One way to reduce your auto insurance premium is to hike the deductible on your collision coverage and skimp on your liability coverage. Sometimes this can make sense, but often it's not worth the extra risk.
Bodily Injury Liability:
This coverage, which is required in most states, compensates the driver of the other car and its passengers in the event you get into an accident. It also covers the passengers in your car. The main consideration here is protecting your assets against lawsuits that arise from auto accidents. "But I'm a careful driver," you say. It doesn't matter. You can get sued even if the accident is not your fault.
Bodily injury liability is sold in standard increments that designate both how much coverage you have per person in an accident, with an additional limit per accident. For example, if you buy bodily injury worth $100,000/$300,000, each of the people you injured could be compensated $100,000, but only up to $300,000 per accident.
How much coverage you need is a function of what assets you have to protect. If you make $30,000 a year and rent your apartment, $50,000/$100,000 should suffice. But if you make more than $75,000 a year, own a house worth $150,000 and have $40,000 in mutual funds, you should consider at least $100,000/$300,000 of coverage.
In most cases the cost of increasing your Liability limits is very minimal.
One more option: If you have substantial assets, buy $300,000 in bodily injury on your auto policy and $300,000 on the liability portion of your homeowners policy. Then spend another $150 to $300 for a $1 million umbrella policy, which covers you against all manner of liability claims. Should you want still more coverage, the cost for an additional $1 million in coverage is minimal: It's typically $75 to increase your coverage to $2 million, and then $50 for each million after that, according to the Insurance Information Institute.
Property Damage Liability:
This coverage will pay for the repair and replacement of the other guy's car or property in the event of an accident. If you total some body's Lexus, do you have enough coverage to cover the damage?
You're better off with a minimum of $50,000 for each vehicle you own. And to be truly safe, you should have a total of $100,000 coverage.
Uninsured or Under insured Motorist:
This coverage pays for medical and funeral costs for you and your family in the event you get in an accident with either a hit-and-run driver or a driver who doesn't have enough auto insurance. These policies usually cover bike and pedestrian accidents, too. Given the prevalence of uninsured drivers nationally, this coverage is essential. On average, it costs less than $40 a year for $100,000 worth and will make up for anything your medical insurance doesn't cover. In Alaska 20-30% of accidents fall in the uninsured motorist category, not something to go without!
Collision and Comprehensive:
Collision reimburses you for the full cost of repairs or replacement of your car after an accident. Comprehensive covers you in the event your car falls victim to a natural disaster, vandalism or theft. With either coverage, the lower the deductible you choose, the more the policy will cost you. We recommend that you always choose the highest deductible you can afford ($1,000 is fine). After all, the purpose of insurance is to protect you against big losses, not to make you whole to the last dollar. If you have an older car, you might drop this coverage altogether.
Collision and comprehensive — which can account for 30% to 40% of your total premium — are cash-value coverages. That means if your car is damaged, the most you'll recoup is the Kelley Blue Book value, which declines precipitously as your car ages. Here's a good rule of thumb: If the cost of your collision and comprehensive is more than 10% of your car's Blue Book value, it probably makes sense to drop these coverages and save a tidy sum. With most cars, you should approach this limit as the car turns five years old. Understand, however, that if you eliminate the coverages, you'll have to foot the repair bill if you get in an accident that's your fault, or if the car is totalled or stolen.
Extras:
Consider rental-car reimbursement, which pays a paltry $15 or so a day while your car is in the repair shop after a collision. Not only is the reimbursement small, the odds you'll need it are remote. The chances are at least even that the other guy will be at fault, and his insurance will pay the full cost of this.

Text messaging, talking on a cell phone, styling hair, watching a movie, writing a grocery list, nursing a baby or putting in contact lenses: Secondary activities have become an everyday occurrence behind the wheel of American motorists. A growing shift in focus from the roadway to a multitude of other tasks impairs the ability of modern drivers, and the U.S. traffic statistics mark this drastic change.

If you plan to park those summer toys when the snow flies, make sure to call! Many items, such as motor homes and motorcycles have reduced coverage available for the winter lay-up. They will be covered for perils such as fire, theft, vandalism, falling objects, at just a fraction of the normal cost.
The largest myth:
If you have ever been in a car accident, the feeling of your heart racing and your adrenaline pumping, it is difficult to think clearly about the event and the things you need to do immediately following an accident. It is very important to document thoroughly to ensure that the claims process is handled as quickly and smoothly as possible. Even if there is police involved, the accident report filled by the policy officer may take days and may not have all the necessary information. We have a check sheet available to pick, or mail that will conveniently fit in your glove box.
