Will Making an Uninsured Motorist Claim Raise My Insurance Rates in California?

If you’ve been in a car accident with an uninsured driver, you’re likely wondering: will my insurance go up if I use an underinsured motorist claim? Or more broadly, does uninsured motorists claim an increased premium? These are some of the most common questions we hear at Sally Morin Personal Injury Lawyers. The fear of skyrocketing rates can make filing a claim feel risky—but in California, the answer is often reassuring. In this comprehensive guide, we’ll break down what uninsured motorist coverage is, how it works, whether it impacts your premiums, and what to do next to protect your rights and finances.

With nearly 4.1 million uninsured drivers on California roads—about 10% of all motorists—collisions with them are all too common. These drivers violate state law by skipping liability coverage, yet they’re involved in 15% of accidents despite making up just 10% of the population. If you’re hit by one, your uninsured motorist coverage (UM) or underinsured motorist coverage (UIM) steps in to cover your damages when the at-fault party can’t. But should you hesitate to file? Let’s dive in.

The Nationwide Reality: Why Uninsured Motorist Claims Often Raise Premiums

You’ve probably heard the horror stories: A friend in a no-fault crash files an uninsured motorist claim, and their rates jump 15% or more. These tales are frustratingly common—and unfortunately, they’re grounded in reality outside California.

In most states, insurers can hike premiums after any claim, even if you’re not at fault. A nationwide study by The Zebra analyzed rate changes and found that uninsured motorist claims lead to an average 9.32% increase. Here’s how major providers stack up:

Insurers justify this by viewing any accident as a “risk signal.” They use algorithms factoring in your driving record, age, vehicle type (yes, even color), parking location, and mileage to predict future claims. An uninsured motorist accident—even one you didn’t cause—flags you as higher risk, prompting them to “hedge bets” and recoup costs upfront.

But here’s the good news: If you live in California, they’re not allowed to do this.

California Law Protects You: Proposition 103 and Uninsured Motorist Claims

California stands out as one of just two states (alongside New York) with strong protections for innocent drivers. Proposition 103, passed in 1988 and upheld by the state legislature, explicitly forbids insurers from raising rates solely because you file an uninsured motorist claim after a no-fault accident.

This means your premiums cannot legally increase for using your UM or UIM coverage to cover medical bills, lost wages, or property damage from an uninsured driver’s negligence. As a California personal injury attorney with over a decade of experience, I’ve seen clients breathe a sigh of relief upon learning this—many avoid claims out of unfounded fear, leaving themselves financially exposed.

Exceptions exist, but they’re narrow:

• Multiple claims: Two or more UM/UIM claims in a short period (e.g., 2-3 years) could signal higher risk, allowing a review.
• Policy violations: See our section below on exceptions.

This protection removes a major barrier to justice. Still, filing isn’t always smooth—insurers may deny or lowball claims, which is why expert guidance is key.

Step-by-Step Guide to Filing an Uninsured Motorist Claim in California

Wondering what is uninsured motorist coverage in action? It’s your safety net for bodily injury and property damage when the at-fault driver has no (or insufficient) insurance. Unlike liability coverage, which protects others, UM/UIM protects you. California requires insurers to offer it, but you can opt out—don’t.

Here’s a clear, step-by-step guide to filing successfully:

1. Ensure Coverage: Confirm your policy includes UM/UIM (minimum: $15,000 per person/$30,000 per accident for bodily injury). Match it to your liability limits for full protection.
2. Gather Evidence Immediately: Document the scene with photos, witness statements, and a police report. Note the other driver’s lack of insurance (e.g., no proof provided).
3. Notify Your Insurer Promptly: Report the accident within your policy’s timeframe (often 30 days). Provide all evidence to establish fault on the uninsured driver.
4. Submit Your Claim: Detail damages (medical bills, repairs, lost income). Use California’s three-year statute of limitations for personal injury claims as a deadline.
5. Negotiate or Litigate: Expect an initial low offer—insurers aim to minimize payouts. If denied, appeal or involve an attorney to enforce your rights under Prop 103.
6. Track Everything: Keep records of communications to avoid “nitpicking” denials over paperwork.

Pro Tip: Even pedestrians and cyclists qualify for UM coverage. Learn more about underinsured motorist insurance for non-drivers here.

Following these steps maximizes your payout without risking unwarranted rate hikes.

Filing a Claim Doesn’t Guarantee Easy Payment—And Lowballs Are Common

Even with California’s protections, insurers aren’t charities. They can deny claims by disputing fault, questioning injury severity, or claiming improper filing. If approved, the first offer is often a fraction of your needs—designed to cut costs while leaving you scrambling for bills.

That’s where experience matters. A skilled attorney can:

• Prove fault with evidence.
• Negotiate fair settlements (often 2-3x higher).
• Speed up processing to avoid delays.

Don’t go it alone—consult a lawyer early to boost your odds.

Why Do Rates Sometimes Rise Anyway? Understanding the Myths and Realities

If Prop 103 bans increase, why the stories? Often, it’s not the UM claim itself but a broader risk reassessment. Insurers reevaluate policies annually, weighing factors like accident frequency. One claim rarely triggers a hike, but 3-4 in 2-3 years? That could label you “high-risk.”

Other culprits:

• At-fault perceptions: If fault is unclear, it might ding your record.
• Med-pay overlap: Using medical payments coverage alongside UM can compound scrutiny.

Bottom line: A single uninsured motorist claim won’t automatically raise rates, but patterns matter. Shop around if hikes occur—switching providers resets your risk profile.

Exceptions to Proposition 103: When Rates Can Still Increase

Prop 103 isn’t ironclad. Amendments outline three scenarios where insurers can raise rates post-claim, potentially voiding protections:

1. Non-Payment of Premiums: Miss deadlines? Your policy lapses, and reinstatement could mean higher rates. Always pay on time—it’s a binding contract.
2. Fraud or Misrepresentation: Exaggerate damages or lie on forms? Expect cancellation, fines, and hikes. Honesty protects you.
3. Substantial Risk Increase: Multiple accidents (even no-fault), sudden high mileage, speeding tickets, or riskier vehicles (e.g., sports cars) justify adjustments. Environmental factors (like wildfire-prone areas) apply to home policies too.

New Section: Risks of Skipping a Claim Altogether

Tempted to pay out-of-pocket to avoid “flags”? Think again. Unreported accidents can backfire:

• Gaps in Coverage: Future claims might be denied if the insurer views you as hiding incidents.
• Financial Ruin: Average crash medical costs hit $15,400+ in 2013 (now higher with inflation)—far exceeding repair bills.
• Legal Exposure: If injuries surface later, you’re out of time under statutes of limitations.

Not filing often costs more long-term. Always report to preserve your record.

Why You Absolutely Need Uninsured Motorist Coverage in California

If claims sound daunting, here’s why UM/UIM is non-negotiable: California’s minimum liability is just $15,000—woefully inadequate for serious injuries. Without UM, you’re stuck chasing broken drivers for compensation.

Benefits include:

• Bodily Injury Protection: Covers medical, pain, and lost wages.
• Property Damage: Repairs your vehicle.
• Hit-and-Run Coverage: Applies even without a driver ID.
• Versatility: Protects as a passenger, pedestrian, or cyclist.
