California Auto Insurance Requirements

California has specific auto insurance requirements that producers must understand.

Mandatory Coverage

California requires all registered vehicles to have liability insurance with minimum limits:

Minimum Liability Limits (15/30/5)

CoverageMinimum Limit
Bodily Injury per Person$15,000
Bodily Injury per Accident$30,000
Property Damage$5,000

Proof of Insurance

California drivers must carry proof of insurance:

  • Physical insurance card, OR
  • Electronic proof on smartphone (California accepts electronic proof)
  • SR-22 required for certain violations
  • Penalties for driving without insurance include fines and vehicle impoundment

California's At-Fault System

California uses a "pure comparative negligence" system:

How It Works

  • The driver at fault is responsible for damages
  • Fault can be shared between drivers
  • Recovery reduced by percentage of fault
  • Even a driver 99% at fault can recover 1% of damages

Example

If Driver A is 70% at fault and Driver B is 30% at fault:

  • Driver A can recover 30% of their damages from Driver B
  • Driver B can recover 70% of their damages from Driver A
