“Key Takeaways”

• 10-Day Reporting Deadline: Under Insurance Code § 11580.2, you must report a hit-and-run to law enforcement within 10 days to qualify for UM coverage. Failure to do so may result in denial of your claim.
• Physical Contact Requirement: For hit-and-run UM claims, there must be physical contact between the vehicles. If there is no contact, you cannot recover unless you can prove the fleeing driver forced you off the road.
• Stacking Coverage: If you have multiple vehicles or policies, you may be able to stack UM coverage—adding limits together for greater recovery.
• UIM Coverage: When the at-fault driver has insurance but insufficient limits, your underinsured motorist (UIM) coverage pays the difference.
• Two-Year Statute of Limitations: Under CCP § 335.1, you have two years to file a lawsuit. For UM claims, the clock may start when you discover the driver was uninsured.

The Uninsured Motorist Crisis: When the At-Fault Driver Leaves You Holding the Bag

You’re driving home on a familiar San Diego road—perhaps Interstate 5 through Downtown, Highway 163 through Balboa Park, or a quiet street in La Jolla. Another driver runs a red light, slams into your car, and causes serious injuries. You exchange information, confident that their insurance will cover your medical bills and lost wages. Then you discover the devastating truth: the at-fault driver had no insurance.

Every year, thousands of California drivers are injured in accidents caused by uninsured motorists. According to estimates, approximately 1 in 7 California drivers is uninsured. When you’re hit by one of them, your own uninsured motorist (UM) coverage becomes your lifeline.

At Leeran S. Barzilai, A Prof. Law Corp., we know how to navigate the complex world of UM claims, enforce your rights against your own insurance company, and maximize your recovery through stacking, UIM coverage, and aggressive negotiation with carriers like State Farm, GEICO, Farmers, Allstate, Progressive, Mercury, AAA, USAA, Liberty Mutual, Travelers, Hartford, Nationwide, and Kemper.

The Uninsured Motorist Landscape: What You’re Up Against

California’s Uninsured Driver Problem

Statistic	Implication
~15% of California drivers are uninsured	Your chances of being hit by an uninsured driver are significant
Minimum liability limits are $15,000 per person	Even insured drivers often carry inadequate coverage
UM coverage is mandatory unless rejected in writing	Most drivers have UM coverage, but may not understand it
Hit-and-run accidents are treated as UM claims	Fleeing drivers are presumed uninsured under the law

What UM Coverage Protects

Your uninsured motorist coverage protects you when:

• The at-fault driver has no insurance
• The at-fault driver is a hit-and-run driver who cannot be identified
• The at-fault driver’s insurance company denies coverage (e.g., for policy violations)
• The at-fault driver’s insurance limits are insufficient (this is UIM coverage)

The Legal Mechanics of an Uninsured Motorist Claim

Step 1: Verify the At-Fault Driver’s Insurance Status

Immediately after an accident, we investigate the at-fault driver’s insurance status:

Scenario	Action
Driver has no insurance	File UM claim with your own insurer
Driver is insured but limits are low	Pursue UIM claim after exhausting their policy
Driver flees the scene	Report to police within 10 days; file UM claim
Driver’s insurer denies coverage	Pursue UM claim; challenge denial if appropriate

Step 2: The 10-Day Hit-and-Run Reporting Deadline

Under California Insurance Code § 11580.2, if the at-fault driver flees and remains unidentified, you must report the accident to law enforcement within 10 days to qualify for UM coverage .

Requirement	Deadline	Consequence of Missing
Report hit-and-run to police	Within 10 days	Your UM claim may be denied
Notify your insurance carrier	As soon as possible	Potential coverage disputes
Preserve evidence	Immediately	Critical evidence (surveillance footage) is overwritten

Strategic Note: At Leeran S. Barzilai, A Prof. Law Corp., we ensure you meet this deadline. We file the police report, notify your insurance carrier, and document compliance to prevent coverage disputes with carriers like State Farm, GEICO, AAA, or USAA.

Step 3: The Physical Contact Requirement for Hit-and-Run UM Claims

Under Insurance Code § 11580.2(b), for a hit-and-run accident to be covered by UM insurance, there must be physical contact between the vehicles .

Situation	Covered?	Evidence Needed
Fleeing vehicle hits your car	Yes	Paint transfer, vehicle damage, witness statements
Fleeing vehicle forces you off the road without contact	Possibly, but difficult	Strong evidence (independent witnesses, skid marks, accident reconstruction)
Fleeing vehicle causes you to swerve and hit another object	No, unless you can prove the fleeing driver’s identity	Not covered under standard UM policies

We work with accident reconstruction experts, paint transfer analysis, and witness statements to prove physical contact occurred.

