Combined Single Limit vs Split Limits on Commercial Auto in California

Work truck that may need a combined single limit on a California commercial auto policy

A combined single limit is one dollar amount for bodily injury and property damage from one accident. Split limits are three numbers: per person, per accident, and property damage. A contract that says "$1,000,000 combined single limit" is asking for that single bucket. Call 209-670-1556. Se habla español.

What is a combined single limit on commercial auto?

A combined single limit is one amount available for bodily injury and property damage together from one accident. The policy does not split that accident into a per-person bucket, a per-accident bodily-injury bucket, and a separate property-damage bucket. Whatever the accident uses comes out of that one limit until the limit is exhausted.

Definition. Combined single limit, often shortened to CSL, means the declarations show one liability number for the auto, and that number can pay injury claims and property-damage claims from the same crash. If the number is $1,000,000, the accident can use up to $1,000,000 in total for those liability damages. It is a limit on the policy, not a price for the policy.

People search the phrase "$1 million combined single limit" because a job packet, a shipper packet, or a city contract printed it. The search is about matching words on a certificate to words on a contract. It is not a search for the smallest legal policy. The commercial auto page is the product hub. The difference between a personal auto policy and a business-use policy is on the commercial auto versus personal business use page.

The contract is the source of a combined-single-limit figure on a job packet. Vehicle Code section 16056 is the source of the state minimum split.

What are split limits?

Split limits are three numbers: bodily injury per person, bodily injury per accident, and property damage. Each number caps its own part of the accident. Money left in the property-damage number cannot be moved over to pay a larger bodily-injury claim, and the reverse is also true.

A policy written 30/60/15 means $30,000 for bodily injury to one person, $60,000 for bodily injury to all persons in one accident, and $15,000 for property damage. Those three caps stand side by side. An accident that injures one person for more than the per-person number stops at that number even if the per-accident number is higher. An accident that wrecks a building stops at the property-damage number even if almost none of the bodily-injury numbers were used.

California's financial-responsibility statute uses this three-part shape for the minimum. A combined single limit is a different shape. A contract can ask for either shape. Reading the contract's words is the first step, before anyone argues about which shape is "enough."

The contract is the source of a combined-single-limit figure on a job packet. Vehicle Code section 16056 is the source of the state minimum split.

Why do contracts ask for a $1,000,000 combined single limit?

General contractors, cities, and shippers write the phrase because they want one accident limit that can pay injury and property damage without three smaller caps. The certificate has to match the words in that contract. A split-limit policy at the state minimum does not say $1,000,000 combined single limit.

The dollar figure in the contract is a requirement the other party wrote. It is not a quote and it is not a statewide mandate that every work truck carry $1,000,000. A landscaper's subcontract, a city's vendor packet, and a broker's load confirmation can each print a different number. Some say $1,000,000 combined single limit. Some say $1,000,000 per occurrence and then name a general-liability policy, which is a different contract line from auto liability. Match the line that says automobile, hired and non-owned, or commercial auto, not the line that says general liability.

If the contract also asks for an additional insured, a primary and noncontributory endorsement, or a waiver of subrogation, those are separate sentences from the limit. A higher limit sitting over the auto policy is the job of a commercial umbrella. See the commercial umbrella page for small business when the contract's total is above the auto policy's own number.

The contract is the source of a combined-single-limit figure on a job packet. Vehicle Code section 16056 is the source of the state minimum split.

How do you read the auto line on a certificate?

On a standard certificate of liability insurance, the automobile liability block is the place that shows either one combined single limit or the three split numbers. The certificate describes the policy. It does not replace the policy, and a blank box is not the same as a limit.

Look for the automobile row, not the general-liability row. A combined single limit usually appears as one figure in the combined-single-limit column. Split limits usually appear as separate figures for bodily injury, each person and each accident, and for property damage. The policy number, the effective dates, and the name of the insured have to match the business that signed the contract. A certificate that shows only the state minimum split, while the contract says $1,000,000 combined single limit, is the mismatch that sends the packet back.

Hired auto and non-owned auto, when the contract asks for them, are checkboxes or endorsements about whose vehicle is covered. They are not a substitute for the dollar limit. Send the contract page that names the limit so the certificate can be built to that sentence.

What are California's minimum auto liability limits?

Vehicle Code section 16056 says a policy or bond issued or renewed on or after January 1, 2025, must provide at least $30,000 because of bodily injury or death of one person in one accident, $60,000 because of bodily injury or death of two or more persons in one accident, and $15,000 because of injury to or destruction of property of others in one accident. Those figures are limits, not a price.

Vehicle Code section 16056 says a policy or bond is not effective under section 16054 unless it meets one of the limit tests in subdivision (a), and unless the company rules in that section are met. Subdivision (a)(1) still states the older test: not less than $15,000 for bodily injury or death of one person, $30,000 for two or more persons, and $5,000 for property damage. Subdivision (a)(2) says that notwithstanding paragraph (1), for any policy or bond issued or renewed on or after January 1, 2025, the limits are not less than $30,000, $60,000, and $15,000 for those same three tests. Subdivision (d) says that for a policy or bond issued or renewed on or after January 1, 2035, the minimum liability coverage shall be increased by $20,000 for bodily injury or death for one person, by $40,000 for bodily injury or death for all persons, and by $10,000 for property damage. Subdivision (e) says the section became operative on January 1, 2025.

The state minimum is the floor for financial responsibility under that section. A job contract can sit far above the floor. Meeting 30/60/15 does not, by itself, meet a sentence that says $1,000,000 combined single limit.

