carrier Permit with matching liability on file. Typical for-hire premiums run roughly $9,000–$16,000 per power unit per year (illustrative ranges, not a quote). Insurance City is a Stockton independent brokerage that places trucking coverage statewide in English and Spanish, with no broker fees on standard policies (Stockton & San Jose offices).

What are California commercial truck insurance requirements?

To operate a commercial truck in California you generally need (1) primary auto liability at or above the FMCSA floor for your commodity, (2) an MCS-90 endorsement if you are interstate for-hire, (3) a USDOT number for trucks over 10,001 lbs in commerce, (4) MC authority when you haul for hire across state lines, and (5) a California Motor Carrier Permit with proof of insurance on file for intrastate work. Cargo, physical damage, bobtail, and trailer interchange are not always “required by FMCSA,” but shippers, brokers, and lenders usually demand them before you can haul.

Requirement	Who needs it	Typical minimum
FMCSA public liability	Interstate for-hire / many regulated carriers	$750K / $1M / up to $5M hazmat
MCS-90 endorsement	Interstate for-hire	Filed with the liability policy
CA Motor Carrier Permit	Intrastate commercial carriers	Proof of insurance + CA number
USDOT / MC authority	Commercial trucks >10,001 lbs; interstate for-hire	USDOT always; MC when for-hire interstate

How much does commercial truck insurance cost in California?

Commercial truck insurance in California typically costs $9,000–$16,000 a year per power unit for for-hire authority holders, $5,000–$9,000 for leased owner-operators, and $12,000–$20,000 for dump and aggregate hauling. Rates depend on radius, cargo, driver records, and loss history — FMCSA data puts the average cost of an injury truck crash near $200,000, which is what your liability limits are protecting against. Typical annual per-unit ranges:

Operation	Typical annual / unit
Owner-operator (leased)	$5,000–$9,000
Authority / for-hire ★	$9,000–$16,000
Dump / aggregate hauling	$12,000–$20,000

Typical California ranges, not a quote. Your premium depends on units, drivers, radius, cargo, and loss runs.

What are the FMCSA insurance requirements for California truckers?

FMCSA insurance requirements set the liability floor you must show to keep authority: $750,000 public liability for most general freight, $1,000,000 for oil and certain commodities, and up to $5,000,000 for hazardous materials (FMCSA). Interstate for-hire carriers must carry and file an MCS-90 endorsement; intrastate California carriers file proof with the CA DMV Motor Carrier Permit program. Details: FMCSA liability requirements, MCS-90 and BMC-91.

What coverages does a California trucking policy include?

A complete California trucking program combines five coverages: primary liability (the FMCSA-required $750,000+), physical damage on tractor and trailer, motor truck cargo (commonly a $100,000 limit), non-trucking/bobtail liability for off-dispatch driving, and trailer interchange for trailers you pull but do not own.

Primary liability — the FMCSA-mandated $750K+ that covers damage you cause to others.
Physical damage — collision and comprehensive on your tractor and trailer.
Motor truck cargo — the freight you haul, commonly $100,000 limits.
Non-trucking / bobtail liability — for owner-operators driving off dispatch.
Trailer interchange — when you pull trailers you do not own.

Do I need a DOT number and MC authority in California?

Any truck over 10,001 lbs used commercially needs a USDOT number, and for-hire interstate carriers also need MC operating authority. Intrastate California carriers need a CA number and a Motor Carrier Permit. See box truck DOT and insurance requirements and dump truck and aggregate hauling insurance.
