As personal injury attorneys who focus on auto accidents, we're often asked: "How much insurance is enough?" The answer is always: "It depends on what you have to lose."

After decades of representing accident victims in San Francisco and the Bay Area, we've seen countless cases where inadequate insurance left families devastated—not just from their injuries, but from financial ruin. The right insurance coverage isn't just about following the law; it's about protecting everything you've worked for.

The Critical Question: What Do You Have to Lose?

Your insurance needs directly correlate with your assets and income. Consider:

Homeowners

If you own your home, you have significant assets at risk. Insufficient coverage could result in losing your home to pay for accident damages.

Substantial Assets

Retirement accounts, savings, investments, and other wealth can be seized to satisfy judgments if you're underinsured.

High Earners

Future wages can be garnished for years to pay accident claims. Your earning potential is an asset that needs protection.

Family Protection

You're not just protecting yourself—you're protecting your spouse, children, and passengers who rely on you.

Bottom Line: If you have assets worth protecting or significant earning potential, minimum coverage is NOT enough.

Understanding California Auto Insurance Coverage Types

First, it's important to distinguish between the types of coverage available in California in order to know what suits your specific needs.

Liability Only

Covers the losses, damage, or injury you cause to others. This is the minimum required by California law.

Warning: Does NOT protect you or your vehicle. Only covers the other party's damages.

"Full" Coverage

Comprehensive protection including collision, comprehensive, medical payments, and uninsured/underinsured motorist coverage.

Recommended: Protects you, your vehicle, and your passengers in virtually all scenarios.

Breaking Down "Full" Coverage Components

Collision Coverage

Takes care of your vehicle in case of an accident where you are at fault or in single-vehicle accidents.

How It Works:

  • Your insurance company helps you get your car fixed
  • You only pay your deductible upfront
  • If your insurance company recovers costs from the responsible party, you'll be reimbursed your deductible

Our Recommendation: Carry a $500 deductible or less. This makes getting your car fixed after an accident much easier and quicker.

Comprehensive Coverage

Covers damage to your car in "no fault" situations where no other driver is responsible.

What It Covers:

Falling objects (tree branches, etc.)
Weather damage (hail, flooding)
Fire or explosion
Theft or vandalism
Animal strikes (deer, etc.)
Glass breakage

Our Recommendation: Carry a $100 deductible or no deductible. San Francisco's urban environment poses numerous comprehensive risks.

Medical Payments Coverage (Med Pay)

Pays for medical treatment after an accident, regardless of who's at fault.

Coverage Details:

  • Generally ranges from $500 to $10,000
  • Covers emergency room care and ambulance services
  • Covers medical treatment related to auto accidents
  • Available to the driver and passengers in your vehicle
  • Supplements your or your passengers' health insurance

Do You Need It? Medical payments coverage is not essential if you have good health care coverage. However, if you don't have good health insurance, you should consider carrying at least $5,000-$10,000 in med pay coverage.

⭐ Most Critical Coverage ⭐

Uninsured & Underinsured Motorist Coverage

This is EXTREMELY important to carry—and here's why

The Harsh Reality in California

• 16.6% of California drivers are UNINSURED (approximately 1 in 6 drivers)

• Many drivers carry only minimum liability ($15,000/$30,000 in California)

• Medical bills from serious injuries easily exceed $100,000+

• Without UM/UIM coverage, YOU pay the difference

What This Coverage Does:

Uninsured Motorist (UM) Coverage

Protects you and your passengers when the at-fault driver has NO insurance at all. This includes hit-and-run accidents where the responsible driver is never found.

Example: An uninsured driver runs a red light and T-bones your car, causing $200,000 in medical bills and lost wages. Without UM coverage, you're on your own.

Underinsured Motorist (UIM) Coverage

Covers you when the at-fault driver doesn't have ENOUGH insurance to cover all the losses sustained. This is actually more common than uninsured drivers.

Example: A driver with minimum $15,000 liability causes an accident resulting in $150,000 in damages. UIM coverage pays the $135,000 difference.