When do federal minimums apply instead?

For motor carriers of property that the federal rule covers, 49 CFR 387.9 prescribes minimum levels of financial responsibility. The schedule sets $750,000 for for-hire interstate or foreign carriage of nonhazardous property in a vehicle with a gross vehicle weight rating of 10,001 pounds or more. Other rows in the same table set $1,000,000 or $5,000,000 for the hazardous cargo they describe.

Section 387.9 says the minimum levels referred to in section 387.7 are prescribed in Table 1, Schedule of Limits, Public Liability. The amount column is headed January 1, 1985. The schedule, as amended through 91 FR 45660 (July 21, 2026), reads:

Type of carriageCommodity transportedMinimum
(1) For-hire, in interstate or foreign commerce, GVWR of 10,001 pounds or moreProperty (nonhazardous)$750,000
(2) For-hire and private, in interstate, foreign, or intrastate commerce, GVWR of 10,001 pounds or moreHazardous substances, as defined in 49 CFR 171.8, transported in bulk in cargo tanks, portable tanks, or hopper-type vehicles; in bulk Division 1.1, 1.2, or 1.3 materials; in bulk Division 2.3, Hazard Zone A material; in bulk Division 6.1, Packing Group I, Hazard Zone A material; in bulk Division 2.1 or 2.2 material; or highway route controlled quantities of a Class 7 material, as defined in 49 CFR 173.403$5,000,000
(3) For-hire and private, in interstate or foreign commerce in any quantity, or in intrastate commerce in bulk only, GVWR of 10,001 pounds or moreOil listed in 49 CFR 172.101; hazardous waste, hazardous materials, or hazardous substances defined in 49 CFR 171.8 and listed in 49 CFR 172.101, but not mentioned in entry (2) or (4) of the table$1,000,000
(4) For-hire and private, in interstate or foreign commerce, GVWR of less than 10,001 poundsIn bulk Division 1.1, 1.2, or 1.3 material; in bulk Division 2.3, Hazard Zone A material; in bulk Division 6.1, Packing Group I, Hazard Zone A material; or highway route controlled quantities of a Class 7 material as defined in 49 CFR 173.403$5,000,000

These are financial-responsibility minimums for the carriage the row describes. They are not premiums. A local work truck that is not in interstate for-hire carriage of property is not automatically on row (1). A contract can still ask for $1,000,000 combined single limit even when the federal schedule does not.

How do CSL, split limits, and the state minimum compare?

A combined single limit gives one accident one number for injury and property damage together. Split limits give the same accident three caps. The state minimum in section 16056 is a split-limit floor for policies issued or renewed on or after January 1, 2025. A contract limit is whatever the other party wrote, and it can be a combined single limit well above that floor.

Who asks for itWhat one accident can use
Combined single limitA contract, a general contractor, a city packet, or a shipper that prints one auto liability number, often $1,000,000Bodily injury and property damage together, up to that one number
Split limitsA policy written as per person / per accident / property damage, including many personal auto policiesEach bucket only up to its own number. Unused property damage does not raise the injury cap
California minimumVehicle Code section 16056, for a policy or bond issued or renewed on or after January 1, 2025$30,000 one person, $60,000 all persons, $15,000 property damage. Not a $1,000,000 combined single limit

How does one accident use a combined single limit?

If the contract requires $1,000,000 combined single limit, one accident can use that amount for bodily injury and property damage together. A 30/60/15 split, the minimum in Vehicle Code section 16056 for a policy issued or renewed on or after January 1, 2025, caps property damage at $15,000 and one person's injury at $30,000. It does not read as a $1,000,000 combined single limit.

Walk it in words, with no premium. The subcontract says the auto liability on the certificate shall be $1,000,000 combined single limit. The truck backs into a loading dock and injures the dock worker. Injury and the broken dock are one accident. On a $1,000,000 CSL, both parts draw from the same $1,000,000 until that number is used up. On a 30/60/15 policy, the injury stops at $30,000 for that one person and the dock damage stops at $15,000. The contract asked for the first shape. The second shape does not reprint the contract's sentence.

If the same contract then asks for $2,000,000 total liability, the auto policy's $1,000,000 CSL may still be short of that second sentence. That is when the commercial umbrella is the next conversation, not a second guess at the state minimum.

The contract is the source of a combined-single-limit figure on a job packet. Vehicle Code section 16056 is the source of the state minimum split.

How do you ask for a commercial auto quote?

The quote starts with the vehicle and the sentence in the contract, and it ends when the certificate can show the limit that sentence names. These are the steps. We do not print a premium.

  1. The limit sentence. Send the page that says combined single limit or split limits, including the dollar figure the other party wrote.
  2. The vehicle. Year, make, model, gross vehicle weight rating, and whether it is owned, hired, or a personal vehicle used for the business.
  3. The use. Job sites, deliveries, or interstate for-hire loads. Interstate for-hire property carriage is the federal schedule above, not the state floor alone.
  4. The name. The insured name must match the business on the contract.
  5. Who must be listed. Additional insured or waiver wording, if the contract asks for it, copied from that contract.
  6. Callback. The form on this page. Call 209-670-1556.

Limits are not a price. $1,000,000 on a contract, and the figures in Vehicle Code section 16056 and 49 CFR 387.9, are liability limits.

What are split limits?

Split limits are three numbers: bodily injury per person, bodily injury per accident, and property damage. Each number caps its own part of the accident. Money left in the property-damage number cannot be moved over to pay a larger bodily-injury claim, and the reverse is also true.
