California Car Insurance Policy Terminology 101

• Liability Limits - This is the part of the policy that shows how much protection your have in the case of either a bodily injury or property damage accident.
  In California, the state requires a minimum of $15,000 for injury or death to one person, $30,000 for injury or death to more than one person, and $5,000 for damage to property.
  Your car insurance policy may state 15/30/5 limits or if you have greater limits, they may read 100/300/100 or 250/500/100 or many other variations.
  If you do not carry liability insurance, your drivers license may be suspended, your vehicle registration may be suspended, you may be ticketed, your vehicle may be impounded and in the case of an accident, you will be personally liable to compensate for any damages you caused.
  
• Uninsured/Underinsured Motorists Coverage (UM/UIM) - This car insurance coverage is commonly misunderstood by consumers and is an important part of your California car insurance policy.
  If another driver causes an accident that you are injured in, and they carry low liability limits or worse, no insurance at all, your UM/UIM coverage will kick in to pay for your medical bills.
  This is coverage for YOU, not the other driver.
  
• Medical Payment or Personal Injury Protection Coverage - This coverage is considered "no-fault" coverage and pays for medical expenses of you or your passengers in your car.
  What most consumers don't know, is that this coverage may apply if you are injured as a pedestrian or while entering or exiting a vehicle.
  
• Comprehensive or Other-than-Collision Coverage - This coverage protects your vehicle for damage from anything other than collision with another vehicle or object.
  The exception is a collision with a bird or animal, which falls under comprehensive coverage.
  Examples of covered claims are hail, fire or flood.
  
• Collision Coverage - This coverage pays for damage to your vehicle when it hits, or is hit by, another vehicle or object.
  If you are involved in a car accident, your collision coverage is the protection that will pay to repair your vehicle.
  
• Roadside Assistance or Towing Coverage - Insurance companies use different descriptions for this coverage, and benefits may differ between carriers.
  This coverage will provide reimbursement if your vehicle needs towed or other roadside assistance such as a flat tire.
  
• Rental Reimbursement - In the event that your vehicle is damaged and is required to be in the repair shop, this coverage will pay for a rental vehicle for you to drive.
  Limits are usually stated on a daily basis and a total limit, such as 30/600, which would provide coverage at $30 per day up to a limit of $600.
  
• Deductible - This is the amount that you choose to pay before the insurance company will pay any amount for comprehensive or collision claims.
  Deductibles allow you to lower your California car insurance premiums by choosing a higher deductible.