Extended Coverage Benefits:

Some policies extend UM/UIM coverage beyond just accidents in your own vehicle:

  • Passenger in another vehicle: You're covered even when riding in someone else's car that doesn't have UM/UIM
  • Household members: Your spouse and children may be covered when they're passengers or driving other vehicles
  • Pedestrian or cyclist: Some policies cover you if you're hit while walking or riding a bike

Real-World Example from Our Practice

A client was rear-ended on Highway 101, suffering severe back injuries requiring surgery. The at-fault driver had only $15,000 in liability coverage—California's minimum. Our client's medical bills exceeded $180,000, plus lost wages of $40,000.

Without UIM Coverage:

Client receives only $15,000. Out of pocket: $205,000+

With $100K/$300K UIM:

Client receives full $100,000 for single victim, plus the $15,000 = $115,000

UM/UIM coverage literally saved our client from financial devastation. This is why we call it the most important coverage you can buy.

Beahm Law's Insurance Coverage Recommendations

Based on decades of representing accident victims in California

1

Minimum Coverage for All Drivers

When clients ask us "how much insurance is enough," we recommend that individuals generally should have at least:

$100,000/$300,000

Liability Coverage

$100,000/$300,000

Uninsured Motorist

$100,000/$300,000

Underinsured Motorist

What This Means:

  • $100,000 maximum per person injured
  • $300,000 maximum total per accident (multiple victims)
  • This amount ensures passengers in your car are covered if you're at fault, and provides protection if the at-fault driver lacks adequate insurance
2

For Homeowners & High-Asset Individuals

If you own a home or have significant personal assets or wealth, you want to have MORE coverage to protect what you've built:

Higher Liability Limits:

Consider increasing to $250,000/$500,000 or even $500,000/$1,000,000 liability coverage

Umbrella/Excess Liability Policy:

Check your homeowner's policy to confirm you have "umbrella" or "excess" liability coverage. This provides an additional $1-5 million in liability protection that covers both your auto and home.

Cost-Effective: Umbrella policies are surprisingly affordable (often $200-400/year for $1M coverage) and provide exceptional protection for high-net-worth individuals.

Match Your UM/UIM to Liability:

Whatever liability limits you choose, match them with equal UM/UIM coverage. If you have $250K/$500K liability, get $250K/$500K UM/UIM.

Deductible Recommendations

Comprehensive:

$100 or $0 Deductible

Lower deductibles for comprehensive make sense because these claims (theft, vandalism, weather) don't affect your rates as much as collision claims.

Collision:

$500 or Less

This makes getting your car fixed after an accident much easier and quicker without a huge out-of-pocket expense.

Quick Reference: Recommended Coverage Levels

Coverage Type Minimum Recommended Homeowners/High-Asset
Liability $100K/$300K $250K/$500K or higher
Uninsured Motorist $100K/$300K $250K/$500K or higher
Underinsured Motorist $100K/$300K $250K/$500K or higher
Medical Payments $5K-$10K (if no health insurance) $5K-$10K (if no health insurance)
Comprehensive Deductible $100 or $0 $100 or $0
Collision Deductible $500 or less $500 or less

Note: Homeowners should also verify they have an umbrella/excess liability policy for an additional $1-5M in protection.

Common Insurance Mistakes We See

Carrying Only State Minimum Coverage

California's minimum ($15K/$30K) is woefully inadequate. A single serious injury easily exceeds these limits.

Skipping UM/UIM Coverage

With 1 in 6 drivers uninsured, this is gambling with your financial future.

Not Matching UM/UIM to Liability Limits

You're protecting others better than you're protecting yourself.

Choosing High Deductibles to Save Money

A $1,000-$2,000 deductible saves a few dollars monthly but creates financial hardship after an accident.

Not Reviewing Coverage Regularly

As your assets grow (home equity, savings, retirement), your insurance should grow too.

Review Your Coverage Today

Don't wait until after an accident to realize you're underinsured. Take these steps now to ensure you have adequate protection:

Pull Out Your Policy and Review It

Look at your current liability, UM/UIM, and deductible amounts. Compare them to our recommendations above.

Call Your Insurance Agent

Get quotes for increasing your coverage. The cost difference is often surprisingly small compared to the protection gained.

Consider Your Assets and Lifestyle

As your life changes—buying a home, having children, building wealth—your insurance should change too.

Add Umbrella Coverage if You Own a Home

This relatively inexpensive addition provides millions in extra liability protection for both your auto and home.

The best time to increase your coverage is before you need it. A few extra dollars per month in premiums can save you from financial devastation.
