Auto or car insurance coverage has two parts. The first is the liability section of the policy. It covers your financial responsibility for injuring others. Some liability coverage is required by most states.
The second part of auto insurance covers the car itself: comprehensive coverage reimburses losses from fire, theft or other perils; collision coverage pays to repair losses caused by an accident. Often this coverage is mandated by leasing companies or banks.
Utilizing high deductibles on the physical damage coverages can help reduce premiums.
