There is no public database in California where you can look up another driver’s auto insurance policy limits. To find out someone’s insurance policy limits in California, you generally have two options: send a written request to their insurance company before filing a lawsuit (which only works if the policyholder consents to the disclosure), or file suit and use the discovery process, which forces the other side to turn over the policy details under oath. Which path you use depends on how cooperative the insurer and policyholder are, and how much is at stake.
Why You Can’t Just Call and Ask
California treats insurance policies as private contracts between the insurer and the policyholder. Under California Insurance Code Section 791.13, an insurer generally cannot disclose a policyholder’s personal or privileged information to a third party without the policyholder’s written consent.1California Legislative Information. California Insurance Code 791.13 – Disclosure of Personal or Privileged Information That rule is the reason an adjuster will not read you the dec page over the phone, even if you were hit by their insured yesterday.
It also explains why context matters. California’s minimum liability limits went up on January 1, 2025, to $30,000 for bodily injury per person, $60,000 per accident, and $15,000 for property damage.2California Department of Insurance. Bulletin 2023-1 Re SB 1107 Many drivers carry exactly that floor. If your medical bills are $80,000 and the other driver has only $30,000 in bodily injury coverage, the gap is yours to absorb unless you have your own underinsured motorist coverage to fall back on. That’s why confirming the actual limits matters before you invest months in a claim.
Step One: Identify the Insurer
Before you can ask about limits, you need to know which company to ask. California drivers must carry evidence of financial responsibility in the vehicle and are expected to exchange insurance information at the scene.3California Legislative Information. California Vehicle Code 16020 If you have the carrier name and policy number from the scene, you can skip ahead. If you don’t, two public records close the gap.
The Police or CHP Collision Report
California Highway Patrol and local police reports list each driver’s insurance carrier and policy number. You can request a CHP report by mail; the fee starts at $10 for reports up to 25 pages and goes up in $10 increments for each additional 25-page block.4California Highway Patrol. Collision Report – CHP 190 Local departments set their own fees. These reports identify the insurer but do not state dollar limits.
The SR-1 Filed With the DMV
Every driver in a California collision must file a Report of Traffic Accident (Form SR-1) with the DMV within 10 days if anyone was injured or property damage exceeded $1,000.5California DMV. Report of Traffic Accident Occurring in California (SR-1) You can submit a Public Records Act request to the DMV for a copy. The DMV must respond within 10 days, though producing the document itself may take longer.6California DMV. Public Records Act, Freedom of Information Act, or Information Practices Act Like the police report, the SR-1 names the carrier and policy number without listing coverage amounts.
Step Two: Send a Written Request to the Insurer
Once you know the carrier, send a written request for the policy limits. The insurer should then contact its policyholder in writing to ask whether disclosure is authorized. If the insured consents, the insurer releases the limits. If the insured refuses or ignores the request, the insurer typically will not disclose.
Make the request worth responding to. Include the insured’s full name, the claim number if one exists, the date and location of the accident, and a summary of your injuries or property damage. Attach medical records, bills, or repair estimates. A request that demonstrates real claim value gives the policyholder a reason to consent, because disclosing limits is often the first step toward a settlement that resolves the matter without a lawsuit.
An insurer that refuses as a matter of policy, or refuses even to ask its own insured for consent, is not acting without risk. California courts have recognized that a wholesale refusal to seek the policyholder’s consent forecloses pre-litigation settlement and can support a later bad faith finding. The claimant still has no automatic right to the limits, but the insurer’s silence can come back to haunt it.
Step Three: Use Discovery After Filing Suit
If the pre-litigation request fails, filing a lawsuit opens the most reliable path. California Code of Civil Procedure Section 2017.210 lets any party discover the existence and contents of insurance agreements that might cover a judgment, including the carrier’s identity, the type of coverage, and the dollar limits.7California Legislative Information. California Code of Civil Procedure 2017.210 The statute also makes clear that disclosing the information in discovery does not make it admissible at trial. The jury won’t hear it; the information is for settlement and case planning.
Form Interrogatory 4.1
The fastest tool is California’s Form Interrogatories—General (DISC-001). Checking box 4.1 requires the defendant to state, under oath, whether an insurance policy was in effect at the time of the incident, the kind of coverage, the insurer’s name and address, each named insured, the policy number, the limits for every type of coverage, whether any coverage dispute exists, and who holds the policy.8Judicial Council of California. Form Interrogatories – General DISC-001 You don’t draft anything; you check the box and serve the form.
