Car insurance can be costly but there are ways to reduce a premium without leaving the consumer at risk.

To start, take a defensive driving course. The six-hour course can save a person 10 percent for three years. And forget having to hole up in a classroom, as many companies now offer the courses online.

“I believe they give you 30 days to get it done. You’re doing the wash, you can then go and do an hour of the class and come back to it later,” said Nationwide agent Stephen Massa.

Speaking of classes, encourage teens to hit the books. Massa says many companies offer what's called a good student discount.

“If their grades are at least a B-average or higher, you'll get a discount, so that's an incentive to make your kid study,” said Massa.

Other strategies involve playing with the numbers a bit. Tobie Stanger of Consumer Reports said one way to lower your bill is to raise your deductible.

“If you were to go from a $200 deductible to a $500 deductible, you might be able to save as much as 30 percent,” said Stanger.

Second, as your car gets older, certain aspects of your policy might cost more than the car is worth.

“We recommend that you consider dropping collision and comprehensive when the annual premium is about 10 percent or more of your car's book value,” said Stanger.

However, one area expert said never skimp on the uninsured/underinsured motorist policy.

“Should you get into a crash and the other person doesn't have insurance, this portion of your insurance policy is going to cover that,” said Robert Sinclair Jr., the manager of relations at AAA New York.

It also covers members of your family should they be involved in a vehicle accident, even if they're not in the car. While most people have the minimum $25,000, Sinclair said that's probably not enough.

“You can spend a day in a hospital and rack up $25,000 dollars worth of coverage. You probably should have a half-million to $1 million worth of coverage,” said Sinclair.

But while there are plenty of discounts out there, in the end, the number one way to save money on car insurance is simply to drive safely.

“No accidents, no tickets. If your record's clean, you're gonna get a better shot of getting a really low rate,” said Massa.
