Car insurance "is not just a unique product.

  It is the most basic, it could be one or more of the following grouped:

  Liability insurance: what you pay for damage to cars and other people's health if you hit them

  Collision: what you pay for your car's repairs if it crashes and hits another person's car or post


  Complete: what you pay for repair or replacement if your car is stolen or damaged by fire, hail, etc.

  Only the first one is required.  Each type of coverage will also have its own deductible, and you can choose a higher deductible (which is basically less secure, a lower monthly premium) but forces you to pay more out of pocket when making a claim)