Step 4: Stacking Your UM Coverage

If you have multiple vehicles insured under the same policy, or multiple policies covering different vehicles in your household, you may be able to stack UM coverage—adding the limits of each vehicle together to increase your total available coverage .

Example:

• Vehicle 1: $50,000 UM coverage
• Vehicle 2: $50,000 UM coverage
• Stacked total: $100,000 available

Stacking applies to:

• Multiple vehicles on the same policy
• Multiple policies covering different vehicles in the same household
• UM and UIM coverage

Strategic Note: At Leeran S. Barzilai, A Prof. Law Corp., we analyze your entire insurance portfolio to identify stacking opportunities that maximize your recovery.

Step 5: Underinsured Motorist (UIM) Claims

When the at-fault driver has insurance, but their policy limits are insufficient to cover your damages, your underinsured motorist (UIM) coverage pays the difference .

Example:

• Your total damages: $100,000
• At-fault driver’s policy limits: $30,000
• Your UIM coverage: $50,000
• Total recovery: $30,000 + $50,000 = $80,000 (subject to policy limits)

UIM claims require careful coordination:

1. Exhaust the at-fault driver’s policy limits
2. Obtain documentation of the limits and exhaustion
3. File UIM claim with your own insurer
4. Negotiate or arbitrate the UIM claim

Proving Your Uninsured Motorist Claim: Evidence Collection

Critical Evidence in UM/UIM Cases

Evidence Type	Why It Matters
Police Report	Documents the accident; may note whether the other driver had insurance
Insurance Policy	Provides your policy limits and confirms UM/UIM coverage
Medical Records	Documents the nature and extent of your injuries
Lost Wage Documentation	Proves economic damages
Photographs	Shows vehicle damage and scene conditions
Witness Statements	Corroborates fault and physical contact
Surveillance Footage	May capture the fleeing vehicle or document the accident
Accident Reconstruction	Proves fault and physical contact in hit-and-run cases

What to Do Immediately After an Accident with an Uninsured Driver

1. Call 911 and request a police report. The report will document whether the other driver had insurance.
2. Seek medical attention immediately. Document your injuries.
3. Exchange information with the other driver, but do not rely on their insurance status.
4. Photograph the scene, vehicle damage, and any injuries.
5. If the driver flees, report to police immediately. Ask for the report number and document the 10-day reporting deadline.
6. Notify your insurance company—but do not give a recorded statement without speaking to an attorney first.
7. Contact an experienced UM attorney immediately to protect your rights.

Dealing with Insurance Companies: Your Carrier and Theirs

Your Own UM/UIM Claim

When you file a UM or UIM claim, you are dealing with your own insurance company. Major carriers you may be dealing with include:

Insurance Carrier	Typical Approach to UM/UIM Claims
State Farm	May attempt to dispute the extent of your injuries; thorough documentation required
GEICO	Often uses recorded statements to find inconsistencies; may delay payment
Farmers Insurance	May dispute fault or the severity of injuries; requires strict documentation
Allstate	Known for aggressive defense of UM claims; may undervalue your injuries
Progressive	Uses data analytics; may make algorithmic initial offers
Mercury Insurance	California-based; often requires strict compliance with policy provisions
AAA	Local club adjusters have discretion; may be slow to respond
USAA	Serves military members; generally reputable but still requires documentation
Liberty Mutual	Often handles UM claims through specialized adjusters
Travelers	Thorough investigation; may delay while seeking evidence
Hartford	AARP-affiliated; may have unique policy provisions
Nationwide	Standard claims practices; may dispute causation
Kemper	Smaller carrier; may have limited claims resources

When Your Own Insurer Disputes Your Claim

Your own insurance company may attempt to deny or undervalue your UM/UIM claim by arguing:

• The other driver was not actually uninsured
• Your injuries were pre-existing or not caused by the accident
• Your damages are less than you claim
• You failed to report the hit-and-run within 10 days
• There was no physical contact (in hit-and-run cases)

We aggressively counter these arguments with evidence, expert testimony, and, if necessary, arbitration or litigation.

---

The Statute of Limitations for UM/UIM Claims

Under Code of Civil Procedure § 335.1, you generally have two years from the date of the accident to file a lawsuit .

For UM/UIM claims against your own insurer:

• The two-year deadline applies
• The clock may start when you discover or reasonably should have discovered the driver was uninsured or underinsured
• This is complex; do not assume you have more time

At Leeran S. Barzilai, A Prof. Law Corp., we track these deadlines to protect your rights.