Request for Production
You can also serve a Request for Production asking for the policy’s declarations page. The dec page is the summary sheet listing every coverage type with its dollar limit, including any umbrella or excess policies sitting above the primary policy. Having the actual document in hand removes any ambiguity about what the interrogatory answers meant.
If the Defendant Stonewalls
A defendant who refuses to respond or gives evasive answers faces monetary sanctions under Code of Civil Procedure Section 2023.030, which can include attorney’s fees caused by the noncompliance.9Justia Law. California Code of Civil Procedure 2023.010-2023.040 – Sanctions The court can also compel a response, and continued defiance can escalate to evidence sanctions or striking the answer. In practice, most defendants comply, because no legitimate privilege shields the information once suit is filed.
If the Case Is in Federal Court
Federal court is more generous. If the parties are citizens of different states and the amount in controversy exceeds $75,000, the case may land there.10Constitution Annotated. Overview of Diversity Jurisdiction Federal Rule of Civil Procedure 26(a)(1)(A)(iv) requires each party to produce any insurance agreement that could satisfy a judgment, without being asked. The disclosure happens automatically within 14 days of the parties’ planning conference, or 30 days for a party joined later.11Legal Information Institute (LII). Rule 26 – Duty to Disclose; General Provisions Governing Discovery You get the policy as a matter of course.
Time-Limited Policy Limits Demands
A time-limited demand is a settlement offer to the insurer offering to resolve the claim for the policy limits if the insurer accepts within a set deadline. Under California Code of Civil Procedure Section 999, a pre-lawsuit time-limited demand must give the insurer at least 30 days to respond when sent by email, fax, or certified mail, or 33 days by regular mail. A shorter deadline loses the statute’s protection.
The leverage comes from what happens if the insurer unreasonably refuses. If the case later goes to judgment and the verdict exceeds the policy limits, the insurer’s refusal to accept a reasonable within-limits demand can expose it to the full excess judgment. This is the mechanism behind bad faith liability, and it is often what finally gets an insurer to disclose and offer the limits. The statute requires an insurer that declines to notify the claimant in writing before the deadline expires, explaining why; that written refusal becomes evidence in any later bad faith suit. One caveat: Section 999’s protections do not apply to claimants without an attorney, so this tool realistically belongs to represented claimants.
Commercial Trucks Are Different
If the other vehicle is a commercial truck or bus, the information is public. The Federal Motor Carrier Safety Administration requires interstate motor carriers to maintain minimum liability coverage based on cargo: $750,000 for non-hazardous property in vehicles over 10,001 pounds, $1,000,000 to $5,000,000 for hazardous materials, $1,500,000 for passenger vehicles with 15 or fewer seats, and $5,000,000 for larger passenger vehicles.12eCFR. 49 CFR Part 387 – Minimum Levels of Financial Responsibility for Motor Carriers
You can look up a carrier’s active insurance filing on the FMCSA’s Safety and Fitness Electronic Records (SAFER) system for free, searching by company name or the USDOT number printed on the side of the truck.13Federal Motor Carrier Safety Administration. SAFER Web The MCS-90 endorsement attached to every regulated carrier’s policy serves as proof of financial responsibility and applies to all vehicles the carrier operates.14Federal Motor Carrier Safety Administration. Form MCS-90 – Endorsement for Motor Carrier Policies of Insurance for Public Liability No consent, no discovery, no lawsuit required.
When the Limits Won’t Cover Your Losses
Finding out the limits sometimes just confirms bad news: the at-fault driver has the state minimum and your losses are much larger. Your own policy is the backup. California requires every auto liability policy to include uninsured motorist (UM) coverage at least equal to the state minimum of $30,000 per person and $60,000 per accident, and insurers must also offer underinsured motorist (UIM) coverage at matching limits.15California Legislative Information. California Insurance Code 11580.2 You can waive or reduce these in writing, but without a signed waiver, your policy includes them by default.
A UIM claim is a two-step process. You exhaust the at-fault driver’s liability limits first, then claim the gap against your own insurer up to your UIM limits. If the other driver has $30,000 and your medical bills come to $90,000, your UIM coverage picks up the difference to the extent of its own limits. The whole reason to find out the other driver’s limits early is to know whether this second step will be necessary, and to plan the claim around both policies from the start rather than discovering the shortfall after months of back-and-forth.
